  2. Muscles of respiration - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_respiration

    The involvement of these muscles seems to depend on the degree of respiratory effort. During quiet breathing, the scalenes are consistently physically active, while the sternocleidomastoids are quiet. [5] With an increase in the respiratory volume, sternocleidomastoids also become active. [6]

  3. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [ 1 ] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle ) can be completely autonomous.

  4. Work of breathing - Wikipedia

    en.wikipedia.org/wiki/Work_of_breathing

    The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

  5. Organ system - Wikipedia

    en.wikipedia.org/wiki/Organ_system

    Plants have two major organs systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists stems, leaves, and the reproductive parts of the plant (flowers and fruits). The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. The root system ...

    For this reason, the two systems are combined and studied as the neuroendocrine system. The same is true for the musculoskeletal system because of the relationship between the muscular and skeletal systems. Cardiovascular system: pumping and channeling blood to and from the body and lungs with heart, blood and blood vessels.

  8. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    Part of the training process is learning to relax the antagonist muscles to increase the force input of the chest and anterior shoulder. Contracting muscles produce vibration and sound. [74] Slow twitch fibers produce 10 to 30 contractions per second (10 to 30 Hz). Fast twitch fibers produce 30 to 70 contractions per second (30 to 70 Hz). [75]

    en.wikipedia.org/wiki/Soft_palate

    The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate .
