Help With Homework Question Please!?
Which is the correct choices
1. Electrical currents involved in the production of action potentials are produced by:
a) movement by anions across the cell membrane
b) movement by cations across the cell membrane
c) a & b
d) none of the above
2. Myelination increases the speed of axonal conduction because
a) action potential travel faster in regions covered with myelin
b) myelination makes saltatory conduction possible
3. Regarding postsynaptic potentials
a) they are always the same size
b) their size depends on the amount of neurotransmitter released into the synaptic cleft by the presynaptic neuron
c) always depolarizing
d) they propagate by saltatory conduction
