Action Potienal Conduction; Synaptic Transmisson Flashcards
Test:
How can action potentials conduct long distances without losing energy?
Because the depolarization due to the action potential causes local current flow in the axon.
Explain the conduction of action potential.
Why do we not have to worry about action potentials going back from where it came from?
Refractory period!
Explain the difference between graded potential conduction vs. action potential conduction.
What are the two factors that affect action potential conduction velocity?
Define the role myelin plays in neurons.
Define what the nodes of Ranvier is.
Define saltatory conduction.
When the action potentials jump from node to node as it conducts along the axon.
(Ex. In myelinated neurons)
Memorize:
Define what proprioceptors are and what neurons they interact with.
What are the two demyelinating disorders we need to know so far?
Multiple Sclerosis and Guillain-Barré syndrome.
Explain broadly how demyelination disorder is a problem.
What do we need to know about multiple sclerosis?
What do we need to know about Guillain-Barré syndrome?
PNS-Perphrial nervous system.
