Which statement is true about immovable joints?

Which statement is true about immovable joints?

• A. They connect bones that move a lot
• B. They allow little to no movement
• C. They are found only in the limbs
• D. They provide shock absorption

Answer: (B)

Immovable joints are joints that connect bones with dense connective tissue to restrict movement. They are designed for stability and protection, not motion. A classic example is the sutures of the skull, where skull bones are tightly bound together, and the tooth sockets (gomphoses) where teeth are held in place with minimal to no movement. This is why the idea that they allow little to no movement is true—their purpose is to keep the bones firmly in place. The other statements don’t fit because they describe features of joints that do move, or functions not characteristic of immovable joints. Immovable joints are not limited to the limbs, and their main role isn’t shock absorption, which is more associated with cushioning cartilage in joints that permit movement.
