Document Summary

Part of the brain function in a neuroendocrine capacity. Links the endocrine and the nervous systems. Connected to pituitary gland by portal vessels. 2 modes of action (fig 45. 15 and fig 45. 14) Stimulates or inhibits release of specific hormones from ap. Axons extend into the posterior pituitary (pp) Release hormone -> stimulate hormone -> end hormone. Stores and secretes: hormones produced in hypothalamus. Oxytocin > milk, contractions, care, (pair) bonding. Endocrine gland hormones released into the blood. Every ap hormone is controlled by at least one rh. Trophic hormones (signal other endocrine tissue, middleman, from ap to somewhere else) Nontropic hormones (direct physiological effects, signal an organ to get a physiological response) Tropic and nontropic hormones (single endocrine tissues, but also signal nonendocrine tissues) Term for sets of hormones from hypothalamus, ap, target endocrine gland, and finally a response in target tissue (four main steps) Hypothalamus > ap > other gland > target tissue > response.
