Slide 59: Peripheral nerve: myelinated fibers

Osmium

This is a cross-section through a peripheral nerve that has been stained for myelin.

Identify microscopically:

  1. Myelin sheath

  2. Axon

Draw and annotate:

A number of myelin sheaths in detail.

 

Reflection:
  1. Are all the axons and myelin sheaths sectioned the same?
  2. Why can't the structure of the axons be seen?
