Transcription: The spinal cord, located in the vertebral canal, is a strand which has two spindle-shaped swellings containing a particularly high number of nerve cells near the cervical and lumbar vertebra and which ends as a thin strand. Thirty-one pairs of spinal nerves lead out of holes within the spine, the so-called invertible foramina, supplying the individual parts of the body. The spinal nerves each consist of a back root for sensory impulse and a front route for motoric impulses. The two meeting just before they exit through their invertebral foramen.
