Hormones Research Papers Samples For Students

It is not a secret to anyone that our body and the systems it consists of are controlled by a number of things. Naturally, everyone thinks of our brain as a control organ, when it comes to sending order within our body, however, not everyone knows that there are also hormones that shape our entire life. There are two regulatory systems by which the body adjusts to changes in the environment, circumstances and our daily routine. The first one is our central nervous system, with our brain as a major organ in that system, quickly transmitting a signal (in pulses) via a network of nerves ...

Summary of article one The first article titled “An Overview of the Pituitary Gland: The Endocrine System's Master Gland’’ begins by restating the role pituitary gland. According to this article pituitary gland produces hormones which have effects on the various parts of the endocrine system. These include adrenal glands, thyroid glands, ovaries and testes. The author goes on to state that pituitary, which measures about one third of an inch is located at the base of the brain next to another important part of the brain called the hypothalamus. Both hypothalamus and pituitary gland functions overlap according to Reham. ...

Introduction

In the year 2005, a total of 32.49 million cows were slaughtered and the products supplied for consumption to the United States residents. According to the perception of the scientists, more than half of these cows contained hormones that could enhance their fast growth (King 22). In addition, in the daily milk-producing cows, genetically modified hormones were injected to enhance an increase in the level of milk production (King 22). These measures meant that there could be an increase in the profit in this industry of beef and dairy products production. However, what does this mean to the children who ...

Hormone Variations During Pregnancy

Hormone Variations During Pregnancy

Introduction

Pregnancy is regarded is one of the most important phase of a women’s life cycle. In addition, pregnancy also encompasses hormonal and physiological changes that are unique in the women’s life cycle. In pregnancy, women experience sudden changes, which includes progesterone and estrogen increases. This also leads to dramatic changes on hormonal functions that affects mood and creates a “glow” among pregnant women. More importantly, hormonal changes during pregnancy poses a significant effect fetal development that also manifests in the changes in physical activities. Having to mention the progesterone and estrogen, medical studies suggests that women ...

Abstract

Bones are formed through a process known as osteogenesis from three different lineages. This process takes place through two different methods, which are intramembranous ossification and endochondral ossification. A large increment in bone mass takes place in childhood, as well as puberty, through the formation of endochondral bone. At this point, growth hormones are known to play a role. This paper will focus on the process of cartilage and bone formation and the stimulation of bone formation by the growth hormone. There are a number of factors that regulate the formation of bone, while growth hormone affects a number of factors related to ...

Introduction

Hyperthyroidism is a disorder that many are unaware of. A lot of people may have these symptoms but are not really aware of what is going on in their body. Many people suffer from this condition and just dismiss it as something that is minor. However, Hyperthyroidism is also something that has been overlooked by many people. One American study gave a report that stated that a prevalence that was somewhere around 500 per 100,000 persons, that had what was considered a lifetime risk of something that was like 1% in men and up to 2% in women. However, the research does ...

Pituitary

The different functions performed by the anterior and posterior pituitary in terms of sex
The anterior pituitary which is also known as the adenohypophysis, is basically an interior lobe (glandular) which alongside the posterior pituitary, makes up the pituitary gland. The posterior pituitary releases oxytocin which stimulates and smooth muscle contraction in the mammary glands and the uterus. The anterior pituitary on the other hand stimulates release of thyroid hormones, FSH and LH to stimulate sex cell production and release of sex hormones; it also stimulates sex cell production as well as secretes prolactin to stimulate milk production. ...

Teenagers experience hormonal imbalances which cause them to lose control and are mostly controlled by their sex drives. Sexual attractions are common during this developmental stage of life, and most ...

Introduction

Policy makers and the general public have been at pains to answer the questions they are confronted with about the intricacies of lesbians and gay men. Questions are abound ranging from whether they are mentally ill to whether the much publicized conversion therapies result to a change in orientation. Questions have also been asked about their stereotyped propensity to molest children. Such scathing thoughts and remarks are fed by stereotypic cultural undertones that many a times depict gay men and lesbians as criminals, immoral, sick and every description that falls short of what our society considers ‘normal’. The implicated individuals have ...

