Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.

Annotation

/surg: consider RHIZOTOMY; DORSAL ROOT GANGLIA see GANGLIA, SPINAL is also available; inflammation = RADICULITIS (single root) or POLYRADICULITIS (several roots) or POLYRADICULONEURITIS (nerve roots & peripheral nerves); do not use vertebra headings to locate area of spinal nerves; nerve root compression: coordinate IM with NERVE COMPRESSION SYNDROMES (IM), not SPINAL CORD COMPRESSION
