Tetanic response definition biology

images tetanic response definition biology

Tetanic contraction can exist in a variety of states, including isotonic and isometric forms—for example, lifting a heavy box off the floor is isotonic, but holding it at the elevated position is isometric. This occurs when a muscle's motor unit is stimulated by multiple impulses at a sufficiently high frequency. The clinical manifestations of tetanus are caused when tetanus toxin blocks inhibitory nerve impulses, by interfering with the release of neurotransmitters. This leads to unopposed muscle contraction and spasm. Views Read Edit View history. Voluntary sustained contraction is a normal physiologic process as in the crouching or box-holding examplesbut involuntary sustained contraction exists on a spectrum from physiologic to disordered pathologic.

Muscles often exhibit some level of tetanic activity, leading to muscle tonein order to maintain posture; [7] for example, in a crouching position, some muscles require sustained contraction to hold the position.

    Tetanus, also known as lockjaw, is a severe infection caused by a bacterium that affects the brain and nervous system.

    The bacterium usually. An unfused tetanus of a motor unit (MU) evoked by a train of pulses at variable interpulse intervals is the sum of non-equal twitch-like responses to these to model the twitch (see Fig 2 for definitions of these parameters).
