Week One: Skull Bones

Vomer Bone

a long, flat bone that joins with the ethmoid bone to create the nasal spectrum.

Temporal Bone

a temporal bone on each side of the skull joins the parietal bone along the squamosal suture.

Sphenoid Bone

butterfly-shaped bone; houses the pituitary gland; base of the skull; in front of temporal bone

Occipital Bone

forms the back of the skull and the base of the cranium right behind the parietal bones.

Frontal Bone

forms the front portion of the skull above the eyes and includes the forehead, the roof of the nasal cavity, and the roofs of the eye sockets.

Ethmoid Bone

located in front of the sphenoid bone. It consists of two masses, one on each side of the nasal cavity. These form sections of the nasal cavity and eye sockets.

Nasal Bones

oblong bones that vary in size and form in different individuals. They lie side by side between the frontal processes of the maxillary bones and join to form the bridge of the nose.

Parietal Bone

one is located on each side of the skull just behind the frontal bone. It has four borders and is shaped like a curved plate. Together, they make the roof of the cranium.

Zygomatic Bones

responsible for the cheeks below and the sides of the eyes. Helps form lateral walls and floors of orbits.

Inferior Nasal Conchae

scroll-shaped thin bones making up lateral part of nasal cavity; the membranes lining them help to filter and warm air

Palatine Bones

situated in the back of the nasal cavity between the maxilla and the pterygoid process.

Mandible

the lower jaw bone, consists of a horizontal horseshoe-like body with a flat ramus projecting upward at each end.

Lacrimal Bones

thin, scale like structure located in the middle wall of each eye socket between the ethmoid bone and the maxilla.

Maxillae

forms the upper-jaw and is the keystone of the face. All other immovable bones are connected to this. Makes up the front of the roof of the mouth, floors of the orbits, and sides of the nasal cavity.
