The dorsal root is sensory, and the ventral root is motor; the dorsal root may be absent in the first cervical nerve. The dorsal roots are distinguished by oval swellings known as spinal ganglia. They are made up of nerve cells, which give rise to sensory nerve fibers. The dorsal roots of the spinal nerve are in charge of sensory perception, whereas the ventral roots are in charge of motor control and functioning.
