The Area Where the Epidermis and the Dermis Meet Is

Multiple Choice

The area where the epidermis and the dermis meet is highly folded so that the epidermis "fits" into the dermis. What do you think is the function of this highly folded area?

A) Because the epidermis needs to send signals to the dermis, the highly folded area increases the surface area and hence the amount of signals that can reach the dermis.
B) Because the dermis needs to send signals to the epidermis, the highly folded area increases the surface area and hence the amount of signals that can reach the epidermis.
C) The epidermis is the outer layer and is under constant physical stress. This highly folded area between the epidermis and the dermis gives the epidermis additional support and protection against abrasive stress.
D) The epidermis needs to obtain melanin, the pigment produced by melanocytes, which are located in the dermis. The highly folded area increases the surface area and hence the amount of melanin that reaches the epidermis.
