Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones. Hyperthyroidism causes a rapid heart rate, elevated blood pressure and tremors. Other symptoms include increased nervousness, inability to concentrate, weakness, restlessness, difficulty sleeping, frequent bowel movements, weight loss and irregular

In order to evaluate thyroid function and diagnose thyroid diseases such as hyperthyroidism or hypothyroidism, the free thyroxine (free T4) lab test is performed usually after discovering that the thyroid stimulating hormone (TSH) level is abnormal (Porth C 2014 p.1288)

TSH not only stimulates the thyroid gland to churn out more hormones. If in excess, can cause overwhelming cell growth and division to result in goiter.

The thyroid is a part of the endocrine system. The thyroid produces two hormones that affect metabolism, heart function and brain development. The hormones also helps regulate body temperature, weight and skin dryness. The two hormones that the thyroid secrets is triiodothyronine (T3) and thyroxine (T4). Thyroid-Stimulation hormone (TSH) is secreated by the pituitary gland, also part of the endocrine system, regulates the production on thyroid hormoes. If thyroid hormones are low the pituitart gland releases more TSH and if the thyroid hormones are hign less TSH is released. If someone is has Hashimoto’s disease the function of the thyroid and pituitary gland is affected and starts to decrease the thyroid hormones in the body and causes the pituitary gland to release more TSH into the

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine

The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes

Graves’ Disease is diagnosed based on a series of blood tests, in addition to displaying several symptoms. Laboratory work seeks to discover elevated levels of serum thyroxine (T4) and triiodothyronine (T3) associated with TSH [2]. T3 and T4 help control the body’s metabolism and are needed for normal growth of the developing brain. TSH or thyroid-stimulating hormone is necessary to check for thyroid gland problems and how significant the issue is. One can be diagnosed from a small risk case, in which it can be controlled by medication, to a big risk bringing thyroid cancer into consideration.

Thyroxine (T4) is produced by the thyroid gland in the throat. Because of its many

The thyroid regulates your metabolism, your appetite, muscle function, blood pressure, heart rate, among other things. And a way that it interacts with the pituitary is a good example of a negative feedback loop, a method of communication that's common all over the body and especially in the endocrine system. Basically, the pituitary is like the thyroid's thermostat. It can read how much thyroid hormone is in your blood stream and when its levels are low, it spits out a tiny bit of thyroid stimulating hormone, or TSH, which travels to the thyroid. The thyroid, in turn, secretes thyroid hormone, which boosts our metabolism, and that increase in metabolism tells the pituitary to stop sending out TSH. So the effect of the pituitary secretion is

The thyroid gland which belongs in the (Endocrine System) is a butterfly-shaped gland that’s located in the front of the neck. The main purpose of the thyroid is that it runs the body metabolism. Hypothyroidism an autoimmune disease what I was diagnosis with some years ago. Now, the autoimmune disease occur when one’s body produces antibody that attacks its own tissue and this can includes the thyroid gland.

The thyroid gland is a butterfly shaped endocrine gland that is normally located in the lower front of the neck behind the adam 's apple and along the windpipe. The thyroid gland is very rich with blood vessels. The main purpose of the thyroid is to make, store, and release thyroid hormones into the blood which is then carried to every tissue in the body. How the works is that when you acquired iodine from the food you eat. Some food has a good source of iodine in it, for example iodine is in most foods like milk, salt, bread, etc. The Thyroid gland then takes the right amount of iodine out of your blood and uses it to make two different types of thyroid hormones. The thyroid hormones produced can be either of two different types, either thyroxine or triiodothyronine. According to the article You and Your Hormones, thyroxine is the inactive form of the thyroid hormone while Triiodothyronine is the active form of thyroid the hormone. Thyroid hormones help the body use energy, stay warm and keep the essential body organs working, for example the heart, brain, muscles and other organs. But the thyroid gland influences most of all the metabolic process in the body.

There can be several internal abnormalities with the thyroid gland and other systems of the body such as the immune system that can show signs of this condition. A few of those internal irregularities are to the actual gland’s size, surface,

The thyroid gland, a butterfly-shaped organ, located in the middle of the lower neck synthesizes and releases thyroid hormones. These vital hormones affect multiple body functions such as the brain development, nervous system functions, metabolism, cardiac system functions, body temperature, cholesterol levels and menstrual cycles. Not only is the thyroid gland one of the largest organs of the endocrine system, the gland is the only organ in the human body that absorbs iodine necessary to produce the thyroid hormones. The most common issues with the thyroid gland are when the gland is overactive, hyperthyroidism and underactive, hypothyroidism. ( 1, 2 )