The study of endocrinology looks into ordinary and abnormal hormonal behavior. The endocrine system includes internal organs that secretes hormones. That is to say, endocrine glands secrete hormones into the bloodstream. These endocrine glands are essential organs of the human body that imperative to maintain various human functions, not to mention, life itself. Hormonal glands that make up the endocrine system influence many relevant factors such as pregnancy, capability to breast feed, and also the process of a child developing normally.
The endocrine system aids in the regulation of a human’s basic bodily functions. Given that, these functions ...

Homeostasis is dependent on the precision of the organs and organ system regulations in the body. The nervous system works together with the nervous system to regulate and offer coordination to the activities of almost all other parts of the body. Just like the nervous system, the endocrine system uses chemical known as hormones to communicate with other parts of the body. A hormone molecule is a specific messenger that is synthesized and released by specialized cells known as an endocrine gland. The endocrine glands are ductless with the hormones being released into the blood directly and taken to the ...

But the question arises as to when to begin, so that one can reap all the benefits of regular exercising. Although the best answer to this question is “here and now, “that is beginning exercises right away. However, childhood is the considered the best age to ...

Gender Identity

Specific behavioral patterns of great biological importance are mostly regulated by chemical substances produced by the brain. Most importantly, hormones have a role in differentiation of sexually dimorphic behavior. The term “hormone” is used to refer to a chemical substance that travels around the body influencing physiology and behavior (Bayliss & Starling, 1902). Intracranial functions could be influenced and altered by other substances found elsewhere. This paper is concerned with the neural-hormonal control of sexual behavior and the eventual determination of sexual identity.
As opposed to early studies of hormones on sexual behavior that were largely dominated by psychologists rather than ...

Rat Endocrinology

Hypothalamus
1. What is the molecular mechanism to release TRH?
TRH refers to the thyrotropin-releasing hormone. This hormone is produced by the hypothalamus. Before the full activity of TRH, some tightly controlled processes occur in the body including the appropriate folding of prohormone to move to the secretary pathway, the processing after translation, and movement of the peptides, which are processed, towards the secretary granules for secretion (Nillni n.p.).
TRH develops from bigger inactive precursor (known as proTRH) as a result of modifications after translation and moved through the controlled secretary pathway. Prohormone convertases (abbreviated as PCs) including PC1/3 ...

Introduction

According to William (2006), gender can be defined in terms of social classes (man or woman, boy or girl) or factors associated to living the social duties of man or woman. In addition, they argue that gender identity is the feeling of one belonging to either the category of women or men. On the contrary, he perceives intersexes as lacking gender identity. Additionally, according to He also argued that, there exists a strong relationship between hormones and behavior which consequentially influence the gender identity of an individual.

Thesis

Gender identity, a process of self-identification in relation to sex, can be based on either ...

Abstract

Continuous exposure to a wide spectrum of natural light has constructive impacts to not only one’s health but also their moods. The production of hormones such as serotonin and melatonin based on the intensity of light has a large impact on the distribution of an individual’s emotions. This study seeks to validate the role of sunlight in the distribution of a person’s mood and whether a lack thereof has a negative impact on their emotional balance. The paper utilizes similar researches conducted on this issue to establish an argument about the constructive impacts of sunlight on ...

Summary

The etiology of depression

Depression is a pathological condition that affects many people across the universe. To date, medics are yet to establish the exact causes of depression. It is said that multiple factors that cause depression are involved in many mental disorders. These includes biological differences, brain chemistry, hormones, and genetics. The paper describes the major causes of depression, the cells, tissues and organs affected by depression, and the organ system functions that are affected by the pathologic condition.

Biological differences

Genetic, hormonal, neurological, neuroendocrinological, and immunological mechanisms play a significant role towards the development of depression. Nonetheless, the majority of these factors revolves ...

Discussion

Breast cancer continues to be the primary cause of cancer morbidity and mortality among women. Significant variation is observed in breast cancer survival rates from one geographic area to another (Jemal et al., 2010, Curado, 2011). Interestingly, while the Middle East, along with sub-Saharan Africa and Asian countries have the lowest rates of breast cancer in the world, the incidence has been rapidly increasing over the last twenty years, as it has been with other cancers (Amoori et al., 2014). Some of the factors that play a role in early detection include improved screening practices and education (Curado, 2011). .In ...

