Glabellar reflex

The glabellar reflex (lat. reflex glabellaris) is one of the primitive unconditioned reflexes of humans. It involves blinking your eyes in response to tapping on the glabella (the area between the eyebrows above the bridge of the nose).

This reflex appears in newborns and disappears by 4-6 months of life. It belongs to the so-called archaic reflexes, which are observed in the early stages of development, but are then suppressed as the central nervous system matures.

Preservation of the glabellar reflex in adults may indicate brain damage, in particular, in diseases such as encephalitis, meningitis, and brain tumors. Therefore, in neurology, its presence or absence is used as one of the diagnostic signs.

Thus, the glabellar reflex is a primitive unconditioned reflex, characteristic of newborns and disappearing in the first months of life. Its persistence into adulthood may indicate brain pathology.

The glabellar reflex is one of the important human reflexes. It is responsible for maintaining balance and stability when walking. The glabellar reflex can be impaired as a result of various injuries or diseases. One common glablar reflex disorder is von Willebrand's disease.

According to the materials, glabellar reflux is an active posture in which a person maintains tension in the muscles of the face, neck and upper shoulder girdle in order to achieve stabilization of balance while maintaining balance during all head movements.

With reflux disorders, vertical glabellaria may lead to problems with coordination of movement when standing, walking, and manipulating loose objects. Also, reflux disorders can manifest as symptoms of impaired attention and concentration, balance, headache and dizziness.

The glabellar reflex corresponds to the activation of systems: the vestibular apparatus, cerebellar mechanisms, glabellar muscles, the posterior parts of the cervical spinal cord, and the direct parts of the body.
