Neuron Review

Label the parts of the neuron. (axon, axon hillock, cell body, dendrites, myelin sheath, nodes of Ranvier, and terminal branches.)

Synaptic Communication. Label the parts as best you can. Use the following terms: presynaptic neuron, postsynaptic neuron, vesicles, neurotransmitters, ligand-gated receptor channels, reuptake ports). Then draw in the movement of Na+ ions during this process.

Starting with resting potential as the first stage of neural transmission, correctly sequence the following stages.

The refractory period is when the neuron cannot fire. Draw a neuron, draw where the Na+ ions are during the refractory period, and write what needs to happen in order for the neuron to be repolarized.

Categorize the event of sub-structure into the correct part of the neuron.
