Web17 de jan. de 2024 · A motor unit consists of the motor neuron and the grouping of muscle fibers innervated by the neuron. The number of muscle fibers within a motor unit varies, and is a function of the muscle’s ability for accurate and refined motion. Precision is inversely proportional to the size of the motor unit. The central nervous system is responsible for the orderly recruitment of motor neurons, beginning with the smallest motor units. Henneman's size principle indicates that motor units are recruited from smallest to largest based on the size of the load. For smaller loads requiring less force, slow twitch, low-force, fatigue-resistant muscle fibers are activated prior to the recruitment of the fast twitch, high-force, less fatigue-resistant muscle fibers. Larger motor units are typically compose…
