WebThese subdivisions have different amounts of myelination and axon thickness and therefore transmit signals at different speeds. Larger diameter axons and more myelin insulation lead to faster signal propagation. Group A nerves are found in both motor and sensory pathways. WebThe dorsal roots contain only the axons of sensory neurons carrying information to the CNS from the periphery. The dorsal root ganglion for each nerve is seen as an enlargement of the dorsal root near the spinal nerve, and it it contains the cell bodies for pseudounipolar sensory neurons.
