Each spinal nerve is attached to the spinal cord by two roots: a dorsal (or posterior) sensory root and a ventral (or anterior) motor root. The spinal nerves exit the spinal cord and pass through_the intervertebral foramen.

What is the function of the spinal nerves? Spinal nerves. Spinal nerves are an integral part of the peripheral nervous system (PNS). They are the structures through which the central nervous system (CNS) receives sensory information from the periphery, and through which the activity of the trunk and thelimbs is regulated.

What does the ventral root of the spinal cord do? Ventral Root. The Ventral Root of the spinal nerve contains outgoing, efferent (meaning to "bear away from") fibers that carry information destined to control motor or glandular function. The ventral root joins with the dorsal root outside the-vertebral column to form a spinal nerve.

What is a spinal nerve root? Spinal nerve roots are the fiber bundles that come off the spinal cord. For each spinal segment, (which is the area of the spinal cord that corresponds to the level of the vertebra through which the nerves will exit on their way out to all parts of the body) there are four nerve roots—two in front and two in back.
