Diagram of a transverse section of the spinal cord and vertebral column. The orientation is so that a cross section of a vertebral body is at the top and a cross section of a spinous process is at the bottom of the image. There are two branches coming out of the spinal cord on each sides. The bottom two branches have a thickening in them (one is labeled B). One of the top two branches is labeled A. The top and bottom branches on each side unite for a while and then the resulting fiber splits again into a top and a bottom branch as well as a separate smaller branch coming off of the top branch. One of the top branches is labeled D and one of the bottom ones is labeled C.

The anterior ramus is labeled _____.

A

B

C
