    Study Notes

    The Cranium

    • Composed of 8 bones: Sphenoid (1), Temporal (2), Ethmoid (1), Parietal (2), Occipital (1), Frontal (1).

    Frontal Bone

    • Type: Flat bone with three parts: squamous, orbital, and nasal.
    • Located at the front of the cranium, articulates with Parietal bones, Ethmoid bone, lacrimal bones, Maxillae, Nasal bones, Zygomatic bones, and Sphenoid bone.
    • Blood supply is from the middle meningeal artery.
    • Functions include providing structure to the skull, eye orbits, and upper face; protecting the frontal lobe of the brain; and aiding in facial expressions.

    Parietal Bones

    • Type: Flat bones.
    • Composed of frontal, occipital, sphenoidal, and mastoid angles.
    • They articulate with the frontal bone, occipital bone, temporal bone, and sphenoid bone.
    • Blood supply is from the middle meningeal artery.
    • Main functions include providing structure to the cranial cavity.

    Occipital Bone

    • Type: Flat bone with three parts: squamous, basilar, and lateral.
    • Located at the posterior base of the skull, articulates with parietal bones, temporal bones, sphenoid bone, and atlas.
    • Blood supply also comes from the middle meningeal artery.
    • Functions include providing structural support, attachment for muscles, and forming the foramen magnum, which allows passage for the spinal cord.

    Temporal Bones

    • Type: Irregular bones with components including Squamous, Petrous, Tympanic, Mastoid, and Styloid parts.
    • They articulate with parietal, occipital, and zygomatic bones.
    • Important for protecting auditory structures and supporting the sides of the skull.
