These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins. The sarcolemma sends closed ended tubules into the sarcoplasm (T-tubules) that associate with terminal cisternae of sarcoplasmic reticulum (smooth ER, a site of Ca2+ storage) forming triads of A-I borders. composed of a big smooth muscle (detrusor muscle) which relaxes to store urine, and contracts to expel it from the body. ( which displaces tropomyosin, thus exposing myosin binding site in skeletal muscle contraction) myosin light chain kinase catalyzes transfer of phosphate from ATP to regulatory light chain of myosin, allowing the head to bind actin, and myosin binds actin - sliding filaments. The characteristics that allow these functions are contractility which is unique to muscle and excitability which is responding to sitmuli by generating an action potential.
