The word for a place on the body where there is a dense network of peripheral nerves that come together in one spot is a plexus. Plexuses are found throughout the body, and they serve to connect the peripheral nerves to the central nervous system. Some of the most well-known plexuses include the brachial plexus, which is located in the neck and shoulders, and the lumbar plexus, which is located in the lower back. Plexuses are essential for the proper functioning of the nervous system, and damage to a plexus can lead to a variety of neurological problems.
