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 mainly secretes epinephrine (more commonly known as adrenaline), norepinephrine, and small amount of dopamine. Epinephrine and norepinephrine are released from the adrenal medulla in response to short term stress. These two hormones are catecholamines. Composed mainly of hormone-producing chromaffin cells, the adrenal medulla is the principal site of the conversion of the amino acid tyrosine into the catecholamines adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine.
