muscle contractionThe movement of muscle fibres in response to force or load.
Muscle contraction types
• Concentric—The muscle shortens in length as it overcomes resistance.
• Eccentric—The muscle increases in length to accommodate resistance.
• Isometric—The muscle resists outside stress without exhibiting motion.
a drawing together; a shortening or shrinkage.
ventricular muscle contraction during early systole after closure of the atrioventricular valves and before the semilunar valves open; the muscle continues to contract, forcing up the ventricular pressure without any change in the ventricular volume.
individual myocardial cells transmit motor impulses across cell boundaries and act as a syncytium.
the stage in wound healing when there is centripetal movement of surrounding tissues and the area of the wound decreases. This is believed to be a cell-mediated phenomenon, involving myofibroblasts.
the state of muscular tension and contraction that just suffices to maintain the posture of the body.
striated muscle contraction
tetanic contraction, tonic contraction
sustained muscular contraction with alternating relaxation.
