What is the term for involuntary muscle contractions?

The term for involuntary muscle contractions is "muscle spasms." Muscle spasms refer to sudden and involuntary contractions of a muscle or group of muscles. These contractions can vary in severity and duration, sometimes causing significant discomfort or pain. They can happen due to various factors, including dehydration, overuse of a muscle, or as a result of certain medical conditions.

In contrast, muscle cramps—though similar in nature to spasms—are typically more intense and often occur during physical activity or due to electrolyte imbalances. Muscle tears and muscle strains involve damage to muscle fibers but do not specifically refer to involuntary contractions. Instead, they involve injury due to overstretching or excessive force. Understanding the distinction between these terms helps clarify both the causes and the implications of involuntary muscle contractions.
