Webb18 mars 2024 · Smooth muscle differs from striated muscle in many ways. T-tubules, myofibrils and sarcomeres are all absent, in contrast to striated muscle. Actin and myosin contractile proteins are present, as are thick and thin filaments. However, these are arranged differently. WebbWhen signaled by a motor neuron, a skeletal muscle fiber contracts as the thin filaments are pulled and then slide past the thick filaments within the fiber’s sarcomeres. This …
