No. The cells of stratum corneum contain keratinthat prevents water evaporation
The epidermal cells that are actively mitotic and replace superficial cells are found in the stratum basale, also known as the basal layer or stratum germinativum.
The ridges of the stratum germinativum are called dermal papillae. These structures help anchor the epidermis to the dermis and play a role in increasing surface area for nutrient exchange between the layers.
Translucent cells containing keratin are called squamous cells. These cells are flat and scale-like in shape, and they form the outermost layer of the skin.
The epidermal layer just interior to the stratum granulosum is the stratum spinosum. This layer is composed of living keratinocytes that help provide strength and structure to the skin. The stratum spinosum is important for cell turnover and the production of keratin.
No. The Stratum Granulosum is deteriorating organelles. The Stratum Basale, or Stratum Germinativum, is the "Germinating layer". The most rapid cell division occurs here, of course, because it's closest to the vascular dermis.
The epidermal layer. (below that is the acellular dermal layer)
It takes anywhere from 15 to 30 days for cells to migrate from the stratum germinativum to the stratum corneum.
stratum germinativum is also know as stratum basale
stratum basale
Keratinocytes of the stratum corneum contain large amounts of keratin protein.
you answer it
They are called corns.
Stratum Germinativum
Yes, the stratum corneum is notable for its keratin content.

The layer of the epidermis that is constantly undergoing mitosis is called the stratum basale, also known as the basal layer. This layer is responsible for producing new skin cells that eventually move up through the other layers of the epidermis.
