Superior gluteus nerve

from Wikipedia, the free encyclopedia

The glut nerve (a) eus superior ( Latin , "upper gluteal nerve") is a nerve of the lumbar and cross plexus ( plexus lumbosacralis ). In animals it is called the gluteus cranialis nerve ("anterior croup nerve").

The cells of origin ( root cells ) of the nerve are located in the lumbar and cross parts of the spinal cord from the fourth lumbar vertebra (L4) to the first cross vertebra (S1).

In humans, the nerve runs together with the artery and vein of the same name through the suprapiriforme foramen (upper / cranial part of the ischial hole). In domestic animals, the nerve descends from the lumbosacral trunk , a common origin for the superior gluteus, inferior gluteus and sciatic nerve . This leaves the pelvic cavity through the greater sciatic foramen .

The superior gluteus nerve almost exclusively contains motor nerve fibers and innervates three skeletal muscles of the hip region : gluteus medius , gluteus minimus (in animals: deep gluteus ) and tensor fasciae latae .

Improper intramuscular injection into the buttocks can injure the upper gluteal nerve.
