Which glands secrete mucus into the vagina and labia minora?

• A. Bartholin's glands
• B. Skene's glands
• C. Montgomery glands
• D. Uterine glands

Answer: (A)

Lubrication of the vaginal vestibule is provided by the greater vestibular glands, located in the posterior part of the labia majora and whose ducts open into the vestibule near the vaginal opening. Their mucus secretion moistens the vaginal intro and surrounding labial mucosa, especially during arousal, helping reduce friction. The other glands have different locations and roles: Skene's glands are paraurethral glands around the urethral opening and secrete into the urethra; Montgomery glands are sebaceous glands around the areola of the breast; uterine glands are within the uterus and secrete mucus there. Thus, the glands that secrete mucus into the vagina and labia minora are Bartholin's glands.
