Final answer:
The statement that the adrenal medulla is composed of nervous tissue yet secretes neurohormones is true. It facilitates the body's stress response by producing epinephrine and norepinephrine.
Step-by-step explanation:
The statement is true: neuroendocrine glands such as the adrenal medulla are composed of nervous tissue but secrete chemicals known as neurohormones. The adrenal medulla operates at the intersection of the nervous system and the endocrine system. It is made up of specialized cells called chromaffin cells that derive from nervous tissue. These cells act like neurons, but instead of transmitting impulses, they release neurohormones into the bloodstream. The main hormones produced by the adrenal medulla are epinephrine and norepinephrine, which are classified as catecholamines and are involved in the body's stress response by providing bursts of energy.
