Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a splinter penetrated the skin in to the third epidermal layer of the sole of the foot, what would be the last cell layer damaged?
A
Granulosum
B
Basale
C
Lucidum
D
Spinosum
Explanation: 

Detailed explanation-1: -Stratum basale (innermost layer). As a result, when the splinter entered the skin of the sole of the foot, the stratum basale, which is the innermost epidermal layer, will be the final layer to be injured. Hence, this is the correct option.

Detailed explanation-2: -Skin Thickness Hairless skin found in the palms of the hands and soles of the feet is thickest because the epidermis contains an extra layer, the stratum lucidum.

Detailed explanation-3: -It does not have any blood vessels within it (i.e., it is avascular). Skin that has four layers of cells is referred to as “thin skin.” From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum.
