WebA motor unit is made up of a motor neuron and all of the skeletal muscle fibers innervated by the neuron's axon terminals, including the neuromuscular junctions between the neuron and the fibres. [1] Groups of motor units often work together as a motor pool to coordinate the contractions of a single muscle. The concept was proposed by Charles ... WebQ1. Motor unit is one motor neuron and all the muscle fibers it innervates. each motor neuron innervates several of the same type of muscle fibers, but each muscle fiber is innervated by only one motor neuron. recruiting more motor units will produce a higher mean emg amplitude and stronger contraction. the motor neuron is associated with voluntary … WebThe myosin head is now in position for further movement. When the myosin head is cocked, myosin is in a high-energy configuration. This energy is expended as the myosin head moves through the power stroke, and at the end of the power stroke, the myosin head is in a low-energy position. hampton elementary rochester hills
