WebFeb 7, 2024 · Myofibrils are made of sarcomeres How Do Actin and Myosin Work? Actin and myosin work together to produce muscle contractions and, therefore, movement. First, a motor neuron delivers an electrical signal to the muscle cell from the brain. This triggers the release of a chemical called acetylcholine. WebMyofibrils make up a large proportion of the muscle cell. These organelles constitute over 80% of the volume of the muscle cell. Up to 85% of the water in a muscle cell is held in the myofibrils. Much of that water is held by capillary forces arising from the arrangement of the thick and thin filaments within the myofibril. download irs documents https://wheatcraft.net
