Spasmodic contractions of voluntary muscles throughout the body

• A. Seizure
• B. Epilepsy
• C. Convulsion
• D. Tremor

Answer: (C)

Spasmodic contractions of voluntary muscles throughout the body describe a convulsion. A convulsion is the sudden, involuntary, often jerky or stiff movement of muscles that can involve the whole body and is the motor manifestation that can occur during a seizure. The broader event is called a seizure, which is the abnormal electrical activity in the brain that can produce convulsions, altered awareness, or other symptoms. Epilepsy refers to a condition characterized by recurrent seizures. Tremor, by contrast, is a rhythmic, oscillating movement that is usually more regular and not the abrupt, widespread muscle contractions described here. So the term that best captures those sudden, widespread muscle contractions is convulsion.
