What is another term used to describe the articulations of the skull sutures?

• A. Immovable
• B. Movable
• C. Free-moving
• D. Elastic

Answer: (A)

The term "immovable" is the correct descriptor for the articulations of the skull sutures because these joints, known as sutures, are fibrous joints that do not permit any movement. This immobility is essential for the protection of the brain as it allows for stability in the skull's structure once the cranial bones have fused, typically by early adulthood. The sutures are designed to absorb the shock from impacts while maintaining the integrity of the skull. In contrast, the other terms provided do not accurately represent the nature of the sutures. "Movable" and "free-moving" imply that there is a range of motion at the joints, which is not the case for sutures. "Elastic," while it suggests some flexibility, does not align with the rigid nature of the skull sutures that have fused and provide a fixed structure. Thus, describing the articulations of the skull sutures as immovable accurately reflects their anatomical and functional characteristics.
