In female anatomy, the vestibular bulbs, bulbs of the vestibule or clitoral bulbs are two elongated masses of erectile tissue typically described as being situated on either side of the vaginal opening. They are united to each other in front by a narrow median band.
The artery of bulb of vestibule (artery of the vestibule bulb) is a branch of the internal pudendal artery. It supplies the vestibular bulbs and thus only exist in females. [ 1 ]
The bulb of penis is the proximal/posterior bulged [1] end of the (unpaired median) corpus spongiosum penis. Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. [2] It is covered by the bulbospongiosus. Proximally/posteriorly, the bulb of penis extends towards the perineal body. The bulb ...
Together with the vestibular bulbs, they form the clitoral root. The crura are attached to the pubic arch, and are adjacent to the vestibular bulbs. The crura flank the urethra, urethral sponge, and vagina and extend back toward the pubis. Each clitoral crus connects to the rami of the pubis and the ischium.
The Bartholin's glands (named after Caspar Bartholin the Younger; also called Bartholin glands or greater vestibular glands) are two pea-sized compound alveolar glands [2] located slightly posterior and to the left and right of the opening of the vagina. [3] They secrete mucus to lubricate the vagina. [3] They are homologous to bulbourethral ...
Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
They have a slightly different origin, insertion and function in males and females. In males, these muscles cover the bulb of the penis, while in females, they cover the vestibular bulbs. In both sexes, they are innervated by the deep or muscular branch of the perineal nerve, which is a branch of the pudendal nerve.
The artery to the bulb of the vestibule originates from the perineal artery and pierces the perineal membrane to travel towards the vestibule of the vagina. [4] The deep and dorsal artery of clitoris are the two terminal branches of the internal pudendal artery which pierce the perineal membrane to supply the clitoris. [5]
