Web2. The relationship between axons of motor neurons and muscle fibers is. A) each axon innervates one, and only one, muscle fiber. B) the more muscle fibers a single axon innervates, the more precise the movements the muscle can make. C) the more axons there are innervating a single muscle fiber, the more precise the movements the muscle can … Web1 Jun 2002 · Collectively, the present data suggest that the increase in motoneuronal output induced by resistance training may comprise both supraspinal and spinal adaptation mechanisms (i.e., increased central motor drive, elevated motoneuron excitability, reduced presynaptic inhibition).

From: Encyclopedia of … WebA cross-bridge forms between actin and the myosin heads triggering contraction. As long as Ca ++ ions remain in the sarcoplasm to bind to troponin, and as long as ATP is available, the muscle fiber will continue to shorten.. Muscle contraction usually stops when signaling from the motor neuron ends, which repolarizes the sarcolemma and T-tubules, and closes the …

Web10 Jun 2024 · Muscle can experience post-activation potentiation (PAP), a temporary increase in force and rate of force development, when contractions are closely timed; therefore, cyclical behaviours are likely affected by PAP, as succeeding contraction cycles can lead to potentiation over several subsequent cycles.
