What type of information is traveling through the dorsal root of the spinal cord?

What types of information pass through spinal cord?

Anterior rootlets carry motor information out of the spinal cord (i.e. they contain efferent fibers) while the posterior rootlets carry sensory information into the spinal cord (i.e. they contain afferent fibers).

How does sensory information enter the spinal cord?

In transverse sections, the gray matter is conventionally divided into dorsal (posterior) lateral and ventral (anterior) “horns.” The neurons of the dorsal horns receive sensory information that enters the spinal cord via the dorsal roots of the spinal nerves.

What happens if your spinal cord hurts?

What part of the spinal cord receives sensory input?

The dorsal horn is found at all spinal cord levels and is comprised of sensory nuclei that receive and process incoming somatosensory information. From there, ascending projections emerge to transmit the sensory information to the midbrain and diencephalon.
