half-life
persistence in the blood stream
range from seconds to 30 minutes

cAMP and calcium
how are G proteins activated
when a hormone binds with a membrane-bound receptor
signal amplification
turns one signal molecule into multiple second messenger molecules
close relationship between the hypothalamus and the pituitary gland as an example of the close relationship between the nervous and endocrine systems
the hypothalamus regulates the function of the pituitary gland
differences between the anterior and posterior pituitary, including hormones secreted and respective functions
the anterior pituitary gland secretes a tropic hormone, which travels in the blood to the target endocrine cell
