GENERAL HISTOLOGY

Detailed explanation-1: -Classification by receptor complexity: Free nerve endings are dendrites whose terminal ends have little or no physical specialization. Encapsulated nerve endings are dendrites whose terminal ends are enclosed in a capsule of connective tissue.

Detailed explanation-2: -The Meissner corpuscles are stimulated by skin motion and are located in the epidermis layer. The Merkel cells are located at the border between the dermis and epidermis and are specialized to detect edges and points.

Detailed explanation-3: -Meissner corpuscles are ellipsoid mechanoreceptors located superficially within the dermal papillae at a depth of approximately 150 micrometers.

Detailed explanation-4: -Meissner’s corpuscles, found in glabrous skin, are rapidly adapting, encapsulated receptors that detect touch, low-frequency vibration, and flutter. Ruffini endings are slowly adapting, encapsulated receptors that detect skin stretch, joint activity, and warmth.
