Verified step by step guidance

Step 1: Understand the anatomy of the human skull. The skull is composed of several bones connected by immovable joints called sutures. These sutures are named based on the bones they connect.
Step 2: Identify the location of the parietal bones and the frontal bone. The parietal bones are located on the sides and top of the skull, while the frontal bone forms the forehead and the upper part of the eye sockets.
Step 3: Learn the names and positions of the sutures. The sagittal suture runs along the midline of the skull, separating the two parietal bones. The lambdoid suture separates the parietal bones from the occipital bone at the back of the skull. The squamous suture is located on the sides of the skull, connecting the parietal bones to the temporal bones. The coronal suture separates the parietal bones from the frontal bone.
Step 4: Match the description in the question to the correct suture. The question asks for the suture that separates the parietal bones from the frontal bone. Based on the anatomical information, this is the coronal suture.
Step 5: Confirm your understanding by visualizing or referencing a diagram of the human skull to see the coronal suture's position between the parietal and frontal bones.
