CJ and Tye are studying a model of cross-section of the spinal cord in lab.  CJ is confused about which side of the model is anterior vs. which is posterior.  Tye says that it is easy to tell which side is which.  What does the Tye use to distinguish between the sides of the model? A) The posterior (dorsal) side will have a ganglion on the nerve root. B) The anterior (ventral) median fissure is deeper and wider than the posterior median sulcus. C) The central canal is closer to the posterior side.
