Using the South University Online Library or the Internet, research about brainstem, diencephalon, cerebellum, and cerebrum. Based on your research and understanding, respond to the following:

1. Analyze the four sections of the brain stem, their individual functions, and their component role in brain physiology.
2. Categorize the brainstem, diencephalon, cerebellum, and cerebrum in terms of anatomy and functions.
3. Evaluate the functions of the ventricles of the brain and the choroid plexus, including their role in the formation and maintenance of CSF.
4. Distinguish the cranial nerves and categorize if the nerve is sensory, motor, or mixed and its major function(s).
