Muscle cells (aka myofibers or muscle fibers) are made up of bundles of filaments called myofibrils. The filaments contained within these fibrils are made of protein. There are 2 main protein filaments you need to know. Actin is the protein that composes the thin filaments while myosin is the protein that composes the thick filaments.

Aug 24, 2012 · The muscle cells then . contract, or get shorter. Strands of tough connective tissue connect the skeletal muscles to bones. These strands of tissue are called tendons. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. For example, tendons attach the biceps muscle to a bone in your shoulder and to a ...

Smooth muscle cut in cross-section, at high magnification, and stained with a special trichrome stain. The individual muscle cells stain various shades of purple and some have clearly visible centrally placed nuclei. The endomysium surrounding each muscle cell is stained blue here; usually the endomysium is difficult to see in H & E samples.

When a muscle cell is stimulated by a nerve impulse, these myofilaments slide past each other until they completely overlap. This makes the muscle cell shorter and fatter. The more shortened muscle cells there are in a muscle, the greater the contraction of the muscle as a whole. Skeletal muscle
