What is the function of the glabella?
The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion….

How do you elicit glabellar reflex?
The glabellar reflex is a primitive reflex. It is elicited by tapping the forehead between the eyebrows and nose and observing that the eyes blink. Successive tapping of the glabella eventually leads to habituation with blinking being suppressed.
Is the glabella a depressor?
The “glabellar complex” often refers to a group of the brow-associated muscles (mostly depressors in action) that function primarily for facial expression.
Is glabella a bone?
The glabella is the smooth midline bony prominence between the supraciliary arches of the frontal bone, representing the most anterior part of the forehead when standing erect and looking straight ahead. The metopic suture traverses the glabella, between the two frontal bones.
Where on the body is the glabella?
Glabellar lines or glabella lines appear in the glabella, the skin over your forehead, between and above the eyebrows and right above the nose. When you wrinkle your face by talking, yawning, laughing, or making expressions, the glabella is the skin most affected by the muscle activity beneath the surface.
What does a positive glabellar reflex mean?
Definition. A type of primitive reflex that is elicited by repetitive tapping on the forehead. Normal subjects usually blink in response to the first several taps, but if blinking persists, the response is abnormal and considered to be a sign of frontal release.
What is Dysport injections?
Dysport (abobotulinumtoxin A) is an injection for wrinkle treatment. This noninvasive procedure temporarily decreases muscle movement in the target areas to soften the appearance of glabellar lines, the vertical wrinkles most prominent on your forehead in between your eyebrows.
Where is glabella?
forehead
Your “glabella” is the skin on your forehead, between your eyebrows and above your nose. When you make facial expressions, that skin is moved by the muscles on your forehead.
How does glabella work?
Our wearable glasses prototype Glabella incorporates optical sensors to continuously measure and store the user’s pulse waves at three different sites on their face.
Is there any variation in functional anatomy of the glabella?
There is a large amount of variation in functional anatomy of glabella. Example: When most people frown, they primarily bring their brows together as well as depress them. However, this is not done by everyone. Some people predominantly frown in a vertical form, intensely depressing their brows.
How does glabella measure pulse waves?
Our wearable glasses prototype Glabella incorporates optical sensors to continuously measure and store the user’s pulse waves at three different sites on their face.
Is abnormal habituation of the glabellar reflex useful as a diagnostic tool?
While research on the utility of an abnormal habituation of the glabellar reflex have been limited, most studies point to the physical exam finding being better correlated with an advanced stage of a neurodegenerative condition rather than as a diagnostic tool.
