Document Summary

Spinal cord is a long structure comprised of nervous tissue: neurons and associated glial cells. Part of the cns connects brain to pns. Bony structures vertebrae to form vertebral column. Each individual vertebrae has an opening called the vertebral foramen: hole within the region where these spinal processes are. When you stack the vertebrae together hole formed called the canal. Each curve is divided into a region vertebrae named accordingly: cervical region, thoracic region. Lumbar region o: sacral and coccygeal regions. Intervertebral foramina is the opening or space between the vertebrae: where spinal nerve exits spinal cord. Spinal cord stops growing in length around 4-5 years but vertebral column does not end for a while. Communication link between the brain and the pns (below the head: spinal cord is the super highway where all the small nerves converge to get to the brain.
