Asplinter 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? granulosum basale lucidum spinosum

In the given case, the stratum basale would be the final layer of the epidermis to get injured.

It is the deepest layer of the five layers of the epidermis, which is the outer covering of the skin in mammals. It is a single layer of cuboidal or columnar basal cells. It is also referred to as stratum germinativum.

The stratum basale is situated just over the papillary layer, which is the thin top layer of the dermis. The papillary layer constitutes blood vessels and connective tissues, which provide nutrients to the epidermis. So, when the splinter penetrates the sole of the foot, that is, almost to the papillary region of the dermis, the basale layer would get injured.

Thus, the correct answer is stratum basale.
