Three Stimuli Triggering Hormone Release
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Endocrine glands release hormones in response to three stimulus types: humoral, from changing fluid composition; hormonal, from another hormone's signal; and neural, direct from the nerves.
Show
Rising blood glucose is a humoral stimulus triggering insulin; TSH triggering thyroid hormone release is hormonal.
Watch for
A gland can respond to more than one stimulus type — the adrenal medulla responds to neural stimuli, unlike most.
