Answer
The baroreceptors of the carotid sinus and of the aortic arch are sensitive to changes in blood pressure.
Work Step by Step
These baroreceptors are mechanoreceptors that are sensitive to changes in stress and strain in the blood vessel walls caused by blood pressure variations. The responses of stretch-sensitive ion channels to the firing of the mechanoreceptors result in changes in permeabilities to calcium and sodium cations. This leads eventually to the generation of action potentials and afferent signals
