Lab 10 Exercise \(\PageIndex{5}\)
Label the histological sections
Lab 10 Exercise \(\PageIndex{6}\)
Obtain slides of each of the following tissues, observe them, draw and label the significant features. SLIDES: Spinal cord, cerebral cortex, cerebellum, dorsal root ganglion, peripheral nerve, neuromuscular junction:
1. Obtain a slide of nervous tissue from the slide box. Use any nervous tissue except peripheral nerve, there are no nerve cell bodies in a peripheral nerve section.
2. View the slide on the second-highest objective. Search carefully until you find a clear, representative neuron in your field of view.
3. In the circle below, draw the neuron you found. Only draw the single neuron. Do not draw any of the other material. Draw your structures proportionately to their size in your microscope’s field of view.
4. Label any neural parts you can clearly recognize.
