Answer:

The answer is - Tetany

Explanation:

Tetany is a sustained contraction which can either be fused (one smooth sustained contraction plateau) or unfused (incomplete due to wavering contraction). Tetany occurs when the muscle contracts uncontrollably and can also be as a result of electrolyte imbalance such as low calcium, magnesium deficiency, low potassium. When the sarcomeres are stimulated so quickly causing a sustained contraction it is called tetany.

Answer: TETANY

Explanation: Generally,TETANY (tetanic seizure) is a medical sign or condition that is characterised by intermittent involuntary muscle spasm/contraction.

Tetany is caused by malfunction of the parathyroid gland(leading to low level of calcium in the blood) and a subsequent deficiency of calcium(hypocalcemia).

Symptoms of tetany are spasms of the hands and feet, cramps, spasm of the voice box (larynx), and overactive neurological reflexes.

TETANY can also be caused magnesium and potassium deficiency.

Treatment of tetany is with intravenous or oral administration of calcium to replace the deficiency in the blood and the administration of vitamin D supplements.

<h3>What are vital signs?</h3>

The term vital signs in the field of medicine refers to the measurement of the basic functions of the body. The basic function of the body is usually four in number, these are: body temperature, blood pressure, breathing rate, and pulse rate.

The body temperature refers to the degree of hotness or coldness of the human body. The measurement is done using a thermometer.
