Final answer:
The angle of the mandible is the rounded corner where the body and ascending ramus meet, closely approaching a 90-degree angle. It features the coronoid and condylar processes, serving as important landmarks in mandibular anatomy.
Step-by-step explanation:
The angle of the mandible refers to the externally rounded corner where the body and the ascending ramus of the mandible meet. The ascending ramus has two significant upward projections: the coronoid process of the mandible, which is a flattened projection from the anterior margin, and the condylar process of the mandible, a thickened projection from the posterior margin. Both the coronoid and condylar processes serve as important attachment points for the muscles of mastication. The angle of the mandible itself is notable in that it is nearly 90 degrees, which is an important consideration in the study of skeletal anatomy and has implications in dental and maxillofacial practices.
