Which of the following bones is part of the eye socket?

The frontal bone is part of the eye socket, also known as the orbit. It contributes to the superior portion of the eye socket, forming the forehead and playing a crucial role in protecting the eyes and their associated structures. The orbit itself consists of several bones, including the frontal, zygomatic, maxilla, lacrimal, ethmoid, sphenoid, and palatine bones, which create a complex structure that supports and houses the eye.

In contrast, the humerus, femur, and radius are long bones found in the limbs. The humerus is located in the upper arm, the femur is the thigh bone, and the radius is one of the two bones in the forearm. None of these bones contribute to the anatomy of the eye socket, making them irrelevant to this particular question. Understanding the specific roles of cranial and facial bones in forming various anatomical structures is essential in anatomy.
