Orbital bone

Supraorbital ridge of the frontal bone

Zygomatic bone

Frontal bone

Verified step by step guidance

Step 1: Begin by identifying the anatomical location of the eyebrow and the curved line of the eye socket. The eyebrow is located above the eye, and the curved line of the eye socket is part of the bony structure surrounding the eye.

Step 2: Understand the term 'supraorbital ridge.' The supraorbital ridge is the bony prominence located above the orbit (eye socket) and is part of the frontal bone.

Step 3: Review the anatomy of the frontal bone. The frontal bone forms the forehead and the upper part of the eye sockets, including the supraorbital ridge.

Step 4: Compare the other options provided: The orbital bone refers to the bones forming the eye socket collectively, not a specific ridge. The zygomatic bone forms the cheekbone and contributes to the lateral wall of the orbit but does not include the supraorbital ridge.

Step 5: Conclude that the natural arch of the eyebrow follows the supraorbital ridge, which is part of the frontal bone. This ridge provides structural support and defines the shape of the eyebrow area.
