ANATOMY OF THE SPINAL CORD. 2/1 While the cervical region, therefore, contains fibres for thearms, the trunk, and the legs, in the lumbar region it con-tains those for the legs only. The fibres for the legs evi-dently occupy the posterior portion of the tract in the cer-vical region, and as a result the pyramidal tract narrowsdown in this direction as it reaches lower and lower inthe
