Spinal Nerve Root

The spinal nerve root is a very important anatomical structure in the human body. It is formed from the roots of each spinal nerve - each of them is associated with a specific part of the body. The ossicles of the posterior branches of the roots partially form the fascial sheath covering the posterior surface of the kidney, and also pass to the iliosacral fascia, where they join the perineural sheath of the filum terminale.
