Characteristics of the epidermis

• A. Contains melanin
• B. Distinctive stratified
• C. Sebaceous glands
• D. Contains melanin, distinctive stratified, sebaceous glands

Answer: (D)

The epidermis is a stratified squamous epithelium, meaning it’s made up of multiple layers of flattened cells that form a protective barrier. It also contains melanin-producing cells (melanocytes) in this layer, so melanin is a true characteristic of the epidermis and helps determine skin color and UV protection.

Sebaceous glands, on the other hand, are not part of the epidermis. They reside in the dermis and secrete sebum into hair follicles. So while the epidermis is described by its layered, keratinized structure and presence of pigment-producing cells, it does not include sebaceous glands.

In summary, melanin presence and the distinctive stratified nature are correct descriptors of the epidermis; sebaceous glands are located in the underlying dermis.
