What is a lumbosacral plexus?

lumbosacral plexus is a range of nerves with branches near the lumbar or middle spine and sacral or lower part of the spine. It is normally located towards the front of the body, usually consisting of lumbar and sacral nerves. Coccygeal nerve is usually part of the lumbosacral plexus; These nerves are often referred to as lumbar nerves and are usually found in a muscle called PSOAS Major, which sits in front of the spinal cords called vertebrae. The nerves that come in this area generally form a formula similar to a branch in the lower body and also into the feet.

One of the three parts of the total structure, the lumbar plexus often includes parts of other main spinal nerves and divide into different main nerves of the abdomen. This area also results in femoral nerves, which usually spread into the feet and down. Other branches go to the thigh and reproductive organs, while some are also associated with muscliks such as a quadrilateral in the leg. Another branch is usually associated with the knee structure.

lumbar nerves division usually begin in nerve structures called ganglia on the sides of the vertebrae. Every nervous division of the lumbosacral plexus, from top to bottom, is often greater than that above it. The first three usually separate and are re -connected by structures called anastomotic loops; The lumbar plexus also consists of the fourth and fifth nerves. These usually combine and create another part called Sakral plexus.

Sacral plexus is usually placed from where the main nerve of the foot is called seating, branches. Usually the largest in the body, the seating nerve can provide a feeling for the entire surface of the skin of the foot and attach to the muscles from thigh to leg. Even lower in the abdomen is the pudendal plexus, which usually pzadky near the rectum and part of the lower pelvis. The branches of these nerve structures also often travel to the back of the thigh.

abnormalities of lumbosacral plexus may occur in humans and other animals and sometimes present at birth or r rThey have entered throughout their lives. Malformed spinal cords and arthritis can affect nerves. Injuries, infections and degenerative diseases can also lead to conditions in which the nerves of lumbosacral plexus are at risk. These problems can affect feel, mobility and other biological functions.
