list the major endocrine glands

pituitary, thyroid, uterus, testicles, adrenals, and pancreas

what are the reasons for using hormonal therapy in veterinary medicine

correct deficiency and obtain desired effect

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


in the body


external

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

GnRH is classified as a/an___

gonadotropin

Hormonal products with "gest" in their name are classified as___
