THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Introduction. Mechanoreceptors are a type of somatosensory receptors which relay extracellular stimulus to intracellular signal transduction through mechanically gated ion channels. The external stimuli are usually in the form of touch, pressure, stretching, sound waves, and motion.

Detailed explanation-2: -Mechanoreceptors. Mechanoreceptors detect stimuli such as touch, pressure, vibration, and sound from the external and internal environments. They contain primary sensory neurons that respond to changes in mechanical displacement, usually in a localized region at the tip of a sensory dendrite.

Detailed explanation-3: -Mechanoreceptors, also called mechanoceptors, are specialised neurons that respond to mechanical pressure and distortion. They are innervated with sensory neurons that convert mechanical pressure into electrical impulses that are transmitted to the central nervous system.

Detailed explanation-4: -Four major types of encapsulated mechanoreceptors are specialized to provide information to the central nervous system about touch, pressure, vibration, and cutaneous tension: Meissner’s corpuscles, Pacinian corpuscles, Merkel’s disks, and Ruffini’s corpuscles (Figure 9.3 and Table 9.1).
