A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. Normally there are four main types in glabrous skin: Pacinian corpuscles, Meissner's corpuscles, Merkel's discs, and Ruffini endings.
Physiology of Baroreceptors. Baroreceptors are mechanoreceptors located in the carotid sinus and in the aortic arch. Their function is to sense pressure changes by responding to change in the tension of the arterial wall. The baroreflex mechanism is a fast response to changes in blood pressure. sudden increase in blood pressure stretches the baroreceptors and the increased firing results in the vasomotor center inhibiting sympathetic drive and increasing vagal tone on the SA node of the heart. The SA node is slowed by the acetylcholine and heart rate slows to correct the increase in pressure.
