The chemoreceptors for the reflexes that stimulate sympathetic activity and epinephrine secretion in response to hypoglycemia are located in the carotid and aortic bodies.

Question

Quizplus · Accepted Answer

The chemoreceptors in the carotid and aortic bodies primarily respond to changes in blood oxygen, carbon dioxide, and pH levels, not to hypoglycemia. The detection of hypoglycemia and the subsequent stimulation of sympathetic activity and epinephrine secretion are primarily mediated by glucose sensors in the pancreas and the brain.
