Definition
English
:
The 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 efferent, comprising the
axons
of spinal motor and autonomic preganglionic
neurons
. There are, however, some exceptions to this afferent/efferent rule.
