Which glands are located on each side of the urethral meatus in the vestibule?

Skene's glands, also known as the paraurethral glands, are located on either side of the urethral meatus in the vestibule. These glands serve an important role in female anatomy as they contribute to lubrication during sexual arousal and may play a role in the female orgasm. The fluid produced by Skene's glands can also provide some antibacterial properties, protecting the urinary tract.

In contrast, Bartholin's glands, while related to female reproductive anatomy, are situated at the posterior vestibule and are primarily responsible for producing lubricating secretions during sexual arousal. Smith's glands and Halstead's glands are not recognized anatomical structures in this context, as they do not pertain to the female urogenital system. Thus, Skene's glands are the correct focus for their specific location and function adjacent to the urethral meatus.
