spinal nerve

Any of the 31 sets of nerves originating in the spinal cord and emerging from the spinal canal through intervertebral foramina. Each spinal nerve is the concatenation of two sets of axons that emerge separately from the spinal cord: sensory axons (the dorsal root) and motor axons (the ventral root). See: illustration

spinal nerve

any of numerous nerves which leave the SPINAL CORD, one pair in each segment, each being connected with the cord by a dorsal and a ventral root. They are ‘mixed nerves’ (containing both sensory and motor fibres) and carry groups of AXONS to receptors and effectors in different parts of the body see REFLEX ARC.
