Etymology
The term for the area is derived from the
Latin , "smooth", feminine of
glabellus, "hairless".
Function
The glabella is a key anatomical landmark used in craniofacial measurements, including interglabellar distance, which helps assess facial proportions in aesthetics and surgery. It also contributes to facial expressions through the action of muscles like the frontalis and orbicularis oculi.
In medical science
The skin of the glabella may be used to measure
skin turgor in suspected cases of
dehydration by gently pinching and lifting it. When released, the glabella of a dehydrated patient tends to remain extended ("tented"), rather than returning to its normal shape.
