In spinal nerves, the dorsal nerve root connects to the spinal cord by 8 branches.
- In order to modulate motor and sensory information from the body's periphery, spinal nerves, which are mixed nerves, directly communicate with the spinal cord. Each nerve is made up of fila radiculara, or nerve fibers, which originate from the anterior (ventral) and posterior (dorsal) roots of the spinal cord. Through interneurons, the roots are linked.
- In a gross way, the root fibers combine to form a spinal nerve within the intervertebral foramina. Afferent sensory axons in the dorsal root relay information from somatic and visceral peripheral receptors to the central nervous system. The body's dermatomes, which are organized regions, can be used to map areas of cutaneous sensory innervation by particular spinal nerves.
