Which statement about efferent impulses in the spinal cord is correct?

They travel along the spino-thalamic and spino-cerebellar tracts.
They pass along tracts that are located in the gray matter of the spinal cord.
The nerve cells that they travel through have their cell bodies located in the dorsal root ganglia.
The axons carrying these impulses pass through the ventral root of the spinal nerves.

D: Efferent impulses are motor impulses so leave the spinal cord via the ventral roots. “Spino-thalamic” means from spine to thalamus, i.e. ascending or sensory. Tracts are white matter not gray. Sensory neurons have their cell bodies in the dorsal root ganglia.
