If pre synaptic neuron is firing quick enough, it can allow cell to reach

The amount of force is related to the amount of cross bridges made in the muscle.
Length of the muscle determines how much force you can produce.
Amount of overlap between thick and thin filaments.
Calcium is key for allowing the cross brid
