Answer to Question 1

Ans:
C

Feedback:

The stratum germinativum, or stratum basale, consists of a single layer of basal cells that are attached to the basal lamina. The basal cells, which are columnar, undergo mitosis to produce new keratinocytes that move toward the skin surface to replace cells lost during normal skin shedding. Keratinization does not originate in the dermis or stratum granulosum, and the basal cells of the epidermis do not migrate to the surface.

Answer to Question 2

Ans:
B

Feedback:

Toeing-in, regardless of staging, requires some form of intervention, most commonly braces or casts. Treatment is not noted to include surgery, and spontaneous resolution is not common.
