Reflex Costal

The costal nerve reflex (also known as the costal reflex or ankylosing spondylitis) is a reflex movement that occurs in response to stimulation of a nerve ending in the costal arch. This reflex plays an important role in maintaining the health and functionality of the chest and can also be useful in diagnosing diseases.

The costal nerve is part of the peripheral nervous system and passes through the costal arch, where it innervates the muscles that are involved in breathing and movement of the chest. When the nerve is stimulated, a reflex muscle contraction occurs, causing the chest to expand and lung capacity to increase. This helps maintain normal lung function and improve ventilation.

In addition, the costal nerve reflex can be used to diagnose various diseases and disorders. For example, if the costal nerve or its branches are damaged, paralysis of the intercostal muscles can occur, which can lead to breathing problems and other serious consequences.

Overall, the costal nerve reflex is an important mechanism that helps maintain chest and lung health and also plays a role in the diagnosis of various diseases.



The costalis reflex is a reflexive contraction of the muscles that are located along the ribs in response to irritation of receptors located in the abdominal cavity. This reflex plays an important role in maintaining correct posture and coordination of movements.

The rib type reflex was first described by Russian physiologist Ivan Bekhterev in 1861. He discovered that when receptors in the abdominal cavity were stimulated, the muscles that run along the ribs contracted. This reflex is one of many reflexes that are involved in regulating body movement and allowing us to maintain balance and coordination.

In order to understand how the rib-type reflex works, you need to know how nerve impulses are transmitted from receptors in the abdominal cavity to the muscles that are located along the ribs. Nerve impulses are transmitted along special fibers called afferent fibers. They begin in the receptors and end in the spinal cord.

When receptors in the abdominal cavity are stimulated, they send nerve impulses along afferent fibers to the spinal cord. In the spinal cord, these impulses are processed and transmitted further to motor neurons, which are located in the anterior horns of the spinal cord. These motor neurons transmit nerve impulses to the muscles along the ribs, causing them to contract.

Thus, the rib type reflex plays an important role in maintaining correct posture and coordination of movement. It allows us to quickly and accurately respond to changes in the environment, ensuring safety and comfort.
