Question

Which of the following layers of the epidermis is responsible for cell division and replacement?
A) stratum spinosum
B) stratum basale
C) stratum corneum
D) stratum granulosum

Accepted Answer

The stratum basale, also known as the basal cell layer, is the innermost layer of the epidermis and is responsible for cell division and replacement. This layer contains stem cells that constantly divide and differentiate into new keratinocytes, which then migrate towards the surface and replace older cells that have been shed.
