Spinal nerves are the main nerves of the body. A overall of 31 pairs of spinal nerves manage motor, sensory, and different functions. These nerves are placed on the cervical, thoracic, lumbar, sacral, and coccygeal levels.
Each spinal nerve is shaped through the aggregate of nerve fibers from the dorsal and ventral roots of the spinal. The dorsal roots convey afferent sensory axons, even as the ventral roots convey efferent motor axons. The spinal nerve emerges from the spinal column via an opening among adjoining vertebrae.
The vertebral foramen affords for passage of the spinal. Each spinal nerve exits via an intervertebral foramen, placed among adjoining vertebrae. Intervertebral discs unite the bodies of adjoining vertebrae.
