How do adrenal hormones influence gastrointestinal function?
Thanks
Answers:
Adrenal hormones such as epinephrine will slow down the GI tract. Peristaltic movements slow, stomach secretions lessen, the anal sphincters close off, etc.
Think about if you're within a fight or flight situation. If you're running, your body will need all the vivacity it can get in its muscles to help you run, instead of expending joie de vivre on GI function.
Acetylcholine is the neurotransmitter that speeds up GI function (but it's not really an adrenal hormone). Source(s): Pharmacy student
Out of the three main types of hormones released by the adrenal gland, the catecholamines (epinephrine/norepinephrine) increase sympathetic stimulation, so they'd lead to a decrease surrounded by GI motility (you don't want to be using energy to digest food when you are fighting/running away from big scary animals trying to eat you). Glucocorticoids (cortisol) would increase tart secretion in the stomach, and mineralocorticoids (aldosterone) wouldn't really do much of anything in the GI system at all (its effect is to increase sodium and fluid retention contained by the kidneys).
