Stratum basale Definition
It refers to the basal or the deepest of the five layers of the epidermis. It is also known by the names “germative layer” or “basal layer.” Sometimes, it is also referred to as stratum germinativum.
Stratum basale Location
It is situated between myometrium and the stratum spongiosum.
Stratum basale Anatomy
This epidermal layer comprises only one row of cuboidal or columnar epithelial cells. Half of these cells divide constantly and replace the remaining part of the epidermis that is wearing away. The remaining cells differentiate and go to the next epidermal layer to start the process of maturation.
Stratum basale Function
It forms the outer skin covering in animals. The process of cell division (mitosis) occurs in this layer and replenishes the skin cells.
Stratum basale Problems
This layer of the epidermis might be involved in various skin disorders, such as Psoriasis and basal cell tumors.
