Question

Quizplus · Accepted Answer

A convulsion is a type of seizure that involves involuntary muscle contractions, which are controlled by the motor cortex in the brain. This is different from other types of seizures, such as absence seizures (previously known as petit mal seizures) that do not involve convulsions and are characterized by a brief loss of consciousness. Oxygen deprivation or toxic chemicals may trigger seizures, but they do not necessarily cause convulsions. Loss of consciousness can occur with convulsions, but it is not a defining characteristic.
