Final answer:
The zygomatic bones are the facial bones that form the cheekbones and contribute to the outer part of the eye socket. They are part of the 14 facial bones that support facial structures and have various functions, including protecting sensory organ cavities.
Step-by-step explanation:
The bones that form the cheekbones and outer part of the eye socket are known as the zygomatic bones. Each paired zygomatic bone contributes significantly to the facial structure by forming much of the lateral wall of the orbit (eye socket) and the lateral-inferior margins of the anterior orbital opening. These bones are not only critical for giving shape to the face but also play a role in protecting the eyes and providing attachment points for facial muscles.
