In the body, skeletal muscle cells are arranged into bundles (called fascicles) surrounded by thin layers of connective. These fascicles are again arranged into larger bundles, which form the particular muscular organ (i.e. the biceps).
In the case of skeletal muscle, the individual cells (which are also called fibers), ordinarily long and thin, become shorter and fatter under stimulus and take on their tremendous pulling power. Once the stimulus has passed, the muscle relaxes, settling back into its original shape.
Human Skeletal Muscle Cells (SkMC) from PromoCell are isolated from different skeletal muscles (e.g. Musculus Pectoralis Major) of adult single donors.

Smooth muscle cells have a very different appearance than cardiac or skeletal muscle cells. They have one central nucleus, much like cardiac muscles. But smooth muscle cells line the hollow organs in sheets.
Skeletal muscles are usually attached to bones. They are often called striated muscles because of their striated, or striped appearance. The cells of skeletal muscles can be very long, sometimes over 30 cm, and can contain many different nuclei.
Skeletal muscle cells are multinucleated (in fact, they are syncytial) and may have anywhere from ten to hundreds of nuclei. These are all located right up under the plasma membrane (conventionally called the sarcolemma in all types of muscle cells), because the internal volume of the cell is ...

The skeletal muscle cell diagram shows all its part components. The ones most viewed from outside and notice without a microscope are the tendon and muscle belly
The average length of skeletal muscle cells in humans is about 3 cm (sartorius muscle up to 30 cm, stapedius muscle only about 1 mm). Their diameters vary from 10 to 100 µm. Skeletal muscle fibres contain many peripherally placed nuclei. Up to several ...

Sarcoplasmic reticulum is very abundant in skeletal muscle cells and is closely associated with the MYOFIBRILS (and, therefore, the MYOFILAMENTS). The membrane of the SR is well-equipped to handle calcium: there are "pumps" (active transport) ...

Skeletal muscle cells, also referred to as muscle fibers (figure 16-68), are large, multinucleate cells that form by the fusion of precursor cells known as myoblasts (figure 22-41) .
Skeletal muscle cells are multinucleated from the fusion of muscle cells and smooth muscle cells are strictly mononucleated, and cardiac muscle cells are mononucleated in humans. In some animal species, the fetus and post parturition infant most cardiac muscle cells are mononucleated.
