Here's why:
* Location: Merkel cells reside within the basal layer of the epidermis, which is the deepest layer of the skin.
* Function: They are specialized sensory cells that detect light touch and pressure. They work in conjunction with nerve endings, forming Merkel cell-neurite complexes.
* Mechanism: When pressure is applied, the Merkel cell releases neurotransmitters that stimulate the associated nerve ending, sending signals to the brain for interpretation.
Note: While other cells reside in the basal layer, like keratinocytes, they primarily function in skin regeneration and not as mechanoreceptors.
