|---|---|
| biventer mandibulae | <anatomy> One of the suprahyoid group of muscles consisting of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin, by posterior belly from the digastric groove medial to the mastoid process; insertion, by anterior belly into lower border of mandible near midline; action, elevates the hyoid when mandible is fixed; depresses the mandible when hyoid is fixed; nerve supply, posterior belly from facial, anterior belly by nerve to the mylohyoid from the mandibular division of trigeminal, a muscle with two fleshy bellies separated by a fibrous insertion. Synonym: musculus digastricus, biventer mandibulae, musculus biventer mandibulae, two-bellied muscle. (05 Mar 2000) |
| canalis mandibulae | The canal within the mandible that transmits the inferior alveolar nerve and vessels. Its posterior opening is the mandibular foramen. Synonym: canalis mandibulae, inferior dental canal. (05 Mar 2000) |
| caput mandibulae | The expanded articular portion of the condylar process of the mandible. Synonym: caput mandibulae. (05 Mar 2000) |
| ramus mandibulae | The upturned perpendicular extremity of the mandible on either side; it gives attachment on its lateral surface to the masseter muscle. Synonym: ramus mandibulae. (05 Mar 2000) |
| ramus marginalis mandibulae nervi facialis | <anatomy, nerve> Branch of facial nerve which parallels the mandibular margin innervating risorius muscle and muscles of lower lip and chin. Synonym: ramus marginalis mandibulae nervi facialis. (05 Mar 2000) |
| collum mandibulae | The constricted portion of the condylar process below the head of the mandible. Synonym: collum mandibulae. (05 Mar 2000) |
| musculus biventer mandibulae | <anatomy> One of the suprahyoid group of muscles consisting of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin, by posterior belly from the digastric groove medial to the mastoid process; insertion, by anterior belly into lower border of mandible near midline; action, elevates the hyoid when mandible is fixed; depresses the mandible when hyoid is fixed; nerve supply, posterior belly from facial, anterior belly by nerve to the mylohyoid from the mandibular division of trigeminal, a muscle with two fleshy bellies separated by a fibrous insertion. Synonym: musculus digastricus, biventer mandibulae, musculus biventer mandibulae, two-bellied muscle. (05 Mar 2000) |
| corpus mandibulae | The heavy, U-shaped, horizontal portion of the mandible extending posteriorly to the angle where it is continuous with the ramus; it supports the lower teeth. Synonym: corpus mandibulae. (05 Mar 2000) |
| symphysis mandibulae | The fibrocartilaginous union of the two halves of the mandible in the foetus; it becomes an osseous union during the first year. Synonym: symphysis mandibulae, symphysis mentalis, symphysis menti. (05 Mar 2000) |
| incisura mandibulae | The deep notch between the condylar and coronoid processes of the mandible. Synonym: incisura mandibulae, sigmoid notch. (05 Mar 2000) |
| foramen mandibulae | The opening into the mandibular canal on the medial surface of the ramus of the mandible giving passage to the inferior alveolar nerve, artery, and vein. Synonym: foramen mandibulae, inferior dental foramen. (05 Mar 2000) |
| linea obliqua mandibulae | The line on the external surface of the mandible that extends from the mental tubercle to the ramus and separates the alveolar and basilar parts of the bone. Synonym: linea obliqua mandibulae. (05 Mar 2000) |
| lingula mandibulae | A pointed tongue of bone overlapping the mandibular foramen, giving attachment to the sphenomandibular ligament. Synonym: lingula mandibulae, mandibular tongue, Spix's spine. (05 Mar 2000) |
| arcus | Synonym: arch. Origin: L. A bow (05 Mar 2000) |
