Spasm Reflex

A spasm is an involuntary contraction or sudden contraction of a muscle in response to some external stimulus. The actions performed by the body as a result of reflex spasms contribute to the normal functioning of organs and tissues. There are several thousand of them in the human body. One of the most striking examples of nervous muscle contraction is protection from danger. Reflexes are innate mechanisms that ensure the body’s adaptation to changing conditions of the external and internal environment. All of them are controlled by the central nervous system, and its response is determined by the perception of what is happening to the person or around him.

Reflex contractions help us carry out movements. For example, when the bladder urges, the urination reflex occurs. A person wakes up from a loud sound or a strong smell. These examples are very typical. We do not notice the contractions themselves, but only the result - the movement. But in humans, not only food and sexual reflexes work flawlessly. The totality of all reactions of the body is called the general reflex (defensive, indicative, escape). It can be caused by the same stimuli in different people, but everyone will react in their own way.
