What does supraorbital mean?
Supraorbital means situated above the orbit, the bony cavity that contains the eye. The term is most often used in anatomy to describe structures around the brow, including the supraorbital rim, ridge, nerve, and foramen. It also has an important use in physical anthropology and archaeology when describing the degree to which the bone above the eye socket projects forward. A pronounced supraorbital ridge can make the brow area appear more robust, although its form varies greatly among species and individuals. Outside technical contexts, the word is uncommon, but its Latin components make its meaning transparent: 'supra' means above, while 'orbital' relates to the orbit. The term is thus especially useful when precision is needed about the location of a structure immediately above the eye socket.
adjectiveSituated above the eye socket or orbit, especially in reference to the brow, its ridge, nerves, and blood vessels.
- Located or situated above the eye socket or orbit.
- Pertaining to the supraorbital ridge, a bony prominence above the eye socket, especially in the anatomy of primates and other mammals.
"The archaeologist examined the pronounced supraorbital ridge of the skull."
"The surgeon was careful not to damage the supraorbital nerve."
"A pronounced supraorbital ridge is characteristic of the reconstructed skull."
The eyebrow earned its anatomical name by sitting above the orbit: the eye socket beneath it.

Where does supraorbital come from?
The word was formed in the early 19th century from Latin supra, meaning 'above,' and orbitalis, meaning 'of or relating to an orbit.' The underlying Latin noun orbita denotes the eye socket and also gave rise to English orbit and orbital. The prefix-and-root combination entered English as a specialized anatomical term before being extended into descriptions of skulls in comparative anatomy and archaeology.

How supraorbital is actually used
This is primarily a technical anatomical term and is normally used in medical, biological, or archaeological contexts. It is more specific than the general word 'superciliary,' which refers especially to the eyebrow or the region above the eye.
