WebJun 8, 2024 · Myofibril Structure. Each myocyte can contain many thousands of myofibrils. Myofibrils run parallel to the myocyte and typically run for its entire length, attaching to the sarcolemma at either end. Each myofibril is surrounded by the sarcoplasmic reticulum, which is closely associated with the transverse tubules. ...

WebJan 1, 2024 · Each myofibril is marked by regularly spaced bands (striations) along its length. In relaxed muscle, a single repeat of this pattern is about 2 µm long (the length varies with degree of contraction) and is called a sarcomere. Because the striations on adjacent myofibrils are usually aligned, the entire muscle fiber appears uniformly striated.
