Which body part has the thinnest skin?

• A. Back.
• B. Ears.
• C. Scalp.
• D. Soles of the feet.

Answer: (B)

The ears have the thinnest skin compared to the other options listed. This is primarily due to their anatomical structure and the fact that the skin over the ears is quite delicate and less dense. The skin on the ears consists of fewer layers of epidermis, making it thinner than that on the back, scalp, or soles of the feet. In contrast, the skin on the back is thicker to provide protection and support due to its exposure to external elements and its role in movement. The scalp has a thicker dermal layer due to the presence of hair follicles and glands. The soles of the feet possess thickened skin that is specifically adapted to withstand pressure and friction from walking and standing, which is why they have a denser epidermal layer. Thus, the unique characteristics of ear anatomy account for their relatively thin skin.
