Document Summary
Made up of nervous tissue - (neurons and glial cells (supporting structures)) Part of the cns, connects brain to pns (helps them communicate) Extends from foramen magnum (hole at base of skull) to occipital bone to lumbar vertebrae #2. Boney structures (vertebrae) create the vertebral column by stacking up. On this side each individual vertebrae has opening called vertebral foramen, these holes create the vertebral canal. The vertebral column is curved (also why the spinal cord is curved), so it creates regions (superior to inferior): This is also where the most inferior rib is. There are spaces in between the vertebrae of the vertebral column called intervertebral foramina which is where the spinal nerves exit out to the pns. The vertebral column grows until you"re an adult, whereas the spinal cord stops growing at 3-4 years of age, therefore the vertebral column is longer than the spinal cord.
