Action Potentials
Graded Potentials
Match the characteristic/descriptor in the left-hand column with the correct type of change in membrane potential listed in the right-hand column.
Question 16 options:
12
propagate along the length of the axon with no decrease in magnitude as they move away from their site of origin
12
are decremental changes in membrane potential - meaning they are the type that decrease in magnitude as they spread further from their sites of origin
12
cause an actual reversal of membrane potential during which the inside of the cell membrane temporarily becomes positive with respect to the outside of the cell membrane
12
are non decremental changes in membrane potential - meaning they propagate along the plasma membrane with no observable decrease in intensity as they move further and further from their sites of origin
12
occur in the 'receptive' regions of the neuron - including the cell body and dendrites - in response to opening of ligand-gated ion channels
12
begin at the axon hillock and propagate to the axon terminal
12
occur along the length of the axon in response to opening of voltage-gated sodium and potassium ion channels
12
weaken as they spread further and further along the plasma membrane and away from their site of origin
12
required no 'threshold' change in membrane voltage to occur.
12
occur in 'all or none' fashion
