Temporal summation is used in the body to
A) decrease muscle contraction in muscle fibers, to prevent damage to the cells.
B) increase the amount of force generated by skeletal muscle fibers.
C) maintain constant tension in a muscle fiber every time it contracts.
D) activate nearby skeletal muscle fibers, when a muscle fiber is under constant stimulation.
E) accomplish all of these functions.
Temporal Summation
A mechanism of signal transmission in neurons where multiple signals are combined over a period of time to generate a larger response.
Muscle Fibers
Muscle fibers are the individual contractile units of muscle tissue, made up of myofibrils and encapsulated in a sarcolemma, that facilitate body movements through contraction and relaxation.

Final Answer :
B
Explanation :
Temporal summation is used to increase the amount of force generated by skeletal muscle fibers by rapidly stimulating the muscle fibers, leading to greater tension and force production. It does not decrease contraction, maintain constant tension, or activate nearby fibers.
