Thoracic region of spine

Lab quiz 8 will be on the spine, the PNS and the ANS. There will be some overlap on the models. Below is a longitudinal section of the spinal cord and the PNS. This page will focus on the thoracic region of the spine. The black box in the lower left is a zoomed in (and more clear) image of the smaller black box. Be sure to see the zoomed in cervical, and lumbar as well as thewhole spine regions. Also be sure to see the brachial and Lumbo-sacral plexus pages as well.
