What is the deepest layer of skin next to the dermis called?

The deepest layer of the skin next to the dermis is referred to as the Basal Layer, also known as the stratum basale. This layer is critical because it contains the basal cells, which are actively dividing and responsible for producing new skin cells. As these cells divide, they push older cells upward towards the surface of the skin, allowing for continuous regeneration and repair.

In addition to its role in skin renewal, the basal layer is also where melanocytes are found, which produce melanin, the pigment responsible for skin color. This layer is essential for maintaining skin health and protecting underlying tissues, as it forms a barrier against external elements.

The other options refer to different layers or structures in the skin. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells that protect against environmental damage. The stratum Malpighii is not a commonly used term today, but it historically referred to the combined layers of the epidermis like the basal and spinous layers. The term epidermis refers to the entire outer layer of skin, which includes multiple layers, not just the deepest one next to the dermis. Understanding the distinct functions and positions of these layers helps clarify the role of the basal
