Figure 6.3.2 6.3. 2: Muscle type 1) Skeletal muscle cells are long tubular cells with striations (3) and multiple nuclei (4). The nuclei are embedded in the cell membrane (5) to be just inside the cell. This type of tissue occurs in the muscles that are attached to the skeleton.

A. Smooth muscle lacks striations B. All striated mucsle is under voluntary control C. Skeletal muscle fibers are extremely large cells with multiple nuclei D. Skeletal muscle fibers form as multiple precursor cells join to produce a single cell. E. Striated muscle has bands of actin and myosin filaments perpedicular to the length of the cell.Myocytes, sometimes called muscle fibers, form the bulk of muscle tissue. They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue. Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils.Abstract. Many types of large cells have multiple nuclei. In skeletal muscle fibers, the nuclei are distributed along the cell to maximize their internuclear distances. This myonuclear positioning is crucial for cell function. Although microtubules, microtubule associated proteins, and motors have been implicated, mechanisms responsible for ...Striated muscle fibers contain actin and myosin filaments that power contraction and are organized into repeating arrays, called sarcomeres, with a striated microscopic appearance. Cardiac muscle tissue is a striated muscle fiber under involuntary control by the body's autonomic nervous system (ANS). [3]Like skeletal muscles, cardiac muscle cells are striated. Like smooth muscle, they are most often uninucleated (and sometimes binucleated), and their activity is not under conscious control. Some features unique to the heart muscle are branching cells that are linked by intercalated disks.

These results suggest that mammalian striated muscle cells form a single, unified myofibrillar matrix, which provides a direct pathway for both lateral and longitudinal active force generation ...
