Local current flow
A)occurs only on dendrites of neurons
B)causes impulses to move from the axon hillock toward the neuron's cell body
C)involves current flowing between active and adjacent inactive areas, thereby bringing the inactive areas to threshold
D)occurs only on axons of neurons
E)does not occur on all excitable membranes

Question

Quizplus · Accepted Answer

Local current flow involves the flow of ions between active and adjacent inactive areas, causing the inactive areas to reach the threshold for depolarization and the initiation of an action potential. This process can occur on both dendrites and axons of neurons and is not limited to excitable membranes. However, option A and D can be eliminated as they are not accurate statements. Option B is incorrect as impulses always move away from the axon hillock towards the axon terminal.
