Document Summary
Site of release and site of action: neurotransmitter site of action is very close and a hormone: site of release and site of action are far apart *biggest difference. Hormones can have many sites of action. Neurotransmitter actions are usually short lived compared to hormones. Hypothalamus is the controller of hormone release releases (cid:1445)releasing hormones(cid:1446) First step for other hormones to be released. Anterior pituitary gland is the master gland and releases tropic hormones that go to targets the body (tropic hormones) The targets are organs (with glands) that also release hormones. Posterior pituitary -- hormones synthesized in the hypothalamus. Organizational effects - when a hormone causes a change that primes the body for some later event. Activation effect - when a hormone elicits a behavioural or physiological event now. Male birds sing to attract the female the mechanistic explanation to this behaviour is the male"s higher vocal centre is 5 times larger than the female"s hvc.
