The Relationship between the Adrenal Glands and the Autonomi
The Adrenal medulla secretes two hormones, they are the epinephrine (adrenaline) and norepinephrine (noradrenaline). Since the adrenal medulla and the autonomic nervous system are so intertwined the medullary cells are actually modified post- ganglionic neurons. Preganglionic autonomic nerve fibers lead to them from the central nervous system.
The effects that occur when sympathetic nerve fibers stimulate their effectors are very simi
