frontal, parietal, occipital, temporal, sphenoid, ethmoid

sphenoid bone (cranium)

- butterfly shaped bone - sella turkic a or Turks saddle - midline depression - holds the pituitary gland

carotid canal

- located anteriorly to the jugular foramen - allows the passage of the internal carotid artery

occipital bone (cranial)

- posterior bone of the cranium - joins the parietal bones anteriorly at the lamboid suture

mandibular fossa

- receives the mandibular condyle - forms the temporomandibular joint

foramen magnum

A large opening at the base of the skull through which the brain connects to the spinal cord.

hyoid bone

coronal suture

between frontal and parietal bones

squamosal suture

between temporal and parietal bones

temporal bone (cranial)

bones lie inferior to the parietal bones

cleft palate or cleft lip

failure of palatine processes or palatine bone to fuse medially

frontal bone (cranial)

forehead

palatine processes

form the anterior part of the hard palate of the mouth

lacirmal

found in medial walls of each orbit. groove serves as a passageway for tears

occipital condyles

located on each side of the foramen magnum and articulates with the first vertebrae (atlas)

mandible bone (cranium)

lower jaw and largest & strongest bone of the face

mastoid process

round projection on the temporal bone behind the ear

saggital suture
