Study Notes
The Mandible and Facial Bones: Key Features
- The mandible is a single bone with mirrored halves joined by a fibrous symphysis at birth, which ossifies during the first year.
- The mandible has a U-shaped body/corpus, a mental symphysis, and mental tubercles at the point of the chin.
- The alveolar arch of the mandible contains a dental alveolus for each tooth, while the mandibular rami are quadrilateral plates extending upward from the body.
- The mandible has a mandibular foramen, mental foramen, mylohyoid line, and superior border containing a coronoid and condylar process.
- The articulatory function of the mandible includes housing the lower teeth and contributing to speech through tongue attachment and oral cavity modifications during movement.
- Nasal bones form the bridge of the nose and lie medially to the frontal process of maxillary bones.
- Palatine bones are relatively small, contributing to the formation of nasal, oral, and orbital cavities and the velum attachment.
- Lacrimal bones and zygomatic bones contribute to the orbital cavity and have specific articulations with other bones.
- The inferior nasal conchae is a separate bony structure located on the vertical nasal septum.
- The vomer bone is the posterior part of the nasal septum, dividing the nasal cavity.
- The cranium, or brain case, is comprised of eight bones, including the frontal, parietal, occipital, and temporal bones, as well as the ethmoid and sphenoid bones.
- The sphenoid bone, which connects to all other bones of the cranium, forms in the middle of the skull and is the only bone that connects to all other bones of the cranium.
