Final answer:
Sebaceous glands are primarily located in the dermis layer of the skin, closely associated with hair follicles, and they produce sebum to lubricate and protect the skin and hair.
Step-by-step explanation:
Sebaceous glands are specialized oil glands that are primarily found in the dermis layer of the skin. These glands are closely associated with hair follicles and produce an oily substance known as sebum, which helps to lubricate and waterproof the skin and hair. The sebum produced also plays a role in inhibiting the growth of certain bacteria on the skin's surface, hence providing mild antibacterial protection.
The primary location of sebaceous glands is within the dermis, but they can also be found in certain areas without hair such as the eyelids, nipples, and genitals. They are not active during childhood and usually become more active after puberty, responding to hormone levels in the body. The correct answer to the question would be C. In the dermis.
Functions of the Sebaceous Glands:
Lubricating and waterproofing the skin and hair
Generating sebum to keep the stratum corneum pliable
Providing antibacterial properties to protect the skin surface
