Abstract: The spinal cord begins as the cervical cord immediately below the medulla and extends through the spinal canal, where it becomes the thoracic, lumbar, sacral, and coccygeal parts of the cord. In most persons, the spinal cord proper ends at the lower portion of the first lumbar vertebral body, where it forms the conus medullaris and, finally, the filum terminale. A cervical enlargement contains the innervation pathways of the upper limbs; a lumbar enlargement contains the pathways of the lower limbs. This chapter reviews ascending and descending pathways in the spinal cord.
