We have 31 pairs of spinal nerves and they are named after the section of the spine they come out of. 8 pairs of cervical nerves (C1-C8) 12 pairs of thoracic nerves (T1 â T12) 5 pairs of lumbar nerves (L1-L5) 5 pairs of sacral nerves (S1-S5)
There are 31 pair of spinal nerves & each has a dorsal root and a ventral root. The dorsal root is sensory (all neurons conduct impulses into the spinal cord) while the ventral root is motor (all neurons conduct impulses out of the spinal cord). The dorsal root has a ganglion that contains the cell bodies of the sensory neurons that pass through the dorsal root.
