Thyroid Disease

The thyroid gland glandal secretory organ is rigid on the trend set off of the neck below the thyroid gristle (Adams apple). The secretor poses thyroid internal secretions, which regulate body metabolism. Thyroid internal secretions be important in regulating body energy, the bodys use of another(prenominal) hormones and vitamins, and the growth and emergence of body tissues. Diseases of the thyroid gland dope result in either proceeds of too more than (overactive thyroid malady or hyperthyroidism), too little (underactive thyroid disease or hypothyroidism) thyroid hormone, thyroid nodules, and/or goiter. every(prenominal) types of thyroid problems in women are much more viridity than thyroid problems in men. Production of thyroid hormones: The process of hormone synthesis begins in a part of the brain called the hypothalamus. The hypothalamus releases thyrotropin-releasing hormone (TRH). The TRH travels by means of the venous plexus located in the pituitar y wheat to the pituitary gland, also in the brain. In response, the pituitary gland then releases thyroid-stimulating hormone ( thyroid-stimulating hormone) into the railroad line line. The TSH travels to the thyroid gland and stimulates the thyroid to produce the both thyroid hormones, L-thyroxine (T4) and triiodothyronine (T3). The thyroid gland also needs adequate amounts of dietary iodine to be able to produce T4 and T3.

Regulation of thyroid hormone end product: To prevent the overproduction or underproduction of thyroid hormones, the pituitary gland can aesthesis how much hormone is in the blood and ad just the production of hormones accordingly.! For example, when there is too much thyroid hormone in the blood, TRH and TSH production are both decreased. The middle effect of this is to decrease the amount of TSH released from the pituitary gland and to reduce production of thyroid hormones from the thyroid gland to prepare the amount of thyroid hormone in the blood to normal. Defects in these regulatory pathways may result in hypothyroidism (underactive thyroid problem) or hyperthyroidism (overactive thyroid problem)....If you want to hold out a full essay, order it on our website: OrderCustomPaper.com
