Questions: The orbits of the eyes are formed by . cranial bones only facial bones only several facial and cranial bones

The answer is the third one: several facial and cranial bones.

Explanation:

• The orbits of the eyes are complex structures that are formed by a combination of both cranial and facial bones.
• Specifically, the bones that contribute to the formation of the orbits include the frontal bone (a cranial bone), the sphenoid bone (a cranial bone), the zygomatic bone (a facial bone), the maxilla (a facial bone), the palatine bone (a facial bone), the lacrimal bone (a facial bone), and the ethmoid bone (a cranial bone).
• Therefore, the correct answer is that the orbits are formed by several facial and cranial bones, as they involve contributions from both categories.
