Areas where the cranial bones have joined together are called:

• A. Sutures
• B. Joints
• C. Cartilage
• D. Ligaments

Answer: (A)

Areas where the cranial bones have joined together are sutures. These are fibrous joints made of dense connective tissue that hold the skull bones together while allowing the skull to grow as a child develops. At birth, sutures are wider and include fontanels, soft spots that let the head pass through the birth canal and accommodate rapid brain growth afterward. As you age, these sutures gradually ossify and the bones fuse into a single, rigid structure. This differs from other joints in the body because sutures are not meant for movement; they’re fixed connections. They’re not cartilage, which would describe a different type of joint, nor ligaments, which connect bones across a joint rather than binding skull bones together.
