ANATOMY

Detailed explanation-1: -The skin possesses many sensory receptors in the epidermis, dermis, and hypodermis, which allows for discrimination of touch such as pressure differences (light vs. deep). Other qualities of the external world assessed by skin sensory receptors includes temperature, pain, and itch.

Detailed explanation-2: -Pacinian receptors detect pressure and vibration by being compressed which stimulates their internal dendrites. There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkel’s disks and Meissner’s corpuscles.

Detailed explanation-3: -Tactile Stimuli. Tactile stimuli are external forces in physical contact with the skin that give rise to the sensations of touch, pressure, flutter, or vibration.

Detailed explanation-4: -A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system.

Detailed explanation-5: -Skin receptors (known as mechanoreceptors and cutaneous receptors also) enable us to detect the location of the stimulus when an outer force (i.e., touch, pressure, stretching, vibration, motion) applied and deformed our skin (Table 3.4) Each of the receptors is sensitive a specific type of stimulus.
