What are the four major skull sutures and which bones do they connect?

The four major skull sutures are the coronal, sagittal, lambdoid, and squamous sutures. The coronal suture connects the parietal bones to the frontal bone; the sagittal suture connects the two parietal bones at the midline; the lambdoid suture connects the parietal bones to the occipital bone; and the squamous sutures connect each parietal bone to a temporal bone.

According to the text, the four largest sutures occur where the parietal bones articulate with other cranial bones. The coronal suture is where the parietal bones meet the frontal bone anteriorly. The sagittal suture is where the two parietal bones meet superiorly at the cranial midline. The lambdoid suture is where the parietal bones meet the occipital bone posteriorly. The squamous suture, one on each side, is where a parietal bone and a temporal bone meet on the lateral aspect of the skull.
