Compare: bronchoconstriction. /bronÂ·choÂ·spasm/ (brongÂ´ko-spazm) bronchial spasm; spasmodic contraction of the smooth muscle of the bronchi, as in asthma.pasm. 1. a sudden involuntary contraction of a muscle or group of muscles. 2. a sudden, transitory constriction of a passage, canal, or orifice; spasms usually occur when the nerves supplying muscles are irritated, and are often accompanied by pain.
Contractions are initiated by the calcium-activated phosphorylation of myosin rather than calcium binding to the troponin complex that regulates myosin binding sites on actin in skeletal and cardiac muscle. Contractions in vertebrate smooth muscle are initiated by agents that increase intracellular calcium.urthermore, if the muscle length shortens, the contraction is concentric. But if the muscle length lengthens, then the contraction is eccentric. In natural movements that underlie locomotor activity, muscle contractions are multifaceted as they are able to produce changes in length and tension in a time-varying manner.
