Questions and Answers
1. Phase 1; voltage-gated sodium channels are : closed
2. phase 1: voltage-gated potassium channels are : clsoed
3. phase 2: voltage- gated sodium channels are : open
4. phase 2 : voltage-gated potassium channels are : closed
5. phase 3: volatage-gated sodium channels are : inactivated
6. phase 3: voltage gated potassium channels arte : open
7. phse 4; volatge gated sodium channels are : closed
8. phase 4: volatge-gated potassium channles are : opne
9. voltage-gated sodium channels are likley open and that voltage0gated
pota- sisum channles are likely closed or just opening. the membrane is far
more permeable to sdoim than to potassium. sodium ions wil enter the
neruon through voltrage-gated soodium channels and potassoum ions will
exit the neuron throih voltage-gatd potassoum channles if open: during an
action poten- tial, the membrane potential can become a positive value.
expian why the membrane potetnial become postiive. indicate the state
of volatage-gated sodium and potassi- um channles when the
membrane has a postivie volage, the relative permeabiity go the
membrane ot sodium and potassium ion, the net direction of sodium in
flow and net direction of potassium ion flow.
10. action potentials propagte fasrte
in axons. in additon, they propagte
faster along axons: wider; myelinated
11.synapese A,B, adn C are all exitatory synapes such that the release of
glutamte at eahc synapse results in a similar degree of postive current to
enter the cell. the realse fo neruotransmitter at is more likley to elicit an
aciton potetnial in the postsynpatic neuron. This because the synpase is
close to a region where there is a higher denstiy of .: C; voltage-gated
sodium channels
12.synapes A and B are both consdiered axodendritic synapses. using
hte same naiming convention, synapse C is called a: axosomatic



13.at synapse D, the pesynatpic neuron relases GABA, which is a (n) neu-
rotrnsmitter tha tbinds to GABAergic recepotrs on the postsynpatic neuron.
given a reastong membrane potential of -60mV, the opening of GABAergic
receptors will ions to the postynaptic neuron: amino acid; chloride;
enter
