(neuroanatomy) The ganglia situated on the dorsal root of spinal nerves. These ganglia contain the cell bodies of sensory neurons; hence, they are chiefly involved in the transmission of sensory information.
In vertebrates, there are two major groups of ganglia. The ganglia located near and associated with the spinal nerves are the dorsal root ganglia. The cell bodies of sensory neurons are found in these ganglia. The other group is called autonomic ganglia.
