Bulb of the vestibule
Bulb of the vestibule is a part of the female reproductive system that is located within the vulva, specifically on either side of the vaginal orifice. It is a structure that is homologous to the corpus spongiosum in the male, which is the tissue that surrounds the urethra.
Anatomy[edit | edit source]
The bulb of the vestibule is an erectile tissue structure. It is covered by the bulbospongiosus muscle, which contributes to the constriction of the vaginal orifice. The bulb is internally divided into two parts by a median septum. It is also connected to the greater vestibular glands, also known as Bartholin's glands.
Function[edit | edit source]
The primary function of the bulb of the vestibule is to contribute to sexual arousal and orgasm in females. During sexual arousal, the bulb of the vestibule becomes engorged with blood, causing the vulva to expand outward. This process aids in sexual stimulation and can contribute to the achievement of orgasm.
Clinical significance[edit | edit source]
Understanding the anatomy and function of the bulb of the vestibule is important in various medical fields, including gynecology, urology, and sexology. It can be involved in certain medical conditions, such as vulvodynia, a chronic pain condition that affects the vulvar area.
