What does mandibular mean?
Mandibular is a technical adjective meaning relating to the lower jaw or mandible. It is used in anatomy, medicine, dentistry, and associated sciences to identify the structures, nerves, bones, and muscles of this region. For example, the mandibular nerve carries sensation from the lower teeth and supplies motor functions to several muscles involved in chewing, while the mandibular canal runs through the lower jawbone. The adjective is precise where a broader term such as jaw would be less exact. It also has a broader family of derived anatomical terms, including submandibular, meaning below or relating to the lower jaw. Although uncommon in everyday conversation, mandibular is valuable to readers seeking accurate anatomical terminology because it consistently distinguishes structures associated with the lower jaw from those associated with the upper jaw.

Where does mandibular come from?
The English adjective comes from Latin mandibularis, meaning “of or relating to the jaw,” formed from mandibula, the Latin term for the lower jaw. Mandibula is generally connected with Latin mandere, “to chew,” and the same root underlies English cognates such as mandible. The prefix sub- in submandibular was added within English to specify structures situated below the jaw.
