INTERNAL PUDENDAL ARTERY

 

 

ORIGIN: Anterior division of internal iliac artery

 

COURSE/DISTRIBUTION: Arises from the radial artery below the elbow and Course in male:

The artery is bigger in male than female and it springs from the anterior division as one of its terminal branches and proceeds to the lower part of the greater sciatic foramen below the piriformis. It then passes through the foramen to reach the gluteal region, snubs that region by passing behind the ischial spine to re-enter the pelvic cavity accompanied by the pudendal nerve and the nerve to obturator internus. It then enters the pudendal canal within the ischiorectal fossa in the obturator fascia. It passes above the inferior fascia of urogenital diaphragm and ends behind the inferior pubic ligament by dividing into its two terminal branches- the deep and dorsal arteries of penis or clitoris. It is main artery of supply to the male and female perineum

 

BRANCHES:

  • Perineal artery

 

Male

  • Urethral artery
  • Deep artery of the penis
  • Dorsal artery of penis

 

Female
