WebSensory information is carried by sensory neurons in dorsal roots, which enter the cord in small bundles called dorsal rootlets. The cell bodies for these sensory neurons are clustered together in a structure called the dorsal root ganglion, which is … 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.

All spinal nerves—except the first pair—emerge from the spinal column through an opening between vertebrae, called an … WebAll of the spinal nerves are combined sensory and motor axons that separate into two nerve roots. The sensory axons enter the spinal cord as the dorsal nerve root. The motor fibers, both somatic and autonomic, emerge as the ventral nerve root. The dorsal root ganglion for each nerve is an enlargement of the spinal nerve. 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. coastal fog paint benjamin moore