Abstract

The immune and nervous systems are two body structures that have different functions. Moreover, most people may not be able to readily identify the and the relationship between these two. While the immune system is responsible in protecting the body from destructive and invading pathogens, the nervous system is tasked to relay information to the brain. This process allows for the proper coordination of the different functions of the body. In general, the concept of the connection between the nervous and the immune systems stems from the theoretical idea of stress. Stress is denoted both as a physiological and ...

Abstract

This paper discusses how exercise stimulates the release of growth hormone. Older people tend to have lower levels of the hormone. As a result, mechanisms have been formulated to help deal with the deficiency which includes inducing the growth hormone into the individual’s body. This, therefore, leads to the discussion of the exact mechanism through which the growth hormone facilitates exercise, maintains growth and repair of worn out muscles or even reverses the aging process among the aged. Also, the functions of IGF-I binding proteins during exercise and its importance in aiding the release of the GH is ...

Abstract

Growth hormone is one of the many hormones released in the human body. This paper discusses the relationship between the growth hormone and exercise. The exact mechanism through which the growth hormone facilitates exercise is discussed in the paper. It is noted that the growth hormone is released rapidly in young children and teenagers but the production slows down with age. Other factors such as gender, adipose and diet also play a huge role in regulating the release of the growth hormone. For that reason, it is recommended that the aged people should exercise more frequently to induce the ...

Approximately 3 percent to 10 percent of pregnancies within studied populations are affected by gestational diabetes, a condition involving elevated blood sugar levels in women previously not diagnosed with diabetes (Metzger et al., 2007; Moore & et al, 2005; Schneider, 2014). Due to changes in diagnostic criteria, the prevalence of gestational diabetes may occur in as many as 20 percent of pregnancies (Kim, 2010).
Insulin receptors begin to dysfunction secondary to factors related to pregnancy and blood glucose levels rise. There are relatively few symptoms of gestational diabetes and screening of pregnant women is the most effective method of diagnosis. ...

Abstract

The positive effect of high intensity cardio exercise on body fat is well known. The paper looks into the greater impact on body composition due to those high-intensity exercises. Regular cardio is known to increase both aerobic and anaerobic fitness. Until recently, it was thought that low intensity exercises like walking or slow jogging burn more fat and high intensity workouts like running or high intensity aerobics are meant more for cardiovascular fitness and not for burning fat. However, now the evidence from scientific studies and controlled trials is showing that high intensity cardio may actually burn faster and ...

Introduction

There was a time when women, in order to rid themselves of unwanted pregnancy, would risk their lives by inserting coat hangers or knitting needles into their vagina to abort a child. Abortion, which refers to the process of terminating pregnancy after a woman has conceived, is debated largely even today. One better way to avoid the circumstances that lead to abortion is to go for birth control options that inhibit pregnancy in the first place. Today, there are a number of birth control options available including contraceptive pill, patch, vaginal ring, IUD, diaphragm, male condom, female condom and implant, but the most ...

The Process of Spermatogenesis in the Male Testis

Spermatogenesis is an intricate process that involves mitotic cell division, meiosis, and its process. The regulation of spermatogenesis involves the endocrine and the paracrine mechanisms. The spermatogenesis endocrine stimulation involves the follicle stimulating hormones (FSH) and the luteinizing hormone. The luteinizing hormone acts through the intermediary testosterone that is produced by the leydig cells in the testis. A male fertility requires the production by the testis with large number of normal spermatozoa by spermatogenesis process. There are three major steps subdivided in the process; the mitosis, meiosis, and the transformation of the round spermatid. The multiplication of spermatogonia is ...

Use of Restriction Enzymes in Pharmaceuticals
Restriction enzyme, which is also referred to as restriction endonuclease, is a class of enzyme that is helpful in cutting DNA at restriction sites. Restriction sites are particular recognition nucleotide sequences on double stranded DNA having the length of 4-5 base pairs. Restriction enzymes are also known deoxyribonucleases (DNases). Presently, there are four different types of restriction enzymes:
- Type I enzymes that are “classical” in nature, e.g. EcoKI, EcoBI, and EcoR124;
- Type II enzymes that are “orthodox” in nature, e.g. EcoRI, HindIII, EcoRV;
- Type III enzymes ...

