  2. Syncytium - Wikipedia

    en.wikipedia.org/wiki/Syncytium

    A classic example of a syncytium is the formation of skeletal muscle.Large skeletal muscle fibers form by the fusion of thousands of individual muscle cells. The multinucleated arrangement is important in pathologic states such as myopathy, where focal necrosis (death) of a portion of a skeletal muscle fiber does not result in necrosis of the adjacent sections of that same skeletal muscle ...

  3. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    Diagram of skeletal muscle fiber structure. Skeletal muscle cells are the individual contractile cells within a muscle and are more usually known as muscle fibers because of their longer threadlike appearance. [10] Broadly there are two types of muscle fiber performing in muscle contraction, either as slow twitch or fast twitch .

  4. Sarcoplasm - Wikipedia

    en.wikipedia.org/wiki/Sarcoplasm

    [1] [2] [3] The calcium ion concentration in sarcoplasma is also a special element of the muscle fiber; it is the means by which muscle contractions take place and are regulated. [ 4 ] [ 5 ] The sarcoplasm plays a critical role in muscle contraction as an increase in Ca 2+ concentration in the sarcoplasm begins the process of filament sliding.

  5. Sarcomere - Wikipedia

    en.wikipedia.org/wiki/Sarcomere

    A sarcomere (Greek σάρξ sarx "flesh", μέρος meros "part") is the smallest functional unit of striated muscle tissue. [1] It is the repeating unit between two Z-lines. Skeletal muscles are composed of tubular muscle cells (called muscle fibers or myofibers) which are formed during embryonic myogenesis.

  6. Neuromuscular junction - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction

    A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber. [1] It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction. [2] Muscles require innervation to function—and even just to maintain muscle tone, avoiding atrophy.

    When you exercise vigorously, muscle fibers are damaged and the hot water can increase blood flow, which helps the muscles repair themselves and become stronger, said the study’s lead author ...

  8. Dystrophin - Wikipedia

    en.wikipedia.org/wiki/Dystrophin

    Dystrophin is a protein located between the sarcolemma and the outermost layer of myofilaments in the muscle fiber . It is a cohesive protein, linking actin filaments to other support proteins that reside on the inside surface of each muscle fiber's plasma membrane (sarcolemma). These support proteins on the inside surface of the sarcolemma in ...
