| processus coronoideus | A sharp triangular projection from a bone; coronoid process of the mandible, the triangular anterior process of the mandibular ramus, giving attachment to the temporal muscle; coronoid process of the ulna, a bracket-like projection from the anterior portion of the proximal extremity of the ulna; its anterior surface gives attachment to the brachialis, its proximal surface enters into the formation of the trochlear notch. Synonym: processus coronoideus. (05 Mar 2000) |

| 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) |

| 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) |
| pars alveolaris mandibulae | The portion of the body of the mandible that surrounds and supports the lower teeth. Synonym: pars alveolaris mandibulae. (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) |
