Which structure supports the eyeball and forms the lateral walls of the orbit?

• A. Zygomatic Bone
• B. Frontal Bone
• C. Occipital Bone
• D. Temporal Bone

Answer: (A)

The zygomatic bone, also known as the cheekbone, plays a crucial role in the structure and support of the eyeball. It forms a significant part of the orbital wall, specifically contributing to the lateral side of the orbit. This positioning helps provide both structural integrity and protection to the eyeball itself, anchoring it in place within the skull. The zygomatic bone's location allows it to also form joints with other facial bones, contributing to the overall architecture of the face and the orbit, and facilitating the complex interactions required for eye movement and function. In contrast, while the frontal bone contributes to the upper portion of the orbit, it does not form the lateral walls. The occipital bone is located at the back of the skull and does not have a direct role in the structure of the orbit. Similarly, the temporal bone, which houses the structures of the inner ear and forms part of the side of the skull, does not contribute to the lateral eye wall. Thus, the function of supporting the eyeball and forming the lateral walls of the orbit is specifically the role of the zygomatic bone.
