Which term corresponds to a joint where two bones are grown together?

Explanation:
Fusion of two bones into a single bone is called synostosis. When the joint space ossifies and the bones become one, there’s no movable joint at that site. That specific condition—complete bone fusion—is what the term synostosis describes. By comparison, synarthrosis refers to an immovable joint in general, a synchondrosis is a cartilaginous joint held by hyaline cartilage (often temporary during growth), and syndesmosis is a fibrous joint connected by ligaments, typically allowing some movement. So synostosis is the correct term for two bones grown together.
