Apocrine glands:
Are found primarily in the axillary and genital areas
Are endocrine glands
Arise within the hypodermis
Are called oil glands
The Correct Answer is A
A. Are found primarily in the axillary and genital areas: Apocrine glands are sweat glands located in the armpits (axillary) and genital regions. They become active at puberty and secrete a thicker sweat that can cause body odor.
B. Are endocrine glands: Apocrine glands are exocrine glands, not endocrine. They release their secretions onto the skin surface through ducts rather than into the bloodstream.
C. Arise within the hypodermis: Apocrine glands are located in the dermis, not the hypodermis. The hypodermis consists mostly of fat.
D. Are called oil glands: Oil glands (sebaceous glands) produce sebum, while apocrine glands secrete sweat.
