Explanation:
Detailed explanation-1: -Merkel cells are rare epidermal cells whose function in the skin is still debated. These cells localize to highly touch-sensitive areas of vertebrate epithelia, including palatine ridges, touch domes and finger tips.
Detailed explanation-2: -Merkel cells function as type 1 mechano-receptors and can sense light touches. They are part of the tactile-end organs in the skin, which include Merkel discs, Pacinian corpuscles, Meissner’s corpuscles, and Ruffini endings [30].
Detailed explanation-3: -In the skin, Merkel cells (blue) detect light touch and transmit those signals to sensory neurons (red), which relay the signals to the brain.
