  2. Myosin head - Wikipedia

    en.wikipedia.org/wiki/Myosin_head

    The myosin head is the part of the thick myofilament made up of myosin that acts in muscle contraction, by sliding over thin myofilaments of actin.Myosin is the major component of the thick filaments and most myosin molecules are composed of a head, neck, and tail domain; the myosin head binds to thin filamentous actin, and uses ATP hydrolysis to generate force and "walk" along the thin filament.

  3. Myosin - Wikipedia

    en.wikipedia.org/wiki/Myosin

    Most myosin molecules are composed of a head, neck, and tail domain. The head domain binds the filamentous actin, and uses ATP hydrolysis to generate force and to "walk" along the filament towards the barbed (+) end (with the exception of myosin VI, which moves towards the pointed (-) end). the neck domain acts as a linker

  4. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:

  5. 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]

  6. Motor protein - Wikipedia

    en.wikipedia.org/wiki/Motor_protein

    Myosin II is an elongated protein that is formed from two heavy chains with motor heads and two light chains. Each myosin head contains actin and ATP binding site. The myosin heads bind and hydrolyze ATP, which provides the energy to walk toward the plus end of an actin filament. Myosin II are also vital in the process of cell division. For ...

  7. Myofibril - Wikipedia

    en.wikipedia.org/wiki/Myofibril

    Energy is released and stored in the myosin head to utilize for later movement. The myosin heads now return to their upright relaxed position. If calcium is present, the process is repeated. When a muscle contracts, the actin is pulled along myosin toward the center of the sarcomere until the actin and myosin filaments are completely overlapped ...

  8. List of skeletal muscles of the human body - Wikipedia

    en.wikipedia.org/wiki/List_of_skeletal_muscles...

    The location of the muscle in a standard human body. The location first specifies a group such as head, neck, torso, upper limbs, or lower limbs, then may have more specific information. However this additional information must be describing location not function. Origin

  9. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    Cross-bridge theory states that actin and myosin form a protein complex (classically called actomyosin) by attachment of myosin head on the actin filament, thereby forming a sort of cross-bridge between the two filaments. The sliding filament theory is a widely accepted explanation of the mechanism that underlies muscle contraction.
