    The question:

    The adrenal glands are in part controlled by the sympathetic and parasympathetic branches of the autonomic nervous system. Name the hormones involved in this regulation and the functions of each

    I know that the sympathetic is adrenaline and noradrenaline. I can't find what the parasympathetic hormones are. I know they slow heart rate and reduce blood pressure and induce a state of relaxation.

    I can find the functions of the hormones if someone could point me in the direction of where to find out which hormones I need to write about!

    To find the answer, we must find out the anatomy of the adrenal glands which will give you the innervation, and then look for the physiology which will give you what they secret and the effects.
    The adrenal glands are divided into medulla (inner part) and cortex (outer part).
    The innervation of the medulla derives from the sympathetic ganglions. In fact the adrenal medulla cells are considered modified sympathetic postganglionic neurons (McCorryl,. 2007). The medulla produces epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine. "Norepinephrine causes a marked increase in peripheral vascular resistance as a result of ...
