In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis.Symptoms may include pain, loss of motor control, and sensory deficits.The sacral plexus lies on the back of the pelvis in front of the piriformis muscle and the pelvic fascia.The superior gluteal artery and vein run between the lumbosacral trunk and the first sacral nerve, and the inferior gluteal artery and vein between the second and third sacral nerves.All the nerves entering the plexus, with the exception of the third sacral, split into ventral and dorsal divisions, and the nerves arising from these are as follows of the table below: Adductor magnus (medial part, Tib) This article incorporates text in the public domain from page 957 of the 20th edition of Gray's Anatomy (1918)
