Document Summary

+ other areas of the ccn (eg. neurodevelopment and immunity) Similar hormones (eg. sex hormones) have similar structure and specific receptors. Hypothalamus releases ghrh signals anterior pituitary gland release gh liver, muscle, and bone. Hypothalamus stimulates posterior pituitary gland releases oxytocin from neurons breasts. Caused by stimulation of nipple, results in milk ejection from the mammary glands. Calcium: high calcium stimulates thyroid gland releases ct (calcitonin) bones take up calcium, low calcium stimulates parathyroid gland releases pth (parathyroid hormone) intestine and kidneys reabsorb calcium, bones release calcium. Connecting the nervous system and the endocrine system: Some nerves release hormones directly into the bloodstream (neurohormones) All primary, and secondary endocrine glands and tissue are innervated by neurons in the autonomic ns, nerve signals can modulate hormone secretion. Neurons in the cns and pns have receptors for many hormones (eg. insulin, estrogen) Broken into anterior and posterior: anterior: releases hormones (gh) after stimulated from neurons in the hypothalamus.
