(aka cheekbone)
Makes up mandible

Sutures of skull
- Coronal: transverse, separates frontal and parietal bone
- Sagittal: b/w two parietal bones on top of head
- Lambdoid: back of skull, connects parietal bones w/ occipital bone
- Squamous: connects temporal and parietal bones bilaterally
Foramen ovale
Oval shaped opening, placed obliquely in base of skull in sphenoid bone
Superior orbital fissure
Between the lesser and greater wings of the sphenoid bone
Notches in mandible
- Coronoid notch: anterior to coronoid process
- Mandibular notch: b/w condylar process and coronoid process
TMJ articulation
Between the mandibular fossa and articular tubercle of the temporal bone, and the condylar process of the mandible
Makes up temporal bone
- Carotid canal
- Zygomatic process
- External acoustic/auditory meatus
- Mastoid process
- Stylomastoid foramen (posterior to styloid process)
- Tragus = temporal
