Question

A splinter penetrated into the skin of the sole of the foot, almost to the papillary region of the dermis. Which layer of the epidermis would be the final layer injured?

Answer 1

Answer: Stratum Basale

Explanation:

The two main layers composed in the skin are the epidermis and the dermis.

The epidermis is the superficial layer of the skin and is composed of four to five layers depending on the location of the body.

These layers are; stratum basale, stratum spinosum, stratum granulosum, stratum corneum and a fifth superficial layer located only on the palms of the hand and soles of the feet, called stratum lucidum.

The epidermic layers ranges from deep to superficial, with the deepest and fifth layer being "stratum basale" also called the "stratum germinativum" which is just located above the layers of the dermis. And in this case would be the fifth layer the splinter would penetrate and then injure.
