Cole Trickle has bad acne. This affects the oil glands attached to his hair follicles, which are ______ glands and are examples of which type of gland?
ceruminous; holocrine
sebaceous; merocrine
sweat glands; apocrine
sebaceous; holocrine
mammary glands; apocrine
The Correct Answer is D
A. ceruminous; holocrine
Ceruminous glands are found in the ear canal and produce earwax (cerumen). They are modified apocrine glands, not related to acne.
B. sebaceous; merocrine
Sebaceous glands are correct, but they are holocrine, not merocrine. Merocrine glands release their product via exocytosis without cell destruction.
C. sweat glands; apocrine
Apocrine sweat glands produce a different type of secretion and are more associated with body odor in the axillary/genital areas. They’re not oil glands and not typically involved in acne.
D. sebaceous; holocrine
Sebaceous glands secrete oily sebum into hair follicles and are holocrine in nature, meaning the entire cell disintegrates to release the product-often leading to clogged pores and acne.
E. mammary glands; apocrine
Mammary glands are modified apocrine glands but are responsible for milk production, not involved in acne or oil secretion.

Correct Answer is C
Explanation
A. edema

B. vasodilation of blood vessels
Vasodilation increases blood flow to bring immune cells and nutrients, but does not physically isolate the injury.
C. formation of a clot
A blood clot forms a physical barrier that helps prevent the spread of pathogens and walls off the injury.
