Convulsions (/kənˈvʌl.ʃənz/) is a medical term used to describe involuntary and violent contractions of the muscles. The word is spelled with a "c" followed by "o-n-v-u-l-s-i-o-n-s". The IPA phonetic transcription shows that the stress is on the second syllable, which is marked by the primary stress symbol (/ˈ/). The "c" is pronounced as a soft "c" sound (/s/), followed by the stressed syllable "vul" pronounced as /vʌl/. The suffix "-sions" is pronounced as /-ʃənz/.
Convulsions are characterized by uncontrollable and involuntary muscle contractions or spasms that occur suddenly and repetitively. It is a term used to describe a variety of physical manifestations that result from abnormal electrical activity in the brain. These abnormal electrical discharges disrupt normal brain functioning, leading to a cascade of symptoms.
Convulsions can range from mild to severe, with varying degrees of intensity and duration. During a convulsive episode, the individual may experience repetitive jerking movements of the limbs, face, or entire body. The muscles may become rigid, causing the person to become stiff and immobile. In more severe cases, convulsions can lead to loss of consciousness.
Convulsions can be indicative of an underlying medical condition such as epilepsy, a neurological disorder characterized by recurrent seizures. However, convulsions can also result from other factors such as high fever (febrile seizures), head injuries, drug reactions, withdrawal from certain substances, or metabolic imbalances.
Medical intervention is often required to manage and treat convulsions, especially if they are recurrent or prolonged. Anticonvulsant medications may be prescribed to control and prevent seizures, while identifying and treating the underlying cause is crucial for long-term management. In emergency situations, ensuring the individual's safety by protecting them from injury during the convulsive episode is a primary concern.
Overall, convulsions refer to the involuntary muscle contractions and spasms that occur due to abnormal electrical activity in the brain and can be a symptom of various medical conditions or triggers.

The word "convulsions" can be traced back to the Latin term "convulsio", derived from the verb "convellere", meaning "to tear loose". This Latin term was formed by combining the prefix "con-" (indicating intensive force) and the verb "vellere" (meaning "to pull" or "to tear"). Over time, "convulsio" came to refer to violent involuntary muscle contractions or spasms associated with various medical conditions. The term was later adopted into English, preserving the original etymology.
