muscleösszehúzódásokkal
muscleösszehúzódás is the Hungarian term for muscle contraction. This is a fundamental biological process that allows for movement in living organisms. Muscle contraction occurs when muscle cells, known as muscle fibers, shorten. This shortening is primarily driven by the interaction of two protein filaments within the muscle fiber: actin and myosin.
The process is initiated by a nerve impulse, which triggers a release of calcium ions within the
There are different types of muscle contractions. Isotonic contractions involve a change in muscle length and
