In what direction does a nerve impulse travel through a neuron?
from the axon terminal and up the axon towards the dendrites
from the dendrites and down the axon towards the axon terminal
from the nucleus in the cell body out towards the ends of the dendrites

A nerve impulse is also known as ____________________ in a neuron.
passive potential
action potential
basic potential
negative potential
During which phase off action potential transmission does the neural membrane experience a large influx of sodium ions? Does this make the inside of the neuron more positive or negative?
Repolarization; negative
Hyperpolarization; positive
Depolarization; positive
Resting Membrane Potential; negative
During which phase off action potential transmission does the neural membrane experience a large outflow of potassium ions? Does this make the inside of the neuron more positive or negative?
Repolarization; negaitve
Depolarization; positive
Hyperpolarization; negative
Resting Membrane Potential; positive
During Hyperpolarization, the sodium channel closes, but the potassium channel remains opened briefly, which continues to decrease the membrane potential, making it ___________________ resting membrane potential.
