Each nerve forms from nerve fibers, known as fila radicularia, extending from the posterior (dorsal) and anterior (ventral) roots of the spinal cord. Web there are 31 pairs of spinal nerves: Numbers indicate the types of nerve fibers: It provides a visual representation of the anatomy and physiology of the nervous system, which helps to explain the function of the spinal nerves.
