sometimes the terms neuron and nerve are mistakenly used interchangeably. explain the difference between the two structures.

Mention to the function of myelin sheath.

In neurology, Will abolishing extracellular calcium concentration prevent electrical neuro transmission from occurring? Please explain in  a few sentences.

List the three parts of a typical neuron and state the function of each part.

Summarize the functions of each of the types of neuroglia (the exam will not ask about satellite cells) and describe how the myelin sheath is formed around a peripheral nervous system neuron. Explain why nerve impulse propagation is compromised in patients with multiple sclerosis. Distinguish between the composition of white matter and gray matter.

Transcranial Magnetic Stimulation causes an involuntary motor output in response to a magnetic stimulation over the skull. Why do we see this output?  Include the following concepts in your response: •neuroanatomy •central versus peripheral nervous system •neuron structure and direction of information flow •hyper versus depolarization •specific ions •membrane potential •diffusion and electrostatic pressure

Describe how an action potential in the presynaptic neuron is generated in the postsynaptic neuron. Label the presynaptic neuron, postsynaptic neuron and synapse. Explain what is happening in figure on the left. Use key terms in order AND label on diagram: presynaptic axon terminal, action potential, calcium, vesicle, neurotransmitters, synapse Explain what is happening in the figure on the right. Use key terms in order AND label on diagram: neurotransmitter, postsynaptic receptor, sodium ions, excitatory postsynaptic potential (EPSP), depolarization, action potential, postsynaptic neuron

In one to two sentences name and describe the three parts of the neuron.

a. Explain how a graded membrane potential is created when a neurotransmitter is bound by a postsynaptic cell. b. Describe the major events of an action potential using the graph of membrane potential.

Myelin sheaths function to electrically insulate neurons. Compare and contrast the myelination in the CNS and PNS (hint: include the cell types and their specific properties).
