Document Summary

Learning objectives for homeostasis part 2: objective: describe the functional organization of the hypothalamic pituitary axis (pp. The sensor y input information goes to the cns (neuroendocrine origins of signals), which leads to the hypothalamus. Hypothalamus releases hypothalamic hormones (releasing factors) to the anterior pituitary as first target or to posterior pituitary . The post pituitary produces oxytocin which targets smooth muscle and mammary glands, it also produces vasopressin which targets arterioles. The ant pituitary makes: corticotropin (acth) targets the adrenal cortex which then produces cortisol, corticosterone and aldosterone. These target many tissues: thyrotropin targets the thyroid which produces thyroxine (t4) and triiodithyroxine (t3). Hypothalamus also produces oxytocin and vasopressin (adh) released to the posterior pituitary whre they are stored. The hypothalamus secretes hormones to the anterior pituitary which releases hormones to a target endocrine organ. The organ releases its own hormone to feed back to either the hypothalamus or the anterior pituitary.
