Neuron Signaling and Muscle Contraction
1) “Dissect” the various parts of an action potential by
describing the status (active or nonactive) of the voltage-gated
sodium channel, voltage-gated potassium channel, sodium/potassium
pump, and overall voltage and/ or voltage range (in millivolts, or
mV) for each of the following.
A) Resting membrane (prior to the initiation of an action
potential)
B) just before threshold to just after threshold
(Depolarization)
C) Rising phase of the action potential
D) Falling phase of the action...
