An epithelial cell in the thyroid gland, called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine residues in thyroglobulin molecules, inside the follicle cell. (www.vivo.colostate.edu/hbooks/pathphys/endocrine/thyroid/chem.html)…

Almost all cells of the human body are target by thyroid hormones. Activity on targeted tissues can be altered by blood levels, meaning onset, durations and half-life of the hormone. Thyroid hormones can affect an individual by means of affecting how one metabolizes. For example if ones metabolism decreases they may gain more weight.…
The thymus gland is a gland that forms part of the immune system. It is situated in the upper part of the chest, behind the breastbone, and is made up of two lobes that join in front of the trachea. Each lobe is made of lymphoid tissue, consisting of tightly packed white blood cells and fat. The thymus enlarges from about the 12th week of gestation until puberty, when it begins to shrink.…
The thyroid is a small butterfly-shaped organ located in the throat just above the collarbone. It is one of the most important, and most overlooked, organs in the body. In fact, the thyroid is largely responsible for the body's temperature, appetite, metabolism, heart health, and regulation of the brain, kidneys, reproductive system, etc. In other words, when the thyroid is working you never notice it is there, but when something goes wrong, things can spin out of control really fast. Many people who suffer from weight problems, sleeplessness, fatigue, depression, etc. are actually feeling the effects of thyroid problems.…
The class viewed sheep brains, human models, and demo cats. The class separated into groups and began locating the listed endocrine glands on the human models. There were also human brain models to identify specific glands. Once finished, the major endocrine glands of the sheep brain were viewed. The sheep brain is quite similar to the human brain except for proportion. Although, the orientation of the human brain is superior to inferior whereas the sheep brain is anterior to posterior. The demo cats were very interesting. One of the cats viewed was pregnant. The placenta was obvious. It surrounded each kitten individually. Although the cat and human are very different externally, both have similar internal composition. Majority of the endocrine glands are placed in similar positions. Some endocrine glands are totally different when it comes to placement. For example, the adrenal glands, in the human models, sit on top of the kidneys. Opposed to the cat, the adrenal glands sit to the side of the kidneys. The thymus is anterior to the heart in the demo cat. The thymus is posterior to the heart in the human models. Although different, the studied examples of endocrine glands were all very similar in structure and…
Hypothyroidism is a medical condition which the thyroid gland doesn’t produce enough of the important hormones. The two main hormones which are produced in the thyroid gland thyroxine (T-4) and tiiodothyronine (T-3). These hormones are what fight of fats and carbohydrates, help control your body temperature, heart rate, and regulate the release of protein. The thyroid also produces hormones calcitonin which regulates calcium being released into the blood. (Clinic, 2010)…
