Slide 82: Multipolar neurons

Silver

This is a cross section through the spinal cord and spinal ganglion. The spinal cord is used as an example of multipolar neuron cell bodies.

Also visible are the nerve ends (synapses) of the central nervous system, which are situated on the neuron cell bodies of the large anterior horn of the spinal cord.

Identify microscopically:

  1. Cell bodies

  2. Nuclei

  3. Neurofibrils

  4. Meshwork

  5. Nuclei of neuroglia

  6. Neuron bodies

  7. End plates

Draw and annotate:

A multipolar neuron.

A neuron cell body with end plates included.

 

Reflection:
  1. Is the neuron nuclei visible?
  2. How do the neurofibrils appear and what are they in reality?
  3. What is the meshwork surrounding the cell bodies in reality?
  4. How are the end plates presented under the light microscope?
