Definition


A spasm is a muscle contraction that can affect an entire muscle group, one muscle alone, or even solely one fibrous tissue bundle. Voluntary command muscles can go into spasm, which is when we observe cramps or convulsions, yet this term is also sometimes employed for automatic muscles, notably those of the digestive system, in which case the spasm is involuntary and of short duration. There are different types of spasm, including those affecting the cheeks, abdominal spasms generally accountable for pain or cramps, spasms in muscle flexion associated with juvenile epilepsy, and so on.
