Ans1: Growth is defined as the increase in size and mass of a particular organism over a period of time. It is measured in terms of biomass (mass of the organic material). An organism grows by mitosis. Growth stops after certain age of the organism. Growth is quantitative and measured by taking the measurement of height, weight, size and shape of body organs like brain, etc . Development is defined as the process of cells differentiation which helps in the development of the body. It adds complexities to the body (such as organ development). Development of the organism is a ...

- The stromal cells that are found in the developing gonads of tetrapods begin from the medulla from the peritoneal wall and the cortex from inter-renal blastema or mesonephric. Hence the gonads have a dual origin. - Spermatogenesis occurs in a syncytial complex because it involves the formation of sperm from undifferentiated cells that are first attached to rachis. Syncytial cell complex or syncytium result when cells with single nuclei fuse to for a cell with nucleus. Syncytial cell complex is vital in oogenesis in that it assists in the differentiation of cells. One other developmental model is vitellogenesis. - ...

Introduction

In the mouse and other mammalian species, the pool of primordial follicles becomes established during fetal or neonatal life (Oktay et al., 1995). Over the mammal’s lifespan, the follicles undergo growth and development, and eventually the initial reserve of follicles begins to diminish during the mammal’s midlife. Briefly, follicular cells move from a primordial phase, in which little DNA synthesis is taking place, to enter a primary and then secondary stage, in which the granulose cells undergo intense proliferation and high levels of DNA synthesis can be observed. Antral and post- ovulation stages follow (Oktay et al., 1995). Folliculogenesis ...

Introduction

Ms. Zona is an 83 – year - old female patient who has been admitted to the hospital for worsening of the pressure ulcers on both of her heels. She has a medical history of type 2 diabetes (T2D).

Her heel ulcers are painful; therefore, she tends to spend most ...
