A dermatome is the region of skin innervated by a particular spinal nerve. The dermatomal pattern is best understood when depicted on a person in a quadrupedal posture.

The dorsal column system is the pathway in which the touch receptors that have sent their axons to the spinal cord, have entered the spinal cord through the dorsal horn and turn upward, traveling to the brain along the spinal cord's dorsal column of white matter.

The dorsal column nuclei are a cluster of nuclei found in the brainstem, specifically the medulla. These neurons are important because it is here where the axons of these neurons cross the midline to the opposite side.
