Coronoid process Condylar process The ramus of mandible is quadrangular in shape and has medial and lateral surfaces Most of the lateral surface provides attachment for the masseter muscle The posterior and inferior borders of the ramus intersect to form the angle of mandible The condylar process is made of: 1 2 1-Head of mandible, participates in forming the Temporomandibular joint and 2-Neck of mandible, which bears a shallow depression (the pterygoid fovea) on its anterior surface Anterior border The anterior border of ramus is sharp and is continuous below with the oblique line on the body of the mandible Body of mandible Alveolar process of mandible Angle of mandible Condylar process Neck Pterygoid fovea Coronoid process Provides attachment for temporalis muscle Mandibular notch Oblique line Mental foramen Mental protuberance Mentum Genio Chin Mandibular foramen Mandibular foramen is the superior opening of the mandibular canal. The inferior alveolar nerve and vessels pass through this foramen. Lingula Lingula is a triangular elevation for attachment of the mandibular end of the sphenomandibular ligament Mylohyoid groove Mylohyoid line Mental foramen transmits mental nerve and vessels Mental spines Digastric fossa Temporomandibular joint -Between the temporal bone of the skull above and the mandible below  Articulation occurs between the articular tubercle and the mandibular fossa of the temporal bone above and the head (condyloid process) of the mandible below The articular surfaces are separated by an articular disc  The articular surfaces are covered with fibrocartilage. Type of Joint The temporomandibular joint is synovial Movements The mandible can be depressed or elevated, protruded or retracted. Rotation can also occur, as in chewing
