What are the major sutures of the skull?

The major sutures of the skull include the coronal, sagittal, lambdoid, and squamous sutures, which are crucial for understanding the structure and formation of the skull. The coronal suture is located at the front of the skull, where the frontal bone meets the parietal bones. The sagittal suture runs along the midline, dividing the left and right parietal bones. The lambdoid suture is found at the back of the skull, connecting the parietal bones with the occipital bone. The squamous suture, situated on the sides of the skull, connects the parietal bones to the temporal bones. These sutures are key features that define the boundaries of the different cranial bones and are instrumental in the overall architecture of the skull.

The other options listed contain bones that are not primarily defined by sutures of the skull. For instance, the frontal, maxillary, nasal, and lacrimal options do not represent major cranial sutures but rather refer to facial bones. The occipital, parietal, temporal, and zygomatic grouping mixes cranial and facial bones without emphasizing the key sutures. Lastly, the ethmoid, sphenoid
