Which of the following is produced by ceruminous glands in the integumentary system?
A
Melanin
B
Sweat
C
Cerumen (earwax)
D
Sebum
Verified step by step guidance1
Understand the role of ceruminous glands: These are specialized sweat glands located in the external auditory canal of the integumentary system. Their primary function is to produce cerumen, commonly known as earwax.
Review the options provided: Melanin, sweat, cerumen (earwax), and sebum. Each of these substances is produced by different structures or glands in the body.
Clarify the function of each option: Melanin is produced by melanocytes in the skin and is responsible for pigmentation. Sweat is produced by sweat glands (eccrine and apocrine) to regulate body temperature. Sebum is produced by sebaceous glands to lubricate and protect the skin.
Identify the correct match: Ceruminous glands specifically produce cerumen (earwax), which helps protect the ear canal by trapping debris and providing antimicrobial properties.
Conclude that cerumen (earwax) is the correct answer based on the anatomical function of ceruminous glands in the integumentary system.
