Verified step by step guidance
1
Step 1: Begin by identifying the anatomical location described in the question. The lateral aspect of the skull refers to the side of the skull.
Step 2: Understand the function and position of the bony features listed in the options. For example, the foramen magnum is located at the base of the skull and allows passage of the spinal cord, so it is not relevant to the lateral aspect.
Step 3: Examine the coronal suture, which is a joint between the frontal and parietal bones. It is located on the top of the skull, not the lateral aspect, so it can be ruled out.
Step 4: Consider the mastoid process, which is a bony projection located behind the ear on the temporal bone. While it is on the lateral aspect, it does not form the prominence of the cheek.
Step 5: Focus on the zygomatic arch, which is a bony structure formed by the zygomatic bone and part of the temporal bone. It is located on the lateral aspect of the skull and forms the prominence of the cheek, making it the correct answer.
