Multiple Choice

The role of ceruminous glands is to:

produce sebum to lubricate the skin

secrete sweat to regulate body temperature

generate melanin to protect against UV radiation

produce earwax to protect the ear canal

Verified step by step guidance

Understand the location and function of ceruminous glands: These specialized sweat glands are located in the external ear canal and are responsible for producing cerumen, commonly known as earwax.

Recognize the purpose of cerumen: Earwax serves as a protective barrier, trapping dust, debris, and microorganisms to prevent them from entering deeper into the ear canal.

Differentiate ceruminous glands from other glands: Unlike sebaceous glands that produce sebum to lubricate the skin or eccrine sweat glands that regulate body temperature, ceruminous glands have a distinct role in ear protection.

Clarify the role of melanin: Melanin is produced by melanocytes in the skin to protect against UV radiation, which is unrelated to the function of ceruminous glands.

Conclude that the correct answer is 'produce earwax to protect the ear canal,' as this aligns with the anatomical and physiological role of ceruminous glands.
