Explanation:

Question 18

Skin appendages include structures like sweat glands, oil (sebaceous) glands, hair, and nails. The hypodermis (subcutaneous layer) is not an appendage but a layer beneath the dermis, providing insulation and cushioning. So the option that is not a skin appendage is the hypodermis.

The skin typically accounts for about 15% of a person's body weight. This is a standard anatomical fact regarding the skin's contribution to total body mass.

Directional terms: Superficial means closer to the surface, deep means farther from the surface. The hypodermis is located deep to the dermis (part of the skin), so "Deep" describes its location relative to the skin.

Answer:

d. The hypodermis
