The dorsal root contains sensory neuron axons that carry information to the spinal cord, while the ventral root contains motor neuron axons that carry signals away from the spinal cord.

Front

What is the function of the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate.
