16

What type of joints exists between the parietal and frontal bones? Discuss the joint.

Suture joints (temporomandibular is synovial)
-This joint has a disc inside: makes superior/inferior
compartment.
-Allows depression and elevation of the jaw, you can protrude and retract your jaw, and move it side to side.
-Has sensation from the trigeminal nerve
-trigeminal (CN V) nerve also controls muscles of chewing such as masseter and temporalis
