Which description best matches the ventral root ganglion?

The ventral root carries motor, efferent signals from the spinal cord to the periphery. The actual cell bodies of these motor neurons sit in the ventral (anterior) horn of the spinal cord, not in a ganglion along the root. A dorsal root, with its dorsal root ganglion, handles sensory afferent information. Since the ventral root is pure motor output, describing it as motor, efferent is the best match. Interneurons are located within the spinal cord gray matter, not in the roots, and mixed fibers would involve both sensory and motor, which isn’t the case for the ventral root.
