The two roots jointo form a nerve before they pass out of the neural canal; just before 44 MUSCULAR CONTROL they join the posterior root has an enlargement upon it that iscalled a spinal ganglion. The four roots and the two fissures divide the outer or whitepart of the cord into six columns that extend its whole length: two anterior, two lateral, and twoposterior. Micro
