Question

The only layer of the epidermis that contains stem cells capable of continued cell division is the
A)stratum spinosum
B)stratum basale
C)stratum corneum
D)stratum granulosum
E)stratum lucidum

Accepted Answer

The stratum basale, also known as the basal cell layer, contains stem cells capable of continued cell division, which allows for the ongoing regeneration of new skin cells. This layer is located at the bottom of the epidermis and is in contact with the basement membrane. The other layers of the epidermis do not contain stem cells that can continue to divide.
