THE THYROID GLAND A large secretor do up of two lobes joined by a alternate mass (isthmus), located at the base of the throat. Composed of knife grammatical constructions called follicles. The function of the thyroid gland gland is to take iodine, install in many foods, and convert it into thyroid hormones: Thyroxine (T4) and deoxythymidine monophosphate (T3). thyroidal carrells are the only cells in the organic structure that are adequate to(p) to absorb Iodine. These cells combine iodine and the aminic acid tyrosine to ramp up T3 and T4. THE HORMONES T3 and T4 controls the rate of glucose being burn or oxidized and converted to eubstance heat or chemic energy (bodys major metabolic hormone). Every cell in the body depends upon thyroid hormones for regulation of their metabolism. Thyroxine (T4) is the major hormone secreted by the thyroid follicles. Most Trii odothyronine (T3) is organise at the buns tissue by the conversion from Thyroxine. (All cells need constant sum up of chemical energy so therefore all body cells are tar lends). CHEMICAL material body Each hormone is constructed from two conjugate tyrosine amino acids with destined Iodine atoms. T3 has 3 iodine atoms and T4 has four.
REGULATION-NEGATIVE FEEDBACK The thyroid gland is at a lower place control of pituitary gland. When the level of hormones(T3 and T4) drops also low, the pituitary produces thyroid stimulating hormone (TSH). TSH past stim ulates the thyroid gland to produce more hor! mones. The thyroid gland makes and secretes the hormones, which raises their level in the blood. The pituitary gland senses this and decreases the levels of TSH hormone. DISORDERS HYPERTHYROIDISM An overproduction of t3 and t4. many things can cause this such as gravid`s disease or a damaged thyroid gland. grave disease is when your immune system mistakenly attacks your thyroid...If you desire to get a full essay, order it on our website:
