    A paired cranial bone forming the superior and lateral sides of the skull.
  • Frontal bone
    The bone forming the forehead and the upper part of the eye sockets.
  • Glabella
    The smooth area between the eyebrows on the frontal bone.
  • Frontonasal suture
    The joint between the frontal bone and the nasal bones.
  • Supraorbital foramen (notch)

  • Sphenoid bone (greater wing)
    A butterfly-shaped bone forming part of the base of the skull and the sides of the orbits.
  • Temporal bone
    Bone located at the sides and base of the skull, housing structures of the ear.
  • Optic canal
    A passage in the sphenoid bone through which the optic nerve passes.
  • Ethmoid bone
    A light, spongy bone located between the eyes that forms part of the nasal cavity and the orbits.
  • Middle nasal concha
    A thin, curved bony plate on the ethmoid bone that helps filter and humidify air.
  • Perpendicular plate
    Part of the ethmoid bone forming the superior portion of the nasal septum.
  • Inferior nasal concha
    A separate bone that forms part of the lateral walls of the nasal cavity.
  • Lacrimal bone
    Small bone forming part of the medial wall of the orbit, near the tear ducts.
  • Zygomatic bone
    The cheekbone, forming the prominence of the cheeks and part of the orbit.
  • Infraorbital foramen
    An opening in the maxilla below the orbit for nerves and blood vessels.
  • Maxilla
    The upper jaw bone that holds the upper teeth and forms part of the orbit and nasal cavity.
  • Vomer
    A thin, flat bone forming the inferior part of the nasal septum.
  • Mandible
    The lower jaw bone, the largest and strongest facial bone.
  • Mental foramen
    An opening on the anterior surface of the mandible allowing passage of nerves and vessels.
  • Mandibular symphysis
