what are the three types of stimuli that trigger endocrine glands to make and release hormone?
humoral, neural, and hormonal
humoral stimuli is a hormone release caused by ________ levels of critical ________ or _________
altered; ions or nutrients (simplest)
hormones can alter the activity of target cells with ____________ ___________ for them
what must the target cell must have in order to bind to the hormone?
the target cell response depends on hormone __________ levels, number of ___________, and __________ of the binding (hormone and receptor)
blood; receptors; strength
