Corneopterygoid reflex

The root reflex is a reflexive movement of the cheek muscles that appears when pressure is applied to the eyeball. It occurs due to the fact that the nerve passing through the zygomatic bone connects with the nerve bundle that moves the zygomatic muscle. This reflex got its name because during its study, contractions of the zygomatic muscles are observed when pressing on the eyeballs, and this state lasts about a second or a fraction of a second and does not return to the normal state of the eye and muscles.

The reflex is an important element in the perception of light by the eyes and allows the visual system to prepare for further work with the environment when the lighting changes. When studying this reflex, the strength of contraction of the muscles involved in its formation is determined - zygomatic or chewing. Using a reflex study, the condition of the main areas of the nervous system is assessed. Results after diagnosis can help determine the main cause of this pathology. The result may be increased due to unnecessary examination of the peripheral area of ​​the face. It can also be reduced due to insufficient research and identification of the causes that provoked this condition. It is worth paying attention to the fact that the correlation of the study results is between strength indicators and reaction time. The research is carried out only by a highly qualified specialist to avoid additional errors.

Corneopterogoid reflex

The corepterangoid reflex is a complex unconditioned reaction consisting of involuntary tension or relaxation of the masticatory muscles in response to a blow to the pterygoid process of the sphenoid bone. The lateral pterygoid muscle contracts first. The effect occurs with the participation of the mandibular nerve. In English-language literature, this reflex is also called “pterygoid myotatic reflex”, and its characteristics, almost coinciding with the Russian-language concept, differ only in one aspect: muscle tension quickly develops and disappears, while in Russian literature only a short-term effect is spoken of.

It would be incorrect to assume that the reflexes of the maxillofacial region fully correspond to the reflex patterns of the myotatotic reflex subtype. Undoubtedly, the reflex manifestations of all reflexes of the maxillofacial region are closely connected by the general regulatory system of the central nervous system - they all serve to maintain homeostasis of the oral cavity, jaws as its organs.

We can highlight a number of main aspects of the neurophysiological support of certain reflex reactions of the maxillofacial area:

Eye and ear A clinometer of corporal landmarks (cracks, points of reflection), with the help of which, even before birth, differences in the length of the dura vault in space are determined or these differences are assessed on opposite sides of the body, are called visual tractions. Feedback of the “eye-hand” type is the use of “optokinetic” reflex reaction processes to stimulate eye accommodation and exercise the extraocular muscles. Motor impulses from the limbs of the eye ensure the return of the eyeball to its normal, neutral position at the end of the “wide working posture”. Triggers fire short proprioceptive impulses that control the contact position of the entire body. More attention was paid to the study of swimming reflexes, since these types of movements are the most common in water and therefore have the greatest importance in swimming. At the same time, individually different types of responses to stimuli were identified, as well as motor phenomena that make it possible to individualize a person’s functional reserves. From here arose the concept of individual types of locomotion, which play a significant role in learning to swim. In addition, with specific
