Verified step by step guidance

Step 1: Begin by identifying the sphenoid bone, which is a complex bone located at the base of the skull. It plays a crucial role in forming the floor of the cranial cavity and contains several important structures.

Step 2: Understand the optic canal's function. The optic canal is a passageway through which the optic nerve (cranial nerve II) and the ophthalmic artery travel to reach the orbit. It is an important anatomical feature of the sphenoid bone.

Step 3: Review the anatomical regions of the sphenoid bone. The sphenoid bone is divided into several parts: the lesser wing, greater wing, sella turcica, and pterygoid processes. Each region has distinct features and functions.

Step 4: Focus on the lesser wing of the sphenoid bone. The optic canal is located within the lesser wing, which is a thin, triangular projection of the sphenoid bone. This region is positioned near the anterior cranial fossa and contributes to the formation of the orbit.

Step 5: Confirm the correct answer by associating the optic canal with the lesser wing of the sphenoid bone, as this is the anatomical region that contains the optic canal.
