  2. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    The sliding filament theory was born from two consecutive papers published on the 22 May 1954 issue of Nature under the common theme "Structural Changes in Muscle During Contraction". Though their conclusions were fundamentally similar, their underlying experimental data and propositions were different.

  3. Posterior compartment of leg - Wikipedia

    en.wikipedia.org/wiki/Posterior_compartment_of_leg

    Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments: Plantarflexes ankle independent of position of knee; steadies leg on foot

  4. Sarcomere - Wikipedia

    en.wikipedia.org/wiki/Sarcomere

    Skeletal muscles are composed of tubular muscle cells (called muscle fibers or myofibers) which are formed during embryonic myogenesis. Muscle fibers contain numerous tubular myofibrils . Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands.

  5. Mylohyoid line - Wikipedia

    en.wikipedia.org/wiki/Mylohyoid_line

    Rarely, the mylohyoid muscle may originate partially from other surfaces of the mandible. [2] The posterior (back) part of this line, near the alveolar margin , gives attachment to a small part of the superior pharyngeal constrictor muscle , and to the pterygomandibular raphe .

  7. 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]

  8. Fascial compartment - Wikipedia

    en.wikipedia.org/wiki/Fascial_compartment

    A fascial compartment [1] is a section within the body that contains muscles and nerves and is surrounded by deep fascia.In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial compartments of the forearm contain an ...

  9. Fascial compartments of leg - Wikipedia

    en.wikipedia.org/wiki/Fascial_compartments_of_leg

    The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
