Activation of motor units in a random order produces a roughly linear force increase with progressive recruitment, whereas recruitment of motor units in order of increasing force produces an approximately exponential force increase as the number of active motor units increases. The latter scheme allows fine control of weak movements and rapid. 3) the force of muscle contraction is controlled by multiple motor unit summation or recruitment. T 4) eccentric contractions are more forceful than concentric contractions.

Eccentric contractions are more forceful than concentric contractions. A motor neuron and all the muscle cells that it stimulates are referred to as a motor end plate. The phenomenon where one motor neuron innervates a group of muscle fibers in a muscle is called the motor unit. This unit controls skeletal muscles and is the major force behind movements. Groups of motor units often work together to coordinate the contractions of a single muscle; All of the motor units within a muscle are considered a motor pool. What is summation in muscle contraction? Summation occurs as successive stimuli are added together to produce a stronger muscle contraction. Tetanus is the fusion of contractions to.
