  2. Striated muscle tissue - Wikipedia

    en.wikipedia.org/wiki/Striated_muscle_tissue

    The fibres of striated muscle have a cylindrical shape with blunt ends, whereas those in smooth muscle are spindle-like with tapered ends. Striated muscle tissue has more mitochondria than smooth muscle. Both smooth muscle cells and cardiac muscle cells have a single nucleus, and skeletal muscle cells have many nuclei. [6]

  3. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    [2] [3] The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as muscle fibers. [4] The tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. A skeletal muscle contains multiple fascicles – bundles of muscle fibers.

  4. Rhabdomyolysis - Wikipedia

    en.wikipedia.org/wiki/Rhabdomyolysis

    Recurrent or episodic rhabdomyolysis is commonly due to intrinsic muscle enzyme deficiencies, which are usually inherited and often appear during childhood. [10] [13] Many structural muscle diseases feature episodes of rhabdomyolysis that are triggered by exercise, general anesthesia or any of the other causes of rhabdomyolysis listed above. [10]

  5. Anatomical terms of muscle - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_muscle

    Skeletal muscle, or "voluntary muscle", is a striated muscle tissue that primarily joins to bone with tendons. Skeletal muscle enables movement of bones, and maintains posture. [1] The widest part of a muscle that pulls on the tendons is known as the belly.

  6. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    In arthropods there is no smooth muscle. The transversely striated type is the most similar to the skeletal muscle in vertebrates. [4] Vertebrate skeletal muscle tissue is an elongated, striated muscle tissue, with the fibres ranging from 3-8 micrometers in width and from 18 to 200 micrometers in breadth.

  7. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    Skeletal muscle, is a type of striated muscle, composed of muscle cells, called muscle fibers, which are in turn composed of myofibrils. Myofibrils are composed of sarcomeres, the basic building blocks of striated muscle tissue. Upon stimulation by an action potential, skeletal muscles perform a coordinated contraction by shortening each sarcomere.

  8. Rhabdomyoma - Wikipedia

    en.wikipedia.org/wiki/Rhabdomyoma

    A rhabdomyoma is a benign tumor of striated muscle. Rhabdomyomas may be either cardiac or extracardiac (occurring outside the heart). Extracardiac forms of rhabdomyoma are sub-classified into three distinct types: adult type, fetal type, and genital type. Cardiac rhabdomyomas are the most common primary tumor of the heart in infants and children.

  9. Myofilament - Wikipedia

    en.wikipedia.org/wiki/Myofilament

    The protein complex composed of actin and myosin, contractile proteins, is sometimes referred to as actomyosin.In striated skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length in the order of a few micrometers, far less than the length of the elongated muscle cell (up to several centimeters in some skeletal muscle cells).
