Lessons on the cranial bones of the skull and their markings.
The Sphenoid bone is a butterfly-shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones.
The temporal bones are facial bones which located at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex.
The occipital bone is an unpaired bone, which covers the back of the head. It is the only cranial bone to articulate with the cervical spine.
The frontal bone is a cranial bone that surrounds and protects the anterior portion of brain. Learn about the different markings of the frontal bone.
The ethmoid bone is a cuboid-shaped cranial bone that is located at the top of the nasal cavity, between the two orbits and it is anatomically divided into three parts: a horizontal cribriform plate, a perpendicular plate, and two ethmoidal labyrinths.
The parietal bone is a large, thin, four-sided cranial bone that makes up much of the top and sides of the cranium. Learn about the different markings of the parietal bone.

Sutures are junctions between adjacent bones of the skull which are rigidly held together by fibrous connective tissue.
Ethmoid bone: (lamina cribrosa ethmoidalis).
Temporal bone: or temporal squama (pars squamosa; squama temporalis).
