1. Action Potentials
2. Graded Potentials
Match the characteristic/descriptor in the left-hand column withthe correct type of change in membrane potential listed in theright-hand column.
Question 16 options:
12
propagate along the length of the axon with no decrease inmagnitude as they move away from their site of origin
12
are decremental changes in membrane potential - meaning they arethe type that decrease in magnitude as they spread further fromtheir sites of origin
12
cause an actual reversal of membrane potential during which theinside of the cell membrane temporarily becomes positive withrespect to the outside of the cell membrane
12
are non decremental changes in membrane potential - meaning theypropagate along the plasma membrane with no observable decrease inintensity as they move further and further from their sites oforigin
12
occur in the 'receptive' regions of the neuron - including thecell body and dendrites - in response to opening of ligand-gatedion 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 ofvoltage-gated sodium and potassium ion channels
12
weaken as they spread further and further along the plasmamembrane and away from their site of origin
12
required no 'threshold' change in membrane voltage to occur.
12
occur in 'all or none' fashion
