Document Summary
Secretes hormones into the bloodstream to maintain homeostasis. Endocrine cells - located in a gland. Target cells - have hormone receptors and allow change to happen. Anterior lobe - acth, tsh, gh, prl, fsh, lh, msh. Hypothalamus - adh, oxt & regulatory hormones. Thyroid gland - t3, t4, (calcitonin) ct. Cortex - cortisol, corticosterone, aldosterone & androgens. It integrates neural and endocrine activities via 3 mechanisms. Secretes regulatory hormones - going to impact the pit gland. Contains autonomic nervous system centers - going to affect the adrenal medulla. Stimulates the production of thyroid hormones t3 & t4. Fsh - targets follicular cells in the ovaries and testes. Stimulates follicle development and estrogen secretion and sperm maturation. Fh - targets follicular cells and interstitial cells. Stimulates ovulation, corpus luteum formation and progesterone secretion. Gh - targets all cells in the body. Stimulates growth, protein synthesis, lipid mobilization and catabolism. Stimulates increased melanin production in the epidermis.
