Laryngospasm is described by which term?

• A. Inflammation of the vocal cords
• B. Narrowing of the bronchial tubes
• C. Spasmodic closure of the vocal cords
• D. Dilation of the glottis

Answer: (C)

Laryngospasm is the sudden, involuntary contraction of the muscles around the larynx that causes the vocal cords to snap shut. This spasmodic closure can block airflow, leading to partial or complete airway obstruction, which is why it’s a critical concern during anesthesia or throat irritation. The term itself comes from the larynx and spasm, highlighting the abrupt, protective tightening of the vocal cords. This is different from inflammation of the vocal cords, which involves swelling and hoarseness rather than a rapid, forceful closure. It also isn’t about the bronchial tubes (that would be bronchospasm) or about widening the opening (dilation of the glottis), which would increase airflow rather than impede it.
