Question:

It is false that the epidermis

(a) is highly vascular

(b) contains melanin and keratin

(d) gives rise to sebaceous and sweat glands.

The Epidermis

The epidermis is the outer layer of the skin, overlaying the dermis. The epidermis acts as a protective covering, preventing pathogens such as bacteria and viruses from entering the body, and prevents excess water loss through the skin.
