Rivian says it will save money and … 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… Web1 de jun. de 2024 · Based on this scheme, motor unit firing behavior follows a hierarchical organization that gives rise to two general properties: 1) earlier-recruited motor units maintain higher firing rates than later-recruited ones at any time and contraction force level, a property known as the “onion-skin” scheme of motor unit firing rates (Erim et al. … high altitude winds
