What is one of the functions of the occipital bone?

Support for the face
Protection of the brain
Attachment for facial muscles
Connection to the jaw

The correct answer is: Protection of the brain

The occipital bone plays a crucial role in the protection of the brain, as it forms the back and base of the skull. This cranial bone surrounds and encloses the foramen magnum, which is the large opening at the base of the skull that allows the spinal cord to connect to the brain. By encasing the brain tissue, the occipital bone helps shield it from physical trauma and injury. Its structural design, including the presence of a thick, protective layer, is vital for maintaining cranial integrity, thus safeguarding the brain from external forces. Other functions, such as supporting the face, attaching facial muscles, or connecting to the jaw, are primarily associated with different bones in the skull, particularly the facial bones or mandible. The occipital bone's main significance lies in its protective capabilities, making it a critical component of the cranial skeleton.
