Stimulus Nociceptive

Nociceptive type stimulus

Nociceptive stimuli can cause pain of varying degrees of intensity. They can harm tissues or cells of the body and cause a response – a protective one. It follows from this that irritants that are sources of pain are also called pathogens or pathogenic factors.

**Characteristic symptoms of pain:** 1. Pain occurs in a specific area of ​​the body. 2. There is a focus where the pain is felt most acutely. 3. The pain does not subside when you switch attention. 4. As you move away from the source, the pain dulls. 5. When the location of the source changes, a person’s sensations change localization and intensity. 6. Muscle spasm occurs, which contributes to additional tension. As a result, pain appears and intensifies. 7. During the onset of the resting phase, the pain decreases slightly. This is due to the fact that with a decrease in movements, metabolic processes slow down, while immune barriers are noticeably reduced. And also their destruction occurs due to lack of energy and the cell walls and tissues themselves are destroyed. As a result, even greater irritation of the nerve ending occurs and pathology is formed in the tissues.

A nociceptive stimulus is a physical impact of a strong nature that causes pain and discomfort upon contact with certain tissues of the body. Nociceptive stimuli are classified according to the strength and duration of impact on the body surface, as well as the consistency of their appearance. Based on the information presented above, we can say that nociceptive stimuli have a significant negative characteristic and can lead to the destruction of the structure and integrity of various organs of the human body.

It should be noted that the terminology of nociceptive stimulation originates from the Latin “nocere”, which means to damage or suffer. In other words, nociception is the process of perceiving pathological symptoms characteristic of a disease. Such a popular term in medicine refers to the intensity of a person’s perception of pain. The more acute and severe the pain experienced during nociception, the more difficult it is to eliminate it. This concept forms the basis for the assessment of pain, and often becomes the starting point for further therapeutic treatment of pathologies that have pain.
