Goes through the inside of the orbit from left to right
What is the arrow pointing to?
Orbit
Eyeball sits interior
What is the arrow pointing to?
Zygomatic Bone
Think of the cheek for the location; lateral to the maxilla
What is the arrow pointing to?
Vomer
Thin bridge inside the nasal cavity; along the median line
What is the arrow pointing to?
Mandible
Bottom of the jaw contains the only movable joint in the skull; inferior to everything; bottom teeth
What is the arrow pointing to?
Maxilla
Inferior and lateral to nasal but medial to zygomatic
What is the arrow pointing to?
Nasal Bone
Elastic cartilage; inferior to frontal bone and superior to maxilla
What is the arrow pointing to?
Temporal bone
Rest of cheek bone; lateral to sphenoid and zygomatic and inferior to parietal
What is the arrow pointing to?
Coronal Suture
Divides frontal from parietal; soft spot for babies
What is the arrow pointing to?
Parietal
In the lateral view it is superior to the temporal bone + squama
What is the arrow pointing to?
Temporal squama
Btwn parietal & temporal
What is the arrow pointing to?
Temporal Bone
Above the ear
What is the arrow pointing to?
Zygomatic process
Aligned with temporal squamos, it protrudes out (hence process)
What is the arrow pointing to?
Occipital Bone
Posteior to frontal and posterio-medial to parietal
What is the arrow pointing to
External occipital protuberence
sharp ridge separating dorsal surface from the nuchal line
What is the arrow pointing to?
Mastoid Process
Found under the ear
What is the arrow pointing to?
Occipital condyle
What is the arrow pointing to?
Mandible
What is the arrow pointing to?
Zygomatic arch
Arch formed from the temporal bone and zygomatic bone
What is the arrow pointing to?
Sagittal suture
Sagittal meaning midline so it is btwn. left and right parietal bone
What is the arrow pointing to?
External Occipital Protuberence
Big bump on the back of the head; posterior; located on the occipital bone
What is the arrow pointing to?
Occipital Condyle
Where the skull attaches to C1
What is the arrow pointing to?
Vomer

Superior Nuchal line
Where muscle attaches to
What is the arrow pointing to?
Lamboid Suture
Between parietal and occipital
What is the arrow pointing to?
Sutural bone
Technically apart of occipital bone
What is the arrow pointing to?
Temporal Squama
What is the arrow pointing to?
Squamous Suture
Between temporal and parietal bone
What is the arrow pointing to?
Sphenoid Bone
From the sagittal view we see how far reaching it is
What is the arrow pointing to?
Coronal Suture
What is the arrow pointing to?
Zygomatic Arch
What is the arrow pointing to?
Sphenoid Bone
What is the arrow pointing to?
Foramen Magnum
How the spinal cord exits the skull
What is the arrow pointing to?
Zygomatic Bone
Sits anterior to the temporal bone and forms the arch with the temporal bone
What is the arrow pointing to?
Maxilla
You can see the upper teeth from the inferior view
