Essays on Muscle Tissue

For the comfort and high standard of living, the humanity is paying the price – its health. It is difficult to argue with that, especially now, when the official WHO data is given: fifty percent of earthlings suffer from overweight. And no matter how we tried to convince ourselves and others that the whole thing is only a slow metabolism, the fact remains – there are practically no fat people in the countries with a low standard of living. This means that the main cause of obesity is still overeating. However, nutritionists believe that people do not gain weight as much ...

Based on the initial symptoms, the patient most likely suffers from hypothyroidism or low thyroid hormone disorder. Further clinical tests and an examination of the family’s medical history reveals that the particular disorder could be Hashimoto’s disease; also called Hashimoto thyroiditis. Hashimoto thyroiditis is classified as an autoimmune disease. In autoimmune disease, one's immune system attacks the body’s tissue specifically the thyroid gland (Skugor & Wilder, 2006, p.2). By attacking the thyroid gland, the disease reduces the gland’s ability to produce thyroid hormones of substantial quantity. This condition leads to hypothyroidism. Thyroid hormone deficiency presents with ...

The following essay is going to review advantages and disadvantage of pre-workout compounds and anabolic-androgenic steroids (AAS) and their effect on athlete health. Pre-workout compounds and AAS are considered to be 2 major enhancers of athlete`s performance in short- and long-term respectively. Among large number of pre-work out compounds like NO-Explode (BSN), The Curse (Cobra Labs), Assault (MuslePharm), C4 (Cellucor), Jack3d is considered to be the most powerful pre-workout compound to be ever created. The difference between old and new mix of Jack3d (produced since 2012) is that older version of Jack3d included DMAA (1,3-dimethylamylamine). Just like ...

Rhabdomyolysis

Introduction In normal conditions, muscles grow when certain activities cause the muscle fibers to become damaged and then subsequently regrown and developed through a series of cellular process. This activity occurs during the body is at rest. In other words, the continuous breakdown is normal for growing muscles as it allows them to become bigger through the introduction of myrofibrils, or muscle fibers. However, there is a condition when the muscle fibers break down rapidly due to a number of reasons, and then they do not regrow at a corresponding rate. This condition is known in medical circles as ...

Inadequate insulin secretion leads to a rise in blood glucose levels, which is the main characteristics of diabetes. By the time a diagnosis of type 2 diabetes (T2D) is made, 70 to 80% of beta cell mass loss is already done. Loss of beta cells of pancreas occurs gradually, beginning much before the diagnosis of diabetes is made and continuing even after that. For this reason, the damage becomes irreversible (Cnop, 2005).

Skeletal benefits of vitamin D are well known and described widely in the literature, but in recent years, research has shown that Vitamin D seems to aid in ...

- The human nervous system may be categorized into two divisions namely PNS and CNS. The nervous system has three broad functions which include sensing changes in the body as well as within outside environment; interpreting changes as well as establishing suitable response depending on reflexes, current conditions and experiences; and responding to interpretation through initiating action by glandular secretions (Paxinos, 2010). The PNS link the spinal cord and brain with receptors, glands, and muscles.

- Nerve impulse or action potential is an electrical signal which travels along the neuron resulting from entry of ions into neuron and altering ...

In the human beings, the muscular system brings about movement of their entire body (Carter, 2007). There are about 700 muscles that are attached to the bones of the skeleton system, which comprise of almost half of the body weight of an individual (Clarke, 1996). Further, every muscle is, however, a discrete organ that is made up of the skeleton muscle tissue, tendons, nerves, and the blood vessels. Additionally, muscle tissue is present inside the heart, blood vessels, and the digestive organs. There are three major types of muscle tissues namely Visceral Muscle, which is found inside the intestine, stomach, ...

Question 1

The cerebellum is an essential part of the neuromuscular system in that it plays major roles in the timing of muscular activities and the smooth progression of one muscular movement to the next. The summary of how this is done is that it sequences all the muscular activities necessary for a particular movement, and then makes corrective adjustments as necessary when the movement is being executed so that they conform to the motor impulses being generated by the cerebral cortex and other significant parts of the central nervous system (Ganong, 2005). For instance, for an individual holding a cup and ...

“Certain Type of Fat Could Help Humans Lose Weight”

1. Briefly state the main idea of this article. The article published Oct 2 2013 in Science Daily refers to research conducted recently by nutrition scientists at Texas Tech University, and published in The Journal of Lipid Research. According to the article, the findings of the research “could lead to supplements and a diet regime that will increase metabolism and decrease muscle fatigue in humans.” The findings of the research could allow us to take a supplement to encourage human muscles to burn off surplus energy instead of storing it as fat. The researchers noted that whilst that ability to ...

Patient Three

A 30-year-old woman presented to her Family Medicine physician with complaints of increased sweating (even in relatively cool surroundings), diarrhea, unexplained weight loss, insomnia, and feelings of anxiety. Her friends also had asked her whether she was worried, because her eyes seemed bulging out always. Her physician shook her hand and told her that everything would be okay. He noticed that her hand was shaking and her palm felt sweaty. Vital signs included a heart rate of 168, and blood pressure of 149/92. Her EKG was normal other than the rapid heart rate, and showed normally narrow QRS complexes. A ...

On the fifth of July 1996 the first cloned sheep was born, they called her ‘Dolly’ and she sparked off one of the hottest debates of the twentieth century, the debate over the nature of and consequences of cloning a human being, thus starting the idea of bio-ethics. Science furthering the lifespan of the human race has been at the core of scientific research since the dawn of time, organ donor-ship, organ transplants, advances in medical technology, like in vitro fertilisation, what seemed like science fiction to people of the past are now commonplace, everyday affair for those living ...

The debate regarding performance enhancing drugs such as anabolic steroids has been a heated one, as high-profile instances of "juicing" have led to professional sports celebrities like Barry Bonds and Sammy Sosa gaining unfair advantages over other players. Olympic drug scandals occur nearly every competition, and horror stories about steroid abuse and addiction clutter the news. However, despite the extremely negative press that exists regarding the use of anabolic steroids, there are some benefits to using it, and with safe use, steroids can provide ethical advantages to many athletes and people of all ages in all walks of life. In ...
