HOSA Dental Terminology Practice

The term that describes a rounded surface at a bone's articular end is "condyle." Condyles are important structures in the anatomy of long bones, as they form part of a joint and assist in the articulation with another bone. This rounded configuration aids in the smooth movement of joints, allowing for flexion, extension, and other movements depending on the joint type. The presence of a condyle at the articular end facilitates the connection with the corresponding surface of another bone, ensuring stable and functional joint mechanics.

The other terms listed do not relate to the anatomical description of a rounded surface on a bone. Xanthoma refers to a skin condition characterized by yellowish nodules or plaques, often related to lipid metabolism disorders. Mucositis is an inflammatory condition affecting the mucous membranes, typically due to chemotherapy or radiation, and has no relation to bone structure. Hemangioma is a benign tumor made up of blood vessels, which can occur in various tissues, including the skin but is not descriptive of a bone's articular surface.
