Mandible in a Coronal Section of the Skull, Anterior View

Description

Centered in an anterior coronal section, the mandible is isolated against the remaining facial skeleton, with the body of the jaw spanning left to right beneath the nasal aperture and the orbits. Superiorly, the alveolar process forms the tooth-bearing arch, while the inferior border thickens at the midline into the mental protuberance and paired mental tubercles. The symphysis menti sits on the median plane, and the rami rise posterolaterally toward the temporomandibular joints, partially obscured by the sectioned cranial base and zygomatic region. Clear midline anatomy. Anterior coronal framing makes the mandibular midline and dental arch easy to teach, but it also mirrors the way clinicians evaluate symmetry. Deviations of the symphysis, step-offs along the inferior border, or disruption of the alveolar process are classic cues in mandibular trauma, including parasymphysis fractures that can be missed without a strong sense of normal contours. The relationship of the mandibular arch to the piriform aperture and maxillary dentoalveolar region also supports discussions of occlusal derangement and preoperative planning for orthognathic procedures. Use this asset in gross anatomy and head and neck modules when introducing facial skeletal landmarks, or in dental and maxillofacial curricula to orient students to the mandibular alveolus and chin morphology before moving to CT and panoramic radiography. It also fits atlases, exam-prep figures, and operative overviews that need a clean anterior reference for fracture classification and reduction principles.
