What can the nervous system do to increase muscle tension?

The nervous system can increase muscle tension through the recruitment of motor units and the frequency of action potentials sent to the muscles. When more motor neurons are activated, additional muscle fibers contract, leading to greater force production. Additionally, increasing the rate of stimulation (temporal summation) can enhance muscle tension by allowing muscle fibers to contract more forcefully before they have a chance to relax. This coordinated control allows for precise adjustments in muscle tension to meet various demands.