Abstract

Autism is not a physical disability. It is a neural development disorder that falls under the umbrella of developmental disorders. There are several other types of autism spectrum disorder, or ASD, including Asperger’s syndrome, Rett syndrome, and childhood disintegrative disorder, among others. Children with autism display various attributes that affect the developmental aspect of an individual such as the behavioral, communication, and social interaction. This becomes apparent during childhood and continues on to adulthood. Properly diagnosing whether a newborn baby is autistic is difficult during the infancy period because the behavioral symptoms associated with it have not yet fully been developed ...

Impact of Noise Pollution on Mental Health

Introduction
Noise is increasingly becoming a major threat to both human and animal life. In last few decades, noise pollution has increased considerably in every urban area with an ever-increasing population and heavy load of traffic on roads.

Introduction

The term lipids is used to refer to a group of organic compounds that are naturally occurring and that are all soluble in non-organic solvents such as benzene , chloroform, acetone and ether but not soluble in water. The later characteristic means that lipids can also be defined as amphiphilic or hydrophobic small modules. This amphophilic nature of lipids essentially allows them to be able to form structures such as liposome’s, vesicles or membranes when subjected to aqueous environments. The biological lipids mainly originate from two major build-blocks or biochemical sub-units: isoprene and ketoacyl groups. Another distinct characteristic of lipids ...

Introduction

Water is a naturally occurring resource. Its importance cannot be emphasized any more than it already has over the past few years of the new millennia. This coupled with the changing climatic trends that result in the short-circuiting of the hydrological cycle, has brought water policies to the forefront of consideration of governments and international organizations. Like every other demographically limited resource, the availability of water is scarce and growing scarcer by the day. However, different regions have different priorities when regarding water resource management. This is brought about by the disparity in economic capacity that brings about the wide ...

Introduction

Body cells normally grow, divide, and die in a systematic manner. During adulthood, most cells divide to repair injuries or to replace the dying (worn-out) cells. Some cells, however, grow out of control. These cells are referred to as the cancer cells. Instead of dying, the cancer cells grow out of control (abnormally) and form new abnormal cells. Besides, the cancer cells can invade normal tissues. In most cases, the cancer cells form a mass of body cells that are malignant and have no physiological function, usually called the tumors. When they get into the blood stream or the lymph vessels, ...

Abortion

Abortion can be defined as the termination of a pregnancy by removal of the embryo or fetus from the uterus before it is due (Bacon, 2004, p. 2). Abortion can be induced or spontaneous. A spontaneous abortion is usually known as a miscarriage. Induced abortion is an easy procedure that can easily pass for the easiest procedures in the medical field. However, the procedure has cost so many lives, and severe consequences such as damage to the uterus, leading to barrenness. This happens if the procedure is carried out by an unskilled person.

Many people opt for an induced abortion due ...

Efficacy of Ondansetron in oral rehydration

Introduction
Ondansetron is a drug that blocks actions of chemicals within the body that can trigger an episode of vomiting or diarrhea (Freedman, 2016). The body has a system of regulating itself and fighting any harmful condition or substance. The medulla oblongata is responsible for the regulation of involuntary actions such as breathing, vomiting, thirst and heart rate. This part of the brain can detect various chemicals and hormones within the blood. When a potentially toxic substance gets detected, the chemoreceptor trigger zone initiates the vomiting process.
Ondansetron prevents nausea and vomiting caused by surgical activities or cancer medication. ...

Depression (deprimo - «pressure", "suppress") is a mental disorder characterized by "depressive triad": depressed mood and loss of ability to experience pleasure (anhedonia), disturbances of thinking (negative judgments, pessimistic view of what is happening, etc.), motor inhibition. Depressive patients have low self-esteem; they lose their interest in life and daily activities. In some cases, a person suffering from this disorder may start to abuse alcohol or other psychotropic substances.
Biological reasons for depression are associated with genetic predispositions, biochemical causes, etc. Heritability can explain depression. Results of several twin studies showed that heritability of major depression is approximately ...

General features of melatonin

Melatonin is a hormone, which is thought to play an important role in daily processes of humans’ lives, being secreted by the pineal gland, which is an endocrine gland, located in the middle of the brain. After its discovery the first function (which later gave the name to this hormone) was the ability of this hormone to lighten one’s skin color. This experiment was conducted on frogs, however even nowadays everybody knows that our sunbathing results in suntan due to activity of melatonin. This is a so-called skin-darkening effect of melatonin.
First discoveries of this hormone were done ...
