Stimulus Interoceptive

Interoceptive stimuli

Stimuli of interoceptive receptors (R.I.R.) are specific receptors located in the walls of internal organs, tissues and vessels that perceive signals about the state of the internal environment of the body. They are part of the interoreceptor system, which is responsible for regulating the functions of internal organs and maintaining homeostasis.

R.I.R. are divided into mechanoreceptors and chemoreceptors. Mechanoreceptors are pressure, stretch and vibration receptors that are located in the walls of blood vessels, lungs and other organs. Chemoreceptors are receptors for the concentration of gases and electrolytes in the blood, which are located in the walls of blood vessels and in the medulla oblongata.

Irritation of R.I.R. can cause various physiological reactions, including changes in heart rate, respiration, blood pressure, body temperature, etc. For example, when the pressure in a blood vessel increases, the mechanoreceptor sends a signal to the medulla oblongata, which in turn changes the frequency heart rate and blood pressure.

In addition, irritation of R.I.R. plays an important role in regulating the functions of internal organs. For example, chemoreceptors in the walls of blood vessels respond to changes in the concentration of oxygen and carbon dioxide in the blood and send signals to the medulla oblongata to maintain homeostasis.

In general, R.I.R. play an important role in maintaining the homeostasis of the body and regulating the functions of internal organs. They are an important component of the interoreceptor system and can be used to diagnose and treat various diseases.
