stimulation of hormone synthesis and release Flashcards
what is hormone release regulated by
endocrine reflexes
what types of stimuli can initiate hormone release
hormonal, humoral, or nervous stimuli
what is hormonal stimulation
the release of another hormone that triggers release of the hormone
what is humoral stimulation
when changes in level of nutrient or ion in the blood triggers release of the hormone
what is nervous system stimulation
stimulation by the nervous system (neuron) triggers release of the hormone
what is the first step in hormonal stimulation
anterior pituitary releases thyroid stimulating hormone (TSH)
what is the second step in hormonal stimulation
TSH stimulates thyroid gland to release thyroid hormone TH
what is the first step in humoral stimulation
blood glucose levels rise
what is the 2nd step in humoral stimulation
increased blood glucose stimulates pancreas to release insulin
what is the 1st step in nervous system stimulation
sympathetic division (fight or flight) is activated
what is the 2nd step in nervous system stimulation
sympathetic preganglionic axons stimulate adrenal medulla to release epinephrine and norepinephrine
