WebMyosin is the main regulatory protein in skeletal muscle. 3. Skeletal muscle usually exhibits spontaneous activity, while smooth muscle cannot contract spontaneously. 4. Only skeletal muscle requires increased calcium ion concentration in the cytosol for contraction. 5. Only skeletal muscle has both actin and myosin. WebExcitation signalling of action potentials from the motor neuron are coupled with calcium release. Thus, the excitation-contraction coupling process begins with signaling from the nervous system at the neuromuscular …
