The wedge-shaped fiber bundle of white matter in the dorsomedial side of the spinal cord that is made up of the fasciculus gracilis and fasciculus cuneatus; it is part of the ascending posterior column-medial lemniscus pathway that is important for well-localized fine touch and conscious proprioception.

The dorsolateral ridge of gray matter in each lateral half of the spinal cord. [TFD][VHOG]
The dorsal column is a part of the spinal cord which is responsible for transporting sensory input from the body to the cerebral cortex. This part of the spinal cord is key in perceiving fine touch, such as that used to distinguish textures, along with vibration. The dorsal column also contributes to the body's system of proprioception, used to orient the body in space and to coordinate muscle movements, given information about the body's position
