WEEKLY OVERVIEW

---

• In lectures on Tuesday and Thursday, we will begin to put together a central nervous system from the basic parts that you now understand.

• We start with an overview of the brainstem and cranial nerves, building on principles you encountered in the spinal cord lecture last week.

• Pay attention to terminology, particularly the names of external and internal landmarks.

• Begin to recognize on cross sections, groups of neuron cell bodies (nuclei=gray matter) and their axons (tracts=white matter).

• If you have nothing else to do, quiz each other on the cranial nerves: names, numbers, brainstem attachment sites, and eventually, major functions represented clinically.

• Continue having a good time with all this!
