Frontal Bone
Large bone of the skull that forms the top of the head and forehead; Forehead
Occipital Bone
Bone that forms the lower back portion of the skull; beneath the Parietal Bone
Temporal Bone
Large bone forming the base and sides of the skull
Ethmoid Bone
Irregular bone of the face attached to the sphenoid bone
Sinus Cavities
Help decrease the weight of the skull, include:
Frontal - Above eyebrows
Ethmoid - Near center bone (Ethmoid Bone)
Maxillary - Located on either side of the nose
