Hashimoto’s Thyroiditis, also called Hashimoto’s disease is an autoimmune disease in which the body’s immune system attacks the thyroid gland. It was named for the Japanese surgeon who discovered it in 1912 The thyroid is a small butterfly shaped gland in the front of the neck. The thyroid makes hormones called T3 and T4. These hormones regulate metabolism. The thyroid is controlled by hormones of the pituitary gland, which is also called the “master gland.” It is a pea-sized gland located in the base of the brain which, among others, makes thyroid stimulating hormone, or TSH. TSH stimulates the thyroid to make thyroid hormone. With Hashimoto’s disease, the thyroid cells are damaged resulting in the inability to make enough thyroid

The iodine uptake with hyperthyroidism is greater than normal. This means that the body produces too much thyroid, meaning there is too much

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

Micro-minerals or trace-minerals required by horses include Iodine, Copper, Zinc, manganese and selenium. Horses use Iodine for fetal development and to regulate metabolism. "inadequate iodine intake in pregnancy can cause serious fetal abnormalities. Foals may be born weak, may not suckle or stand. Thyroid glands can be enlarged (goiter) or normal. Rarely, foals are born hairless or may have ruptured extensor tendons and swollen joints. Iodine deficient newborns may be more prone to infections. Iodine deficient mares may or may not have goiter, a longer gestation and retained placentas. Iodine deficiency can be prevented by feeding iodized salt. Goiter is also a sign of too much iodine or iodine toxicity." (arg.gov.sk.ca)

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.

Incidentally, there are actually two compounds made in the thyroid that are called thyroid hormone. The most abundant is T4, also known as thyroxine, which is then converted to T3, or triiodothyronine. T3 is the active form that produces the effects on metabolism.

Iodine's most effective responsibility is within the formation of two thyroid hormones. Such a is thyroxin; which is required with the aid of the hair follicles and sebaceous glands for correct functioning. Thyroxin helps nourish these hair buildings. Iodine deficiencies can show up as premature grey hair, dull hair, and loss hair.

Commonly, problems with the thyroid involve an abnormal production level of these hormones. It is called hyperthyroidism if there the thyroid hormones are overproduced, and this can cause things like Graves’ disease, Toxic adenomas, and subacute thyroiditis (7). Hypothyroidism is the underproduction of the hormones which can be caused by an inflamed thyroid, iodine deficiency, a non-functioning thyroid gland and more. Hypothyroidism is especially dangerous in infants and newborns as the lack of these thyroid hormones can lead to mental retardation and dwarfism (7). However, in humans hypothyroidism can be caused by things such as a pituitary disorder, a defective thyroid or a lack of the gland completely. (7)

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 - The thyroid gland produces hormones which regulate the body's metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance. Its correct functioning depends on having a good supply of iodine from the diet.

The thyroid stimulating hormone receptors are G-protein linked and are found extracellularly in the thyroid glands. When activated, synthesis of hormonally active iodothyronines T3 (triiodothyronine) and T4 (thyroxine) begins (Park and Chatterjee, 2005). This process begins with iodide is transported into the thyroid gland by the sodium iodide symporter found in the membrane of thyroid follicular cells (Park and Chatterjee, 2005). The iodotyrosine residues monoiodotyrosine and diiodotyrosine are then formed through iodine organification where the iodide is oxidised using hydrogen peroxide and then bound to tyrosine in the thyroglobulin (Park and Chatterjee, 2005). The residues then bind together to form the hormonally active iodothyronines aforementioned (Park and Chatterjee, 2005). Many catalytic enzymes mediate this process and are needed to ensure proper thyroid hormone synthesis. Failure in any steps of the synthesis process leads dyshormonogenesis and could be the result of genetic defects. Adequate synthesis of active thyroid hormone is necessary for the regulation of many developmental processes (Richter, C. et al.,

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

The central effects of hyperthyroidism are most pronounced in development. Cerebral circulation and oxygen consumption elevate. "In hyperthyroidism, Beta-adrenergic binding sites in the cerebral cortex increases and gamma-aminobutyric acid (GABA) binding sites are decreases." (Bucurescu,2014). Brain levels of serotonin, 5-hydroxyindoleacetic acid, and substance P are altered. Native pain sensitivity and number of opiate receptors are increases. Thyroid hormones affect myelination, therefore increased levels lead to oxidative damage to the myelin membrane and/or the oligodendroglial cells. The neurological manifestation is primarily due to the effect of thyroid hormones on other neurotransmitters, hormones, and generalized increased basal metabolic rate. Some of the neurological symptoms are:
