  2. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    Sliding filament theory: A sarcomere in relaxed (above) and contracted (below) positions. The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. [1]

    The sarcomere then shortens which causes the muscle to contract. [3] In the skeletal muscles connected to tendons that pull on bones, the mysia fuses to the periosteum that coats the bone. Contraction of the muscle will transfer to the mysia, then the tendon and the periosteum before causing the bone to move.

  4. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Sliding filament theory: A sarcomere in relaxed (above) and contracted (below) positions. The sliding filament theory describes a process used by muscles to contract. It is a cycle of repetitive events that cause a thin filament to slide over a thick filament and generate tension in the muscle. [22]

  5. Diad - Wikipedia

    en.wikipedia.org/wiki/Diad

    The z-line defines the borders of each sarcomere and act as the connection point between the thin filaments. The t-tubules and sarcoplasmic reticulum are used in conjunction to receive and direct the calcium ions and cause contraction. Once contracted, the clear H-zone between the actin filaments disappears as the filaments move towards each other.

  6. Luxating patella in dogs: Symptoms, causes and how to help - AOL

    Arthritis is a natural consequence of a luxating patella, and can cause dogs to be very painful, which may require euthanasia. When the patella luxation is more serious, dogs need surgery, and if ...

  7. 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 .

  8. Muscle cell - Wikipedia

    This in turn causes the muscle cell to relax. [28] There are four main types of muscle contraction: isometric, isotonic, eccentric and concentric. [29] Isometric contractions are skeletal muscle contractions that do not cause movement of the muscle. and isotonic contractions are skeletal muscle contractions that do cause movement.

    Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
