Thyroxine

triglycerides to fatty acids. The balance between insulin and glucagon results with undisturbed metabolism and provides a stable inner metabolic homeostasis across the body. The hormones, T3, also called triiodothyronine, and its prohormone, T4, also called thyroxine, are hormones produced by the thyroid…

of the neck just below our Adam’s apple, this gland produces thyroxine and triiodothyronine. Whenever a patient is diagnosed with HT-H they may ask “What is that?” According to Judith Simms, and Rebecca. J. Frey, HT-H is a condition in which a person’s thyroid gland isn’t producing enough hormone, and it may be caused by an autoimmune disorder. HT-H develops when the thyroid gland lacks to produce thyroxine as the body needs. Thyroxine regulates the heart rate, physical growth, digestion. A…

Diganostic criteria for hypothyroidism is based on symptoms and the results of blood tests that measure the level of TSH and the level of the thyroid hormone thyroxine. The high level of TSH and low level of thyroid hormones as known as free T4 level indicate an underactive thyroid hormone or hypothyroidism. When the thyroxine level is low, the pituitary gland produces TSH to stimulate thyroid gland to produce more thyroid hormone. TSH tests play an important role in managing hypothyroidism.…

Hyperthyroidism diagnosis can be completed by blood tests, by testing the level of TSH and thyroxine in the blood. Thus, an increase of thyroxine and a decrease of TSH show an overactive thyroid. A number of disorders of thyroid function have been found to be caused by mutations in the TSHR gene, which encodes the TSH receptor protein. Graves' disease, an autoimmune disorder is the main cause of hyperthyroidism producing antibodies by the immune system arouse the thyroid to produce too much T4.…

Hyperthyroidism The thyroid stimulating hormone is secreted by the pituitary gland. Hyperthyroidism is a condition in which the thyroid gland is over producing and makes an excessive amount of thyroid hormone. The thyroid gland is and organ that is located in the front of the neck and releases hormones that control your metabolism. Symptoms: When the thyroid gland is over active (hyperthyroidism) the body process will speed up and you may experience nervousness, anxiety, and rapid heartbeat,…

consists of two lobes joined by an isthmus, or middle section. It is an important gland in that it regulates metabolism and growth and affects almost every organ of the body. The thyroid uses iodine in the food we eat to produce vital hormones like thyroxine or T4 and triiodothyronine, T3, both of which regulate the speed at which your cells metabolic processes function. The thyroid itself is regulated by the pituitary gland and hypothalamus and functions on a feedback system. Much like a…

T4 and T3 are the hormones that are generally secreted by the thyroid gland. T4 is known as thyroxine and T3 is known as triiodothyronine. Since our bodies only need a small amount of T3, it’s not as a concern, but the hormone is still needed. When a newborn experiences cretinism it may result in underdevelopment or abnormal development of the thyroid…

Cretinism: also known as congenital hypothyroidism effects about 1 in 4000 babies. Cretinism is a situation induced by an insufficiency of thyroid hormone at birth and during minority, as a ensue of abnormal evolution of the thyroid gland. The thyroid gland becomes unbalanced or defective often due to an iodine imperfection. If untreated, can result in mild to severe impairment of both physical and mental growth and development. Cretinism can also cause mental deterioration, swelling of the…

pregnancy. To qualify as obese, one must weigh twenty percent more than their weight that corresponds to their height. Obesity can be caused by a endogenous hormone. For example, hypothyroidism is one. Hypothyroidism is when TSH is increased, and thyroxine is decreased. There are two types of obesity, idiopathic and endogenous. Idiopathic is caused by a person's lifestyle, while endogenous is caused by a gland. Obese children have more skin problems than healthy children. Obese children run…

specific follicle cells of the thyroid gland by the oxidative condensation of its biological precursors, monoiodotyrosine and diiodotyrosine, and is then subsequently secreted into the bloodstream. The remaining 80% is produced from the conversion of thyroxine (T4) into triiodothyronine (T3), by removal of the iodine atom from the carbon atom number five of the outer ring of T4, as seen in Fig. 2. T4 is deiodinated in peripheral tissues to form T3 due to T3’s greater potency on target tissues…
