The adrenal medulla consists of irregularly shaped cells grouped around blood vessels. These cells are intimately connected with the sympathetic division of the autonomic nervous system (ANS). In fact, these adrenal medullary cells are modified postganglionic neurons, and preganglionic autonomic nerve fibers lead to them directly from the central nervous system.Adrenal medulla increases available energy; heart rate; and metabolism.

Famous quotes containing the word basic:
“... in Northern Ireland, if you don’t have basic Christianity, rather than merely religion, all you get out of the experience of living is bitterness.”
—Bernadette Devlin (b. 1947)
“Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy.”

“When you realize how hard it is to know the truth about yourself, you understand that even the most exhaustive and well-meaning autobiography, determined to tell the truth, represents, at best, a guess. There have been times in my life when I felt incredibly happy. Life was full. I seemed productive. Then I thought,”Am I really happy or am I merely masking a deep depression with frantic activity?” If I don’t know such basic things about myself, who does?”
—Phyllis Rose (b. 1942)
