Detailed explanation-1: -Mammalian Merkel cells are descended from the epidermal lineage. Merkel cells are specialized cells in the skin that are important for proper neural encoding of light touch stimuli. Conflicting evidence suggests that these cells are lineally descended from either the skin or the neural crest.
Detailed explanation-2: -Merkel cells associated with slowly adapting type 1 (SA1) A-low-threshold mechanoreceptor (A-LTMRs) afferents neurons form the Merkel complex. They are present within the basal layer of the epidermis in both hairy and glabrous skin. (B, C).
Detailed explanation-3: -Merkel cells. Merkel cells are postmitotic cells scattered throughout the epidermis of vertebrates and constitute 0.2–0.5% of epidermal cells. Merkel cells represent part of the affector limb in cutaneous slowly adapting type-1 (SA1) mechanoreceptors and are therefore particularly concerned with touch sensation.
