Practice Question
What do ceruminous glands secrete?
Answer Choices:
Correct Answer:
Ear wax.
Rationale:
👂Ceruminous glands are modified apocrine sweat glands located in the external auditory canal.
👂They secrete cerumen (ear wax), a mixture of lipids, long-chain fatty acids, and desquamated cells.
👂Cerumen protects the canal by trapping debris, providing antimicrobial activity, and lubricating the skin to prevent dryness.
👂Its slightly acidic pH and hydrophobic nature help discourage bacterial and fungal growth.
👂The amount and type of cerumen can vary with genetics and environment, but its core protective function is consistent.
