Document Summary
Releases hormones important in protein synthesis, nutrient metabolism, normal growth, mental development in kids and infants (via growth hormone). Influences function of cv, resp. , gi and neuromuscular systems. Regulates basal metabolic rate of all tissues except the brain, anterior pituitary, spleen, lymph nodes, testes and lungs. Basal metabolic rate is the baseline speed that cells perform their function with. Cells bmr can raise by 60%-100% with thyroid hormones. Rapid metabolic rate increases demands of vitamins. Maintains body temperature raising oxidation of energy stores (glucose, fats, proteins) will increase thyroid o2 consumption and body temp. Increases gi motility, appetite and body weight. Increases amount of beta 1 and beta 2 adrenergic receptors and increases affinity to catecholamines. Increases sympathetic activity and leads to increase heart rate and contraction cardiac output and cardiac o2 demands. Thyroid gland has two basic cell types: Secretes calcitonin hormone for calcium balance. Secretes thyroid hormones enzymatic cleavage of one iodine atom.
