Corpus: Dorsal artery of penis
1. Definition
The dorsal artery of the penis is a terminal branch of the internal pudendal artery.
2. Anatomy
The dorsal artery of the penis runs between the crus of the penis and the pubic symphysis. It pierces the inferior fascia of the urogenital diaphragm and travels between the two layers of the suspensory ligament of the penis to the dorsal side of the penis. On the dorsal surface, it runs above the corpus cavernosum, situated between the dorsal nerve and the deep dorsal vein of the penis, extending toward the glans penis. There, it divides into two branches that supply the glans and the foreskin. A specific branch, the frenular artery, supplies the frenulum of the foreskin.
Smaller secondary branches form anastomoses with the deep artery of the penis.
3. Function
The dorsal artery of the penis supplies the skin of the penis and the tunica albuginea with arterial blood.
