The joint that cannot move at all is a suture. Sutures are immovable joints found in the skull. These joints are responsible for connecting the bones of the skull together, forming a strong and rigid structure to protect the brain.
Examples of sutures include:
- Coronal suture: Connects the frontal bone to the parietal bones.
- Sagittal suture: Connects the two parietal bones.
- Lambdoid suture: Connects the parietal bones to the occipital bone.
While other types of joints, such as synovial joints, allow for a wide range of movement, sutures are designed to remain rigid and prevent any movement. This rigidity is crucial for providing a secure and protective environment for the brain.
