The two most important hormones of the adrenal medulla are the catecholamines. epinephrine and norepinephrine (Figure 1). The synthesis pathway for. norepinephrine is identical to that used by adrenergic neurons. However, the. adrenal medulla expresses an additional enzyme, phenylethanolamine-N-methyl-.
The adrenal medulla is the core of the adrenal glands , and is surrounded by the adrenal cortex. In the fifth week of human fetal development, neuroblast cells migrate from the neural crest to form the sympathetic chain and preaortic ganglia. The cells migrate a second time to the adrenal medulla. The adrenal medulla produces Catecholamines, derived from the amino acid tyrosine. These water-soluble hormones are the major hormones underlying the fight-or-flight response. The adrenal medulla secretes approximately 20% norepinephrine and 80% epinephrine.
