SUPRAORBITAL REFLEX Meaning and
Definition
-
The supraorbital reflex is a neurological response characterized by the contraction of muscles near the forehead region above the eye. It is triggered by the stimulation of the supraorbital nerve, which is a sensory nerve located in the upper part of the face, specifically around the forehead and eyebrow area. This reflex is a type of protective response that occurs in reaction to a sudden or unexpected touch or impulse on the supraorbital region.
When the supraorbital nerve is stimulated, such as by a light tap or pressure applied to the forehead, it sends an electrical signal to the brain. The brain then processes this signal and initiates a reflex action that causes the muscles near the stimulated region to contract or twitch. The contraction can be seen as a slight upward movement of the eyebrow or a wrinkling of the forehead.
The supraorbital reflex is considered a part of the normal range of neurological responses in humans. It is an innate reflex, meaning it does not require conscious thought or voluntary control, but rather occurs automatically as a result of the nerve's stimulation. This reflex can be used by healthcare professionals as a diagnostic tool to assess the integrity and sensitivity of the supraorbital nerve and associated neural pathways.

Etymology of SUPRAORBITAL REFLEX
The word "supraorbital" comes from two Latin roots: "supra", meaning "above", and "orbis", meaning "circle" or "eye". "Supraorbital" refers to something that is located above the orbit or eye socket.
The term "reflex" comes from the Latin word "reflexus", which means "backward reflection". In anatomy and physiology, a reflex is an involuntary response or action that is automatically triggered by a specific stimulus, typically a sensory signal.
Therefore, the etymology of "supraorbital reflex" indicates a reflex action that is triggered by a stimulus above the eye socket or orbit.
