Verified step by step guidance

Understand the anatomy of the orbit: The orbit is the bony cavity that houses the eye and its associated structures. It is formed by contributions from several bones, including the sphenoid bone.

Identify the sphenoid bone's location and role: The sphenoid bone is a complex bone located at the base of the skull. It contributes to the posterior wall of the orbit, as well as other structures in the cranial cavity.

Analyze the options provided: The inferior wall, lateral wall, and medial wall of the orbit are formed by other bones such as the maxilla, zygomatic, and ethmoid bones, respectively. The posterior wall is primarily formed by the sphenoid bone.

Correlate the sphenoid bone's anatomical position with the posterior wall: The posterior wall of the orbit is adjacent to the sphenoid bone's greater wing and lesser wing, which are key components of the bone's structure.

Conclude that the posterior wall of the orbit is formed primarily by the sphenoid bone, based on its anatomical location and structural contribution.
