The latchbridge mechanism, found only in smooth muscle, permits smooth muscle cells to remain contracted after calcium has been removed, without further hydrolysis of ATP. This results in a prolonged duration of contraction with low energy requirements. Thus smooth muscle is relatively resistant to fatigue.
WebThe muscle is made up of smaller bundles known as fascicles. Fascicles are actually bundles of individual muscle cells (myofibers or myocytes). These bundles are surrounded by a connective tissue sheath called the perimysium. Each fascicle is made up of several muscle cells known as myocytes. They may also be called myofibers or muscle fibers. WebApr 6, 2024 · Skeletal muscle is therefore made up of hundreds, if not thousands of muscle fibers.
