Which term describes joints with no movement?

• A. Amphiarthosis
• B. Synarthrosis
• C. Diarthrosis
• D. Synovial joint

Answer: (B)

Joints that allow no movement are called synarthroses. This classification describes immobile joints, typically fibrous or cartilaginous, that bind bones tightly so there’s no detectable motion. Classic examples are the sutures between skull bones and the gomphosis between a tooth and its socket. In contrast, amphiarthroses allow a little motion, and diarthroses are freely movable joints. The term synovial joint refers to a structural group of joints that are diarthrotic, featuring a synovial cavity and smooth movement, not immobility.
