The image shows a left lateral view of a skull, with the orbit towards the left side of the image and the occipital bone towards the right side of the image. The lambdoid suture is a fused fibrous joint on the posterior surface of the skull found at the junction between the occipital bone and the two parietal bones. However, the blue arrow points to the pterion, the H-shaped suture at the junction between the frontal bone anteriorly, sphenoid bone inferiorly, temporal bone posteriorly and parietal bone superiorly.

The image shows a left lateral view of a skull, with the orbit towards the left side of the image and the occipital bone towards the right side of the image. The blue arrow points to the pterion, the H-shaped suture at the junction between the frontal bone anteriorly, sphenoid bone inferiorly, temporal bone posteriorly and parietal bone superiorly. It is a clinically important point because immediately underneath lies the middle meningeal artery. A fracture of the pterion can result in laceration of the middle meningeal artery, which in turn may result in an epidural haemorrhage.

QuestionChoice
The image shows a left lateral view of a skull, with the orbit towards the left side of the image and the occipital bone towards the right side of the image. The asterion is an anatomical point on the lateral aspect of the skull, created by the junction between the occipital bone posteriorly, the temporal bone anteriorly and the parietal bone superiorly. However, the blue arrow points to the pterion, the H-shaped suture at the junction between the frontal bone anteriorly, sphenoid bone inferiorly, temporal bone posteriorly and parietal bone superiorly.

The image shows a left lateral view of a skull, with the orbit towards the left side of the image and the occipital bone towards the right side of the image. The coronal suture is a fused fibrous joint of the superior surface of the skull found at the junction between the frontal and parietal bones. However, the blue arrow points to the pterion, the H-shaped suture at the junction between the frontal bone anteriorly, sphenoid bone inferiorly, temporal bone posteriorly and parietal bone superiorly.

QuestionChoice
The image shows a left lateral view of a skull, with the orbit towards the left side of the image and the occipital bone towards the right side of the image. The sagittal suture is a fused fibrous joint of the superior surface of the skull found in the midline at the junction between the right and left parietal bones. However, the blue arrow points to the pterion, the H-shaped suture at the junction between the frontal bone anteriorly, sphenoid bone inferiorly, temporal bone posteriorly and parietal bone superiorly.
