Hi, I'm taking the exam Saturday. I"m reviewing my practice exams and what not. In regard to anatomy I know a lot of it. Do we need to know the anatomy of the brain? I know the layers (dura, arachnoid and pia) and the parts but do we need to know the ventricles? Do we need to know what part of the brain is responsible for what activities (motor, speech hearing etc). How much in depth with the brain go on the CPC exam?
