What skin layer contains Merkel cells?

The skin layer that contains Merkel cells is the stratum germinativum, also known as the basal layer of the epidermis. The stratum germinativum is responsible for the production of new skin cells, as it is the deepest layer of the epidermis. Merkel cells, which are specialized sensory cells, are located within this layer and play a crucial role in the sensation of touch. They are connected to nerve endings, making them essential for the tactile sense.

This layer's unique structure, which includes not only Merkel cells but also keratinocytes that are actively dividing, allows for the continuous renewal of the skin. Understanding the role of Merkel cells within the stratum germinativum helps highlight the importance of this layer not just for skin health and repair but also for sensory function.
