Increasing the frequency of action potentials in a somatic motor neuron will induce increased force of muscle contraction.

Question

Quizplus · Accepted Answer

Increasing the frequency of action potentials in a somatic motor neuron will result in an increase in muscle contraction force, a phenomenon known as temporal summation. This is due to the fact that more action potentials lead to more Ca2+ release from the sarcoplasmic reticulum of the muscle fiber, which increases the number of cross-bridges that can form between actin and myosin filaments, resulting in greater force production.
