  3. Sarcomere - Wikipedia

    en.wikipedia.org/wiki/Sarcomere

    Myosin filaments, the thick filaments, are bipolar and extend throughout the A-band. They are cross-linked at the centre by the M-band. The giant protein titin (connectin) extends from the Z-line of the sarcomere, where it binds to the thick filament (myosin) system, to the M-band, where it is thought to interact with the thick filaments. Titin ...

  4. Striated muscle tissue - Wikipedia

    en.wikipedia.org/wiki/Striated_muscle_tissue

    The main function of striated muscle tissue is to create force and contract. These contractions in cardiac muscle will pump blood throughout the body. In skeletal muscle the contractions enable breathing, movement, and posture maintenance. [1] Contractions in cardiac muscle tissue are due to a myogenic response of the heart's pacemaker cells ...

  5. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. [1] According to the sliding filament theory, the myosin ( thick filaments ) of muscle fibers slide past the actin ( thin filaments ) during muscle contraction, while the two groups of filaments ...

  6. 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). [5]

  7. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    In skeletal muscles, muscle spindles convey information about the degree of muscle length and stretch to the central nervous system to assist in maintaining posture and joint position. The sense of where our bodies are in space is called proprioception , the perception of body awareness, the "unconscious" awareness of where the various regions ...

  8. Myofibril - Wikipedia

    en.wikipedia.org/wiki/Myofibril

    In striated skeletal and cardiac muscle tissue the actin and myosin filaments each have a specific and constant length on the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells). The filaments are organized into repeated subunits along the length of the ...

  9. Frank–Starling law - Wikipedia

    en.wikipedia.org/wiki/Frank–Starling_law

    The Frank-Starling mechanism occurs as the result of the length-tension relationship observed in striated muscle, including for example skeletal muscles, arthropod muscle [4] and cardiac (heart) muscle. [5] [6] [7] As striated muscle is stretched, active tension is created by altering the overlap of thick and thin filaments. The greatest ...
