This 25 minute video is a step-by-step building of what spinal nerves consist of and now they are organized going in and out of the spinal cord. This building also guides students to visualize how the vertebral disc plays a major role in providing space for the spinal nerve.
This lesson blends Star's Notes Module IVB and Hands-On Body Systems: Movement & Communication pages 37-57. I added a 'new trick' to this building activity. :)
