QuestionAnswer
which embryonic plate of the spinal cord gives rise to the dorsal horn of the spinal cord?

another anatomical term that means basal
the ____ zone forms the white matter of the spinal cord
what gives rise to the midbrain?
dilation of the ventricles due to an excess of CSF that may result from either a blockage of CSF circulation or, rarely, an overproduction of CSF (e.g., due to a choroid plexus pap
