The term 'head bone' is a collective term for the SKULL, occipital, JAW, and hyoid bones. The SKULL is a large bone that forms the head and face, and it is composed of several smaller bones. The occipital bone is located at the back of the SKULL and forms the base of the SKULL. The jawbone is the bone that connects the lower JAW to the SKULL. Finally, the hyoid bone is a small U-shaped bone located in the neck that supports the tongue and helps with swallowing. Together, these four bones form the head bone.
