Reflex Cochleopupillary

The cochleo-pupillary reflex is one of the reflexes that is responsible for the reaction of the pupil to sound. It was discovered in 1865 by French physiologist Claude Bernard and German physiologist Hermann von Helmholtz.

The reflex is that when a sound appears, the pupil dilates, and when it disappears, it contracts. This reflex is important for the survival of animals, as it allows them to quickly react to danger and avoid it.

The mechanism of the cochleopupillary reflex is associated with the work of the auditory nerve and nerve cells in the brain. When sound reaches the cochlea in the ear, it stimulates nerve cells that transmit information about the sound to the brain. In response, the brain sends signals to the muscles of the pupil, which begin to contract or dilate.

In addition, the cochleopupillary reflex can be used to diagnose various diseases of the nervous system. For example, impairment of this reflex may indicate damage to the auditory nerves or brain.

In general, the cochleopupillary reflex plays an important role in our lives and is one of the key mechanisms that help us adapt to the environment.

Reflex cochleopollarcum Introduction. Reflexes are the body's innate ability to respond to external stimuli. They can be classified according to various criteria, such as place of occurrence, duration of action, etc. One type of reflex is cochleopapillary.

Description of the cochlepolylic reflex. The cochleopartial reflex is the abduction of the eye when the cochlear receptors are irritated. The name comes from the Greek word "cochlea" - snail, and the Latin "pupilla" - pupil. The mechanism of the reflex is that when the sound intensifies, the auditory cortex sends impulses to the lower horizontal layer and transmits it to the muscles responsible for abducting the eyes. As a result, the eyeballs are observed to abduct during loud sounds - that is, the pupils of the eyes remain motionless. This allows the body not to focus on sound waves, but to record their direction.
