What is found in the dorsal root of spinal nerves?

The dorsal root and ventral root of the spinal nerves can be distinguished in the spinal cord. 

The sensory nerve fibres make up the dorsal root and have their cell bodies in the dorsal root ganglion. 

The motor neurons make up the ventral root. 

The intervertebral foramen is where sensory and motor neurons enter and exit the spinal cord, respectively.
