The artery to the bulb of the penis (male) or vestibule (female) is a branch of the internal pudendal artery. It differs slightly in males and females.
Artery to the bulb of the penis
-
Origin: internal pudendal artery, distal to the perineal artery1.
- a common penile artery, serving as the origin of this artery (and the dorsal and deep arteries of the penis), has been described2.
- Course: travels alongside the urethra and together these pierce the perineal membrane to enter the corpus spongiosum at its posterolateral border (into the bulb). It supplies cavernous tissue of the corpus spongiosum as it courses towards the glans penis.
- Anastomosis: the terminal branches of the artery form an anastomosis with the dorsal artery of the penis at the level of the glans penis
-
Supply
- membranous urethra and some contribution to the penile urethra
- corpus spongiosum and the bulb of the penis
- bulbourethral glands (of Cowper)
- glans penis (via anastomosis with the dorsal artery of the penis)1,3
Artery to the bulb of the vestibule
Its origin is similar to that of its male homologue. From the internal pudendal artery, it courses towards the vestibule and supplies the bulb of the vestibule and the greater vestibular glands (of Bartholin)1,3,4.
