5. Describe the function of CSF.

6. Name the 4 main parts of the brain.

7. Name the 3 parts of the brain stem and describe their locations.

8. Which cranial nerves originate from the brain stem?

9. Explain why the right cerebrum controls left muscular movements of the body.

10. Describe the functions of the medulla oblongata.

11. Describe the function of the reticular formations (Reticular Activating System).

28. Name the cranial nerves, their function, whether they are mixed, and through which foramen/foramina each travels.

29. Describe the sensory pathways to the brain.

30. Describe the motor pathways away from the brain.

31. Define UMN (upper motor neuron) and LMN (lower motor neuron).

32. Describe some possible mechanisms of memory.
