11) Explain saltatory conduction using the terms action potential (ne.pdf

11) Explain saltatory conduction using the terms action potential (nerve impulse), Schwann cell,
oligodendrocyte, myelin, myelin sheath, energy conservation, voltage-gated channels, channel
distribution and nodes of Ranvier. In which part of a neuron does saltatory conduction occur? 12)
Describe reflexes. How do reflexes work? What are the 5 steps of a typical reflex arc? (A
monosynaptic reflex arc.) 13) Describe depolarization, hyperpolarization and threshold potential.
What is the relationship between the arrival of an action potential (nerve impulse) at the axon
terminus and exocytosis of neurotransmitters? 14) What is an IPSP? What is an EPSP? Which
hyperpolarizes the membrane? Which depolarizes the membrane? Which takes the neuro closer
to an action potential (nerve impulse)? Which takes it farther from an action potential (nerve
impulse)? Where do they occur and why are they important? 15) What is summation? What is
the difference between temporal summation and spatial summation? What happens when two or
more graded potentials arrive at the axon hillock?.
