AND PRONUNCIATIONS A spasm is a sudden, involuntary contraction of a muscle, a group of muscles, or a hollow organ such as a heart, or a similarly sudden contraction of an orifice. It most commonly refers to a muscle cramp which is often accompanied by a sudden burst of pain, but is usually harmless and ceases after a few minutes.

Muscle contraction Muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.

The A to Z of Medical Terms There are a variety of other causes of involuntary muscle contractions, which may be more serious, depending on the cause. The word spasm may also refer to a temporary burst of energy, activity, emotion, eustress, stress, or anxiety unrelated to, or as a consequence of, involuntary muscle activity. spasm is a sudden, involuntary contraction of a muscle, a group of muscles, or a hollow organ such as a heart, or a similarly sudden contraction of an orifice.

Labor Contractions Labor contractions are the periodic tightening and relaxing of the uterine muscle, the largest muscle in a woman's body. Something triggers the pituitary gland to release a hormone called oxytocin that stimulates the uterine tightening.thers say the contraction feels like pressure in the back. During a contraction, the abdomen becomes hard to the touch. In the childbirth process, the work of labor is done through a series of contractions.

Define expand & contract (science)? Expansion is An increase in the volume of a substance while its mass remain the same. Expansion is usually due to heating. When substances are heated the molecular bonds between there particles are weakened and particle (atoms) move faster causing substance to expand. Contraction is just opposite to expansion in which particles (atoms) move closer to each other.

contraction isotonic contraction muscle contraction without appreciable change in the force of contraction; the distance between the muscle's origin and insertion becomes lessened. lengthening contraction a muscle contraction in which the ends of the muscle move farther apart, as when the muscle is forcibly flexed.ourglass contraction contraction of an organ, as the stomach or uterus, at or near the middle. isometric contraction muscle contraction without appreciable shortening or change in distance between its origin and insertion. Isotonic (A) and isometric (B) contraction.

muscle contraction muscle contraction. the process of force-generation in the fibres of any class of muscle, by the interaction of myosin head-groups in the thick filaments with actin molecules in one of the immediately neighbouring thin filaments.oncentric muscle contraction acceleration force generated within contracting agonist muscle tissue, by actin/myosin interaction; agonist muscle force overcomes antagonist muscle resistance, creating a net reduction in length of agonist muscle (see entry above).

Contractions Contractions, which are sometimes called ‘short forms’, commonly combine a pronoun or noun and a verb, or a verb and not, in a shorter form. Contractions are usually not appropriate in formal writing. We make contractions with auxiliary verbs, and also with be and have when they are not auxiliary verbs.

What is Muscle Contraction? Through the process of muscle contraction, tension is developed within muscle tissue, which may or may not lead to movement of a part of the body. The term contraction often means to shorten; however, during a muscle contraction the tension may cause muscles to stay the same, get longer or become shorter.The physical process of the contraction happens quickly and in only a few steps.nstead, a muscle contraction of smooth or cardiac muscle is initiated within the organ itself. Within the digestive system, the introduction of food is what causes the contractions to move the food through the system.

- • CONTRACTION (noun). The noun CONTRACTION has 4 senses: 1. (physiology) a shortening or tensing of a part or organ (especially of a muscle or muscle fiber). 2. the process or result of becoming smaller or pressed together.

Muscle contraction Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.f the muscle length changes while muscle tension remains the same, then the muscle contraction is isotonic. In an isotonic contraction, the muscle length can either shorten to produce a concentric contraction or lengthen to produce an eccentric contraction.

- The definition of contraction is the lengthening or shortening of a muscle fiber or a word formed by combining the sounds of two longer words.1  An example of a contraction is the action of the uterus during the birth process. 2  An example of a contraction is the word doesn't from does not.ontraction-Computer Definition. The shortening of a word or phrase by omitting letters or syllables. In the English language, a contraction generally, but not always, marks the omitted letters or syllables with an apostrophe or a period. Telco, for example, is a contraction of telephone company.

eccentric contraction lengthening contraction eccentric contraction. postural contraction the state of muscular tension and contraction that just suffices to maintain the posture of the body. segmental c's muscular contractions of the small intestine that serve to mix and transport chyme. shortening contraction concentric contraction.ccentric contraction, a type of muscle contraction that occurs as the muscle fibers lengthen, such as when a weight is lowered through a range of motion. The contractile force generated by the muscle is weaker than an opposing force, which causes the muscle to stretch.
