What is the pterion?

An area of weakness on the skull

What 4 bones intersect to make the pterion?

Frontal, parietal, sphenoid, and temporal bones

What is the significance of the pterion?

It is highly vulnerable to fracture; trauma here can cause a epidural hematoma

What is significant about the mandibular fossa?

It articulates with the mandibular condyle to create the temporal mandibular joint (TMJ)

What does the TMJ do?

Allows for up-and-down, side-to-side, and forward-and-back motions of the jaw

What is significant of the styloid process?

It is the site of a lot of muscle attachments

What is significant of the zygomatic arch?

It is the joining of the zygomatic process, temporal bone, and temporal process of zygomatic bone
