Crossection of spine at C6

Lab quiz 8 will be on the spine, the PNS and the ANS. There will be some overlap on the models. Below is a crossectional view of the spine at C6. Identify the structures below. Be sure to see the simple spine model and the reflex model.

 		Spine at C6 Model

Notes

  • Posterior = Dorsal
  • Anterior = Ventral
  • Ramus=singular. Rami=plural
  • Gray and white MaTTer
  • Dura, Arachnoid, and Pia MaTer.
  • Funiculus= area of white mater in the spine. Thus, technically the posterior white matter is also the posterior funiculus.
