Compare and contrast wave summation with recruitment. How are they similar? How was eas achieved in the simulation?

Muscles are stimulated to contract by electrical signals, usually from the brain. These waves of electricity can be piled on top of each other, causing increased strength and duration of muscle contraction. Motor recruitment involves sending signals to multiple parts of the muscle at once, resulting in one quick, strong contraction. Summation is similar in that it increases contractile force.

Both cause an increase in force generated. Summation is achieved by increasing frequency of stimulation. Recruitment is achieved by increasing force of stimulation.
