|
|
what hormone deals with the reproductive processes
|
follicle stimulating hormone, luteinizing hormone, testosterone, estrogen, progesterone
|
|
|
what hormone deals with homeostatic maintenance of cardiac output and PB during stress
|
norepinephrine, epinephrine, angiotensin II
|
|
|
what is the primary homeostatic mechanism within the endocrine system
|
the negative feedback
|
|
|
how are hormones released in the negative feedback system
|
in short burst when needed
|
|
|
when is the negative feedback control of hormone synthesis activated
|
a low plasma concentration of a circulating hormone stimulates one or more endocrine organs to secrete activating hormones
|
|
|
what is the end result of the negative feedback control system
|
once the optimal concentration of circulating hormone is reached, this suppresses further secretion of activating hormone until the cycle repeats itself
|
|
|
What does positive feedback do to hormones effect
|
it amplifies a hormone effect; the original stimulus is promoted
|
|
|
What is required to shut of the positive feedback cycle
|
an outside factor (like giving birth)
|
|
|
The response counteracts the stimulus shutting off the response loop
|
negative feedback
|
|
|
the response reinforces the stimulus sending the parameter father from the set point
|
positive feedback
|
|
|
an example is stimulatory input from the sympathetic nervous system on the adrenal medulla causes epinephrine and norepinephrine secretion
|
neural control
|
|
|
example: blood Ca++ concentration regulates parathyroid hormone (PTH) release from the parathyroid glands
|
chemical control
|
