What Is the Dorsal Column?

The back pillar is also called the "back pillar". Generally refers to the posterior horn of the gray matter of the spinal cord. It can also refer to the posterior cord of the white matter of the spinal cord. In the posterior horn, there are nucleuses such as the posterior horn marginal nucleus, colloid, and posterior horn intrinsic nucleus. Layered according to Rexder, the posterior corner includes layers I to VI: layer I is equivalent to the posterior corner edge area, and the posterior corner edge nucleus is inside; layer II is equivalent to the gelatinous layer; Intrinsic nucleus; layers V and VI correspond to the posterior corner base. The posterior cable is a fiber bundle that rises after the medial group of the posterior roots enters the spinal cord. ^[1]
