Dorsal artery of the penis
Encyclopedia
The Dorsal Artery of the Penis is a branch of the internal pudendal artery
which ascends between the crus penis and the pubic symphysis
, and, piercing the inferior fascia of the urogenital diaphragm
, passes between the two layers of the suspensory ligament of the penis
, and runs forward on the dorsum of the penis
to the glans
, where it divides into two branches, which supply the glans and prepuce
.
On the penis, it lies between the dorsal nerve
and deep dorsal vein
, the former being on its lateral side.
It supplies the integument and fibrous sheath of the corpus cavernosum penis
, sending branches through the sheath to anastomose with the deep artery of the penis
.
Internal pudendal artery
The internal pudendal artery is an artery that branches off the internal iliac artery, providing blood to the external genitalia.The internal pudendal artery is the terminal branch of the anterior trunk of the internal iliac artery...

Pubic symphysis
The pubic symphysis or symphysis pubis is the midline cartilaginous joint uniting the superior rami of the left and right pubic bones. It is located anterior to the urinary bladder and superior to the external genitalia; for females it is above the vulva and for males it is above the penis...

Dorsal nerve of the penis
The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the...

Deep dorsal vein of the penis
The deep dorsal vein of the penis lies beneath the deep fascia of the penis; it receives the blood from the glans penis and corpora cavernosa penis and courses backward in the middle line between the dorsal arteries; near the root of the penis it passes between the two parts of the suspensory...
