What term describes a secretion of the sebaceous glands?

Perspiration
Serum
Cerumen
Sebum

The correct answer is: Sebum

The secretion of the sebaceous glands is referred to as sebum. Sebaceous glands are small oil-producing glands located in the skin. They play a crucial role in maintaining the health and hydration of the skin and hair by producing this oily substance. Sebum acts as a natural moisturizer, helping to prevent dryness and providing a barrier that protects the skin from external factors such as pathogens and environmental damage. It also contributes to the skin's overall appearance and can influence conditions such as acne when produced in excess or when glands become clogged. The other options refer to different substances: perspiration is the fluid secreted by sweat glands, serum is the clear liquid that separates from blood when it clots, and cerumen refers to earwax, which is secreted by glands in the ear canal.
