Mnemonic for innervation of baroreceptors

Many at times students come across questions in USMLE regarding baroreceptors, their location and their innervation. At times questions focus on the loss of innervation and its resultant effects on the body and its very critical to remember which baroreceptors are innervated by which nerves.

Arterial baroreceptors are located in the aortic arch and the carotid sinuses of the right and left carotid arteries. The baroreceptors found within the aortic arch monitor the pressure of blood delivered to the systemic circuit, and the baroreceptors within the carotid arteries monitor the pressure of the blood being delivered to the brain.


The glossopharyngeal nerves transmits impulses from carotid sinuses whilst the vagus nerves transmits impulses from the aortic arch. A simple mnemonic to remember this is:
