The two parietal bones are joined by the

A

sagittal suture

40
Q

interlocking joints of the skull

A

squamous part

48
Q

The - part of the temporal bone has the prominent external auditory canal (external acoustic meatus)

A

tympanic part

49
Q

The __ part of the temporal bone extends inward toward the center of the skull.

A

petrous part

50
Q

3 parts under the squamous part of the temporal bone

A

✓ Zygomatic Process
✓ Zygomatic Arch
✓ Mandibular fossa + Condylar Process
(mandible) = Temporomandibular Joint

51
Q
