Explanation:
Detailed explanation-1: -Merkel cells are touch-sensitive cells that transduce touch via Piezo2 channels. The Merkel cell-neurite complex contains two sensory receptor cell types. Merkel cells and neurons together mediate different aspects of touch responses.
Detailed explanation-2: -Merkel cells, also known as Merkel-Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates.
Detailed explanation-3: -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].
