Identify microscopically:

1. Epi-, peri- and endoneurium

2. Axon

3. Neurilemma

4. Schwann cell nuclei

Draw and annotate:

A line diagram of the nerve in which the connective tissue components and nerve bundles are indicated. Draw a few cross sectional axons with their sheaths.

1. How do the axons appear?
2. How do the myelin sheaths appear?
3. How does one distinguish between Schwann cell and fibroblast nuclei?
4. How do unmyelinated fibers appear?
