Lab 10 Exercise \(\PageIndex{1}\)

Identify the pats of a "neuron"

Lab 10 Exercise \(\PageIndex{2}\)

Label the following:

1	Axon
2	Synaptic cleft
3	Receptor,
4	Neurotransmitter
5	Synaptic terminal
6	Vesicles
7	Voltage-gated ion channels.

Lab 10 Exercise \(\PageIndex{3}\)

Match these items or actions to their locations on a neuron: graded potentials, action

1	graded potentials	7	EPSPs
2	action action	8	IPSPs
3	neurotransmitter-filled vesicles	9	pre-synaptic membrane
4	neurotransmitter receptors	10	post-synaptic membrane
5	voltage-gated sodium channels	11	Genes (that encode receptor proteins)
6	ligand-gated ion channels

Lab 10 Exercise \(\PageIndex{4}\)

Label the following glia & related items:

1	Astrocyte	6	Cerebrospinal fluid (CSF)
2	Perivascular feet	7	Extracellular fluid (ECF)
3	Oligodendrocyte	8	Neuron
4	Microglia	9	Capillary
5	Ependymal cell

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.
