In the torso there are several major muscle groups including the pectoral, and abdominal muscles intrinsic and extrinsic muscles are subdivisions of muscle groups in the hand, foot, tongue, and extraocular muscles of the eye. Muscles are often classed as groups of muscles that work together to carry out an action. Most muscles occur in bilaterally-placed pairs to serve both sides of the body. There are more than 600 skeletal muscles in the human body, making up around 40% to 50% of body weight. These chemical reactions produce adenosine triphosphate (ATP) molecules that are used to power the movement of the myosin heads. Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers. The myofibrils are composed of actin and myosin filaments called myofilaments, repeated in units called sarcomeres, which are the basic functional, contractile units of the muscle fiber necessary for muscle contraction. Muscle fibers are in turn composed of myofibrils. Muscle fibers also have multiple mitochondria to meet energy needs. In these cells the nuclei termed myonuclei are located along the inside of the cell membrane. Muscle fibers are formed from the fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. Each individual fiber, and each muscle is surrounded by a type of connective tissue layer of fascia. Ī skeletal muscle contains multiple fascicles – bundles of muscle fibers. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system. Skeletal muscles are voluntary muscles under the control of the somatic nervous system.
The muscle tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. DOES NOT work with our relocated upper control arm.Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. ******This kit is designed to work with a conventional upper control arm, anything longer or shorter will NOT work.
