What is the function of the sebaceous gland?
To secrete cerumen, or earwax
To produce hair growth
To produce sebum or oil
To excrete perspiration, or sweat
Correct Answer : C
Sebaceous glands are microscopic glands in the skin that secrete an oily or waxy substance called sebum into the hair follicles or onto the skin surface.
Sebum lubricates and protects the skin and hair from drying out and from infections caused by bacteria or fungi. Sebum also contributes to body odour.
A. To secrete cerumen or earwax. This statement is wrong because cerumen is produced by specialized sweat glands in the ear canal, not by sebaceous glands. B. To produce hair growth.
This statement is wrong because hair growth is determined by the activity of hair follicles, not by sebaceous glands. Sebaceous glands only deposit sebum on the hairs and bring it to the skin's surface.
D. To excrete perspiration or sweat.
This statement is wrong because perspiration is produced by sweat glands, not by sebaceous glands. Sweat glands are different from sebaceous glands in their structure, location and function. Sweat glands help regulate body temperature and eliminate waste products through the skin.
