Describe the inner sides of the labia majora.

• A. Smooth and hairless with sweat glands
• B. Smooth skin with hair follicles only
• C. Hairy and pigmented with sebaceous glands
• D. Thick folds of skin extending from pubis to anus

Answer: (A)

The inner surfaces of the labia majora are smooth and hairless and contain sweat glands. This contrasts with the outer surface, which is hairy and bears sebaceous glands. The hairless inner aspect helps with lubrication and reduced friction as the labia majora border the vestibule, while sweat glands contribute to skin health and moisture. The other descriptions describe hair-bearing skin, or the general structure of the labia majora rather than the specific inner surface.
