Reflex Motor-Visceral

The motor-visceral reflex (r. motorius-visceralis) is one of the main reflexes that controls the activity of the internal organs and systems of the body. This reflex is responsible for coordinating movements and maintaining body balance.

The motor-visceral reflex reflex is a physiological mechanism that allows the body to adapt to various environmental conditions. It allows a person to maintain balance and stability during movement, as well as control the functioning of internal organs.

The main components of the motor-visceral reflex arc are:

– Sensory receptors that are located in muscles, ligaments and joints. They respond to changes in body position and transmit information to the central nervous system.
– Motor neurons, which are located in the spinal cord and send signals to the muscles and internal organs.
– Internal organs that respond to signals from motor neurons and perform specific functions.

One example of a motor-visceral reflex is the cough reflex. When we cough, it is because receptors in the trachea and bronchi respond to irritants such as dust or smoke. These signals are transmitted to the central nervous system, which then sends signals to motor neurons that cause the diaphragm and abdominal muscles to contract. This causes muscles to contract, which push air out of the lungs, causing a cough.

Another example of a motor-visceral reflex is the sneezing reflex. Receptors in the nose respond to various irritants, such as smoke, dust or allergens, and transmit signals to the central nervous system. The central nervous system then sends a signal to motor neurons, which contract the muscles responsible for opening the nostrils and closing the airways.
