WebMyofibrils run the entire length of the muscle fiber, and because they are only approximately 1.2 µm in diameter, hundreds to thousands can be found inside one muscle fiber. Each myofibril contains repeating units called sarcomeres , which are the actual functional units that cause contraction of a muscle (the “ contractile units “). WebBecause myofibrils are only approximately 1.2 μm in diameter, hundreds to thousands (each with thousands of sarcomeres) can be found inside one muscle fiber. The sarcomere is the smallest functional unit of a skeletal …
