The spelling of the word "sulcus orbitalis" is based on its roots in Latin. "Sulcus" refers to a groove or furrow, while "orbitalis" relates to the orbit or eye socket. In IPA phonetic transcription, the word is pronounced /ˈsʌlkəs ɔrˈbaɪtəlɪs/. The accent is on the second syllable, and the "s" sound is followed by a short "u" sound. The "orbitalis" part of the word is pronounced with a long "o" sound before the "r" sound. Overall, the word describes an anatomical feature of the eye socket.
The sulcus orbitalis, also known as the orbital sulcus or the medial orbital sulcus, is a term used in human anatomy to describe a specific groove or depression found in the bony structure of the skull called the orbit. The orbit is the cavity that houses the eyeball and its associated structures.
The sulcus orbitalis is located on the medial wall of the orbit, which is the side closest to the midline of the face. It is a shallow groove that runs parallel to the medial margin of the orbit, extending from the anterior to the posterior part of the orbit. The sulcus orbitalis marks the anatomical landmark of the ethmoidal process of the inferior nasal concha.
This particular anatomical feature has importance in clinical practice, as it plays a crucial role in the drainage of tears from the eye. The sulcus orbitalis acts as a pathway for the nasolacrimal duct, which carries tears from the eye to the nasal cavity. The structure of the sulcus orbitalis provides stability to the nasolacrimal duct and prevents it from being compressed or obstructed, ensuring the continuous flow of tears.
In summary, the sulcus orbitalis refers to the groove found on the medial wall of the orbit, which serves as a pathway for the nasolacrimal duct. It plays a vital role in tear drainage and is an essential anatomical structure of the human skull.
Orbital s., one of a number of irregularly disposed fissures on the inferior surface of each frontal lobe of the cerebrum, dividing it into the orbital gyri.

The word "sulcus" comes from the Latin term "sulcus", which means groove or furrow. "Orbitalis" is derived from the Latin word "orbis", meaning circle or ring, and refers to the orbit or eye socket. Hence, the term "sulcus orbitalis" can be translated to mean the groove or furrow of the eye socket.
