Glabella

Glabella (pronounced gluh-bel-uh)

(1) In human anatomy, a smooth elevation of the frontal bone just above the bridge of the nose: a reference point (as the craniometric point) in physical anthropology or craniometry; the most forward projecting point of the forehead in the midline of the supraorbital ridges; known also as the mesophryon.

(2) In zoology, the axial protuberance on the cephalon of certain arthropods (especially trilobites).

1590s: From the New Latin, either feminine singular or neuter plural of the adjective glabellus (without hair; smooth) from the Latin glaber (smooth, bald), from the Proto-Italic ɣlaðros, from the primitive Indo-European gladh (smooth).  The construct was glaber (without hair, smooth) + -lus, the diminutive adjective and noun suffix.  Use in medicine and pathology began in the 1820s, the use in zoology began with the study of the trilobite in 1849.  Glabella is a noun and glabellar is an adjective; the "correct" noun plural is glabellae but the more common modern alternative is glabellas.
