tetanic contraction

But when I straightened him out there were no signs of tetanic contractions.

If stimuli are delivered at high frequency, then the twitches will run together, resulting in tetanic contraction.

Tetanic contractions are characteristic of poisoning by strychnine.

If the stimulation is long enough, the muscle reaches peak force and plateaus at this level, resulting in a tetanic contraction.

This is a popular state equation applicable to skeletal muscle that has been stimulated to show Tetanic contraction.

In cases such as this, the sustained contraction lacks any relaxation, and it is called a tetanic contraction.

This antagonistic poison will predispose someone to tetanic contractions, and can prove fatal if the diaphragm becomes involved.

Skeletal muscle contractions can be broadly separated into twitch and tetanic contractions.

(Tonic contractions are also known as tetanic contractions).

Twitch contractions following tetanic contractions were potentiated only at short sarcomere lengths (22 C).

It is important to point out that our posttetanic twitch contractions were obtained at a variety of lengths after a tetanic contraction at optimal length.

The first twitch contraction was obtained 30 s after the tetanic contraction, and the subsequent twitches were collected with 10 s intervals.

The force-length relationship observed in this study is consistent with previous investigations on the force-length relation for fixed-end tetanic contractions of skeletal muscle.

These factors are likely to be more evident after the tetanic contraction (75 pulses per s) than after staircase (10 pulses per s).

A tetanic contraction (also called tetanized state or tetanus) occurs when a motor unit has been maximally stimulated by its motor neuron.

The force-length relation for tetanic contractions had a descending limb, which was deviated to the right when compared to the theoretical force-length relation.

Inhomogeneity has been shown to occur during tetanic contractions elicited on the descending limb of the force-length relation [ 18 19 ] .

The depression of twitch amplitude after a tetanic contraction may be a consequence of hydrogen ion or inorganic phosphate (Pi) accumulation.

The initial electric burst is very short, containing only 10-64 pulses, but is still strong enough to cause tetanic contraction in the body of the prey fish, often breaking its vertebral column.

Force-sarcomere length relation of tetanic contractions The force-sarcomere length relation for tetanic contractions is presented in Figure 1.

As well as being caused by tetanus (lockjaw), after which they are named, tetanic contractions are a symptom of hypoparathyroidism, due to an underdeveloped parathyroid, or injury to the parathyroid.

In studying posttetanic potentiation, the length tension relation for twitch contractions was obtained with sequential contractions at different lengths, both prior to and after a tetanic contraction at optimal length.

Tetanic contraction may be observed following the use of a device intended to apply transcutaneous electrical muscle stimulation (EMS) through skin contact electrodes for the purpose of improving abdominal muscle tone.

Electrophysial functional mapping (EFM), a tool utilized in both methods in order to verify the target nuclei, has come under scrutiny due to its associated risks of hemorrhages, dysarthria or tetanic contractions.

It is generally considered that the enhancement of DT during staircase and following a tetanic contraction occurs as a result of phosphorylation of the regulatory light chains of myosin [ 4 5 ] .
