PUDIC NERVE 203 



Branches. From the plexus : 



Muscular to levator ani, coccygeus, and external sphincter. 



Cutaneous to the lower part of the buttock by means of a 

 branch called the perforating cutaneous nerve. 



The Pudic nerve arises from the second, third, and fourth 

 sacral nerves ; it passes through the sacro-sciatic foramen, and 

 lies on the spine of the ischium on the inner side of the internal 

 pudic artery. It then enters the perineum with the artery 

 through the small sacro-sciatic foramen. The nerve supplies 

 all the muscles and skin of the perineum.
