Describe the cross-sectional anatomy of the spinal cord
What will be an ideal response
The spinal cord is slightly flattened in its anterior-posterior dimension. It has two grooves: anterior median fissure and shallower posterior median sulcus. The central canal contains CSF. The gray commissure surrounds the central canal, and forms the cross bar of the H. It contains the axons that connect the two sides of the gray horns (anterior, posterior, lateral). White matter surrounds the gray and is subdivided into columns (anterior, posterior, lateral). The anterior white commissure is anterior to the gray commissure.
