dorsal root ganglion

Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain. (MSH) * ganglion found on the posterior root of each spinal nerve, composed of the unipolar nerve cell bodies of the sensory neurons of the nerve. (CSP).

What the dorsal root ganglion is

Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain. (MSH) * ganglion found on the posterior root of each spinal nerve, composed of the unipolar nerve cell bodies of the sensory neurons of the nerve. (CSP). The atlas records it as a nerve at the organ scale in the human body.

Where the dorsal root ganglion is

It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.

What the dorsal root ganglion connects to

The atlas records 5 typed relationships for it, across 2 kinds of connection. a kind of sensory ganglion.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the dorsal root ganglion. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the dorsal root ganglion?

It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.

What does the dorsal root ganglion connect to?

A kind of: sensory ganglion.

Is the dorsal root ganglion the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
