External pudendal artery

from Wikipedia, the free encyclopedia

The external pudendal artery (“external pubic artery”) is an artery in the groin region .

human

The external pudendal artery arises in humans from the external epigastric artery below the inguinal ligament and passes through the cribrosa fascia . There it is divided into two groups:

  • The rami scrotales anteriores ("anterior scrotum branches") or rami labiales anteriores ("anterior labial branches") supply the skin of the scrotum or the outer labia .
  • The rami inguinales (" inguinal branches") supply the skin of the groin region and the inguinal lymph nodes .

Veterinary anatomy

In most other mammals, the external pudendal artery rises together with the epigastric artery caudal from the artery deep femoral - this common vessel master is called celiac pudendoepigastricus referred. The external pudendal artery then passes through the inguinal canal and divides into two main branches:

  • The ramus scrotalis ventralis ("abdominal scrotum branch") or Ramus labialis ventralis ("abdominal branch of the labia") pulls towards the scrotum or the labia. In the case of the mare and cow, it is also known as the caudal mammary artery ("posterior udder artery") because it is the main inflow to the udder .
  • The superficial caudal epigastric artery pulls on the abdominal wall in the direction of the navel .
