Spikes of electrical activity recorded during an EMG that reflect the number of motor units activated when the patient voluntarily contracts a muscle
muscle twitch
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
initial segment
no but generator potential can be summated
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
action potentials are non-decremental and do not get weaker with distance.

A neuron will generate action potential when it is stimulated by a neurotransmitter.
