What term describes the joints in the skull?

• A. Planes
• B. Ball and socket
• C. Hinge
• D. Sutures

Answer: (D)

The term that describes the joints in the skull is sutures. Sutures are fibrous joints that firmly unite the bones of the skull and allow for very little movement, which is essential for protecting the brain. They appear as jagged lines on the skull where the different bones have fused together during the developmental stages. Sutures not only contribute to the structural integrity of the skull but also allow for the growth of the skull during childhood. This characteristic of being immovable distinguishes sutures from other types of joints, such as ball and socket or hinge joints, which permit a greater range of motion.
