|
|
|
endogenous hormones are those that are produced___and exogenous hormones come from____ sources
|

|
|
where is the pituitary gland located? what is its function
|
base of the brain ventral to the hypothalamus, primary function is to control activity of other endocrine glands
|
|
|
describe the difference between a negative and positive feedback control mechanism in the endocrine system
|
a negative feedback mechanism occurs when the hypothalamus senses a high level of a specific hormone in the blood and in response reduces the amount of releasing factor (RF) for this hormone. a reduced amount of RF causes a decreased amount of trophic hormone to be produced by the pituitary; this results in decreased production of the hormone by the target organ. a positive feedback mechanism occurs when the hypothalamus senses a low level of the hormone in question and increases its production of RF. increased RF causes an increase in trophic hormone and a resultant increase in activity of the target organ |
