What is the glabella?

The glabella refers specifically to the smooth, elevated area of bone located between the eyebrows, just above the nasal bridge. This anatomical feature is significant in various fields, including medicine and anatomy, as it serves as a landmark for several procedures and assessments. The prominence of the frontal bone in this area contributes to facial structure and is often referenced in discussions pertaining to cosmetic procedures, craniofacial abnormalities, and even in assessing neurological function based on anatomical landmarks.

Other options describe medical conditions or anatomical features that are unrelated to the glabella. For instance, a brain tumor pertains to neoplasms affecting the brain, a mucous discharge from the urethra relates to urinary tract health, and swelling of the tongue concerns oral and dental issues. These terms, while relevant in medical contexts, do not pertain to the specific definition and context of the glabella.
