Answer:
The sensory impulses generated in the periphery (pain, touch, temperature changes) activate the peripheral processes of the spinal ganglion neurons. These impulses then travel to the spinal cord either directly (bypassing the cell bodies) or through the neuronal cell body in the dorsal root ganglion.
Step-by-step explanation:
The dorsal root transmits sensory information, forming the afferent sensory root of a spinal nerve. The dorsal root of the spinal nerve mediates the movement of motor impulses to go out of the spinal cord
Dorsal Roots: convey mainly “afferent” sensory information into the dorsal spinal cord. (Blumenfeld, 22) Also referred to as 'dorsal nerve roots. ' Ventral Roots: carry mainly “efferent” “motor” and “signals” from the ventral spinal cord to the periphery.
