Stretch Receptor

Stretch Receptor: Role in coordinating muscle contraction and respiratory function

Stretch Receptors are special receptors located between muscle fibers that respond to changes in muscle length. When a muscle is stretched, stretch receptors generate sensory nerve impulses that are transmitted to the central nervous system. Stretch receptors are part of the proprioceptive system, which coordinates muscle contractions and controls body position and movement.

Stretch receptors are important for controlling muscle tension and the force of muscle contraction. When a muscle is stretched, stretch receptors generate signals that are transmitted to the brain and spinal cord. These signals play an important role in regulating muscle tone and the force of muscle contraction.

Stretch receptors also play an important role in respiratory function. In the pulmonary parenchyma, trachea, bronchi and bronchioles, as well as in the atria, there are stretch receptors that respond to changes in the volume of the lungs and heart. Impulses from these receptors are sent to the respiratory or circulatory centers of the medulla oblongata and other parts of the central nervous system. These signals help regulate the rate and depth of breathing and control the heart rate.

Disturbances in the function of stretch receptors can lead to various problems with muscle coordination and respiratory function. For example, dysfunction of stretch receptors can lead to increased muscle tone, which can lead to pain and limited movement. Also, dysfunction of stretch receptors can lead to impaired respiratory function and an increased risk of developing cardiovascular diseases.

In conclusion, stretch receptors play an important role in controlling muscle tension and force of muscle contraction, as well as regulating respiratory function. Dysfunction of stretch receptors can lead to various diseases, so it is important to take care of the health of the muscles and respiratory system.



Stretching is one of the types of stress on muscles and ligaments.

Stretch receptors are located in muscles and ligaments and respond to changes in muscle fiber length. They transmit information to the brain, which then analyzes this information and determines how to properly contract the muscles.

If the muscle strain continues, it can lead to injury. Therefore, it is important to monitor your health and not overload your muscles.



The feeling of muscle stretching is the result of contact of a sensory receptor (stretch receptor) with an external force on the surface of the tense muscle. A stretch can be caused by the movement of a part of the body - passive or active, or it can be observed reflexively in “conveniently” located muscles (for example, the back when bending the neck). The receptors react when the muscle is in a state of tension or spasm. Prolonged tension also causes a delay in the release of tension. This is seen in vertebral artery syndrome (formerly called "vertebral artery syndrome"). Stretching relaxes the muscle and helps reduce pain. But the feeling is growing
