Nerve Notes from 6.5 (start on Monday 3/14 and continue after test 3/16).

1. What 2 systems of the body are used for internal communication?
2. What does a neuron do and about how many does the human body have?
3. Draw and annotate a diagram of a neuron with dendrites, cell body, axon, and motor end plates.
4. Describe how a cell gets a myelin sheath, and explain what it does to the rate of conduction (include nodes of Ranvier).
5. Explain how neurons generate a resting potential and state what the typical resting potential is in millivolts (mV).
6. Outline the process by which a neuron becomes depolarized (give a value too) and then repolarized.
7. How is an action potential propagated along the axon of a neuron?
8. What is a synapse?
9. List the steps involved in a synaptic transmission.
10. Outline the secretion and reabsorption of acetylcholine by neurons at synapses.
11. What do neonicotinoids do and why have they been in the news around here when it comes to bees?
