The duration of a single neuronal action potential (excluding the afterhyperpolarisation, which can be quite long-lasting) is approximately how many milliseconds?

The entire action potential (depolarization and repolarization) occurs in a matter ofMultiple Choicemilliseconds.seconds.minutes.hours.days.

For a typical neuron, what limits the maximal frequency attainable of action potentials moving down an axon?

For a typical neuron, what limits the maximal frequency attainable of action potentials moving down an axon?Multiple ChoiceThe refractory periodThe types of ions contributing to the action potentialThe strength of each action potentialThe strengths of the graded potentials on the neuron cell body and/or dendrites

Which of the following helps create the refractory period for action potentials frequency in muscle and nerve cells?Group of answer choicesclosed activation gate on voltage gated sodium channelslag for restoration of resting membrane potential by sodium-potassium pumpinability to reach threshold potential for the cellclosed inactivation gate on voltage gated sodium channelsclosed gates on voltage gated potassium channels

In temporal summation, a single presynaptic neuron stimulates the creation of action potentials in a postsynaptic neuron when it
