Question

Quizplus · Accepted Answer

The adrenal medulla is comprised of modified sympathetic neurons which secrete hormones that stimulate the “fight or flight” response. These hormones include primarily epinephrine (adrenaline) and norepinephrine (noradrenaline), which are both excitatory hormones that increase heart rate, blood pressure, and metabolism. Acetylcholine is a neurotransmitter that is primarily released by the parasympathetic nervous system, not the adrenal medulla. ADH (antidiuretic hormone) and aldosterone are hormones secreted by the posterior pituitary and adrenal cortex, respectively, and are not related to the functions of the adrenal medulla.
