Which cells of the adrenal medulla release epinephrine and norepinephrine?
AOxyphil cells
BChromaffin cells
CFollicle cells
DPinealocyte cells
Answer & Solution
Correct answer: B. Chromaffin cells
1. The adrenal medulla is neuroendocrine tissue made of postganglionic sympathetic neurons.
2. Those large, irregularly shaped cells are the chromaffin cells.
3. They release epinephrine and norepinephrine into the systemic circulation, which is why the two count as hormones.
4. Oxyphil cells sit in the parathyroid, follicle cells in the thyroid and pinealocytes in the pineal gland.
