Question

resting potential is to action potential as ______ is to

• 2 points

temporal lobe; occipital lobe
polarization; depolarization
sensory neuron; motor neuron
dendrite; axon

increasing excitatory signals above the threshold for neural activation will * 2 points
not affect the intensity of an action potential. this indicates that a
neurons reaction is
primarily electrical rather than chemical
an all - or - nothing response
inhibited by the myelin sheath
dependent on neurotransmitter molecules

Explanation:

Resting potential is a polarized state of a neuron and action potential is a depolarized state. Also, a neuron's reaction to excitatory signals above - threshold is an all - or - nothing response, meaning once the threshold is reached, an action potential occurs at a fixed intensity.

Answer:

1. B. polarization; depolarization
2. B. an all - or - nothing response
