10.3 Muscle Fiber Excitation, Contraction, and Relaxation
WebDuring contraction the energy of muscle tissue increases due to energy from the hydrolysis of ATP. This energy is distributed across the tissue as strain-energy potentials in the contractile elements, strain-energy … WebThus, the excitation-contraction coupling process begins with signaling from the nervous system at the neuromuscular junction ( Figure 10.3.1) and ends with calcium release for muscle contraction. Figure 10.3.1 – Motor End-Plate and Innervation: At the NMJ, the axon terminal releases acetylcholine (ACh). The motor end-plate is the location of ... crystal flies location
