Question

For a cell to move from the stratum germinativum to the stratum corneum takes approximately:

A. 6 weeks
B. 7 days
C. 1 month
D. 14 days

Answer 1

It takes approximately 4 weeks for a cell to move from the stratum germinativum to the stratum corneum.

Step-by-step explanation:

The migration of cells from the stratum germinativum to the stratum corneum takes approximately 4 weeks. The stratum corneum is the most superficial layer of the epidermis and consists of dry, dead cells that are periodically shed and replaced by cells from the underlying layers. This turnover process takes about a month, during which new keratinocytes move up from the stratum basale to the top of the stratum corneum.
