• fibers
  • It is important to understand that having the muscles on diagonals increases the amount of work they can do - a longer muscle can become shorter on contraction than can a shorter, vertical muscle, as it contracts along the full length of the muscle fibers. (yorku.ca)
  • Their fibers are also directed obliquely, but pass in a direction opposite to those of the external intercostal muscles. (wikipedia.org)
  • They are thicker than the internal intercostals, and their fibers are directed obliquely downward and laterally on the back of the thorax, and downward, forward, and medially on the front and are very important Continuation with the external oblique or serratus anterior: A supracostalis muscle, from the anterior end of the first rib down to the second, third or fourth ribs occasionally occurs. (wikipedia.org)
  • arises
  • Each muscle arises from the ridge on the inner surface of a rib, as well as from the corresponding costal cartilage, and is inserted into the inferior border of the rib above. (wikipedia.org)
  • Physiology
  • Eccentric exercises are more challenging than the concentric type, explains the University of California at San Diego on its muscle physiology site. (reference.com)
  • However, research has shown that eccentric contractions are more likely to lead to soreness and injury, according to Muscle Physiology. (reference.com)
  • respiratory
  • Most of the signs of Guedel's classification depend upon the muscular movements (including respiratory muscles), and paralyzed patients' traditional clinical signs were no longer detectable when such drugs were used. (wikipedia.org)
  • This triggers signals from the motor cortex that stimulate the respiratory center of the brain stem, in conjunction with feedback from the proprioreceptors in the muscles and joints of the active limbs. (wikipedia.org)
  • Aerobic training typically improves the endurance of respiratory muscles, whereas anaerobic training tends to increase the size and strength of respiratory muscles. (wikipedia.org)
  • opposite
  • This muscle varies in its attachments, not only in different subjects, but on opposite sides of the same subject. (wikipedia.org)
  • ligaments
  • The pelvis, associated ligaments and muscles provide a floor for the pelvic structures. (wikipedia.org)
  • A complex design of bone, muscle, tendons and ligaments all work together to allow a horse to support the weight of a rider. (wikipedia.org)
  • Hence the entire torso is attached to the shoulders by powerful muscles, tendons, and ligaments. (wikipedia.org)
  • Larynx
  • Stretches of the abdomen, back, neck, and shoulders are important to avoid tension, which influences the sound of the voice through constriction of the larynx and/or breathing muscles. (wikipedia.org)
  • occurs
  • Smooth muscle cells are responsible for helping food pass through the digestive system and for pushing food up into the esophagus when vomiting occurs. (reference.com)
  • relax
  • A good vocal warm up will relax the jaw, while activating the lips and the tongue in a variety of exercises to stretch the muscles and prepare for the more defined vocal articulation that is required when singing or acting. (wikipedia.org)
  • Treat
  • The P.R.I.C.E. formula is the most effective way to treat a strained muscle, according to WebMD - P.R.I.C.E. stands for protect, rest, ice, compress and elevate. (reference.com)
  • What medication is used to treat a pulled muscle? (reference.com)
  • Over-the-counter pain and anti-inflammatory medications, such as ibuprofen and aspirin, can treat most pulled muscles, according to Healthline. (reference.com)
  • back muscles
  • The back muscles play a part in how hard of a pun. (reference.com)
  • A horse that is in good physical condition, with well-developed abdominal and back muscles, will be able to carry more weight for a longer time than one that is not in shape. (wikipedia.org)
  • bend
  • The function of the biceps brachii muscle is to help the arm to bend at the elbow, according to WebMD. (reference.com)
  • groups
  • Stretching helps to activate and prepare the large muscle groups that take care of balance and posture, and the smaller muscle groups that are directly involved with breathing and facial articulation. (wikipedia.org)
  • structures
  • Vocal articulation is controlled by a variety of tissues, muscles, and structures (place of articulation), but can be basically understood as the effects of the lips, the teeth, and the tip of the tongue. (wikipedia.org)
