Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils.Thank goodness! These cells are striated as skeletal muscle fiber is, however, they are branched, typically binucleate (two nuclei), and have intercalated disks.

Answer <p> False</p> Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor —a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has ... Muscle: The Three Types of Muscle. Contractility is a fundamental property of cells and the majority of them contain essentially the same contractile machinery as that found in muscle cells. In muscle cells, however, a larger proportion of the cells' resources are given over to this function than in other cell types.Cardiac muscle is able to contract and relax, unlike skeletal muscles which only contract. This means that cardiac tissue will have far more irregular shapes than skeletal muscles. Cardiac muscle cells contain T tubules that connect to the sarcoplasmic reticulum which stores the calcium ions needed for the contraction of the cell.Striated muscles are highly organized tissues ( Fig. 1) that convert chemical energy to physical work.
