Skeletal Muscle/Músculo Esquelético

En esta lección vamos a hablar sobre los dos tipos de músculo esquelético, que son músculo esquelético rápido, también conocido como el músculo esquelético blanco, y el músculo esquelético lento, o rojo.

  • Insertion

    a tendon that fixates the muscle to the bone; highly moveable end of muscle that performs most of the work as a muscle contracts

  • Origin

    a tendon that fixates the muscle to the bone; stationary end of the muscle that performs little to no movement

  • Myofibrils

    long chains of contractile proteins called myofilaments that are located within muscle cells (myocytes)

  • Skeletal muscle

    a form of muscle that contains very long, striated, multinucleated cells; skeletal muscles are the largest form of muscles in the body and attached to the skeleton; these are used for the movement of our bones, generate heat and protect deeper internal organs; skeletal muscles are also the most abundant type of muscle found in the human body
