Spasm means which of the following?

• A. Involuntary contraction
• B. Seizure
• C. Tremor
• D. Convulsion

Answer: (A)

Spasm means a sudden, involuntary contraction of a muscle or a group of muscles. This focuses on the muscle action itself, which is what the term describes. A seizure involves abnormal brain electrical activity and can lead to convulsions, but that’s a brain-based event rather than just a muscle contraction. A tremor is a rhythmic shaking, not a single involuntary contraction. A convulsion is a rapid sequence of muscle contractions typically seen during a seizure, which is a broader pattern than a single spasm.
