FIGURE 11-17 Haptic Neuron of the Posterior Root Ganglion The dendrite and axon of this neuron of the posterior root ganglion, which are contiguous, carry sensory information from the skin to the CNS. These large, myelinated ganglionic axons travel up the spinal cord to the brain in the posterior column, whereas the small axons synapse with neurons whose axons cross the spinal cord and ascend on the other side (shown in Figure 11-19).
