"Germinativum" is another name for the stratum basale, the deepest layer of the epidermis, which is the outer layer of skin in mammals. This layer is responsible for the growth and regeneration of the epidermis. It contains basal cells which constantly divide and differentiate into keratinocytes, the main cell type of the epidermis.
The stratum basale is also home to melanocytes, which produce melanin, the pigment that gives skin its color and protects it from UV radiation.
Here are some key characteristics of the stratum germinativum:
- Cell Division: This layer is where cell division occurs, constantly producing new cells to replace those that are shed from the surface of the skin.
- Melanocytes: These cells are responsible for producing melanin, which helps protect the skin from UV radiation.
- Merkel Cells: These specialized cells are involved in touch sensation.
- Basement Membrane: This thin layer separates the stratum basale from the dermis, the deeper layer of skin.
The stratum basale, or germinativum, is vital for maintaining the integrity and function of the skin. It is constantly working to replace lost cells and protect the body from environmental damage.
