1

bones of neurocranium

- frontal
- ethmoid
- sphenoid
- occipital
- temporal
- parietal

2

bones of viscerocranium (face)

- mandible
- vomer
- maxilla
- zygomatic
- palatine
- nasal
- lacrimal

3

lambda

- lambdoid and sagittal

4

bregma

- coronal and sagittal

5

pterion

- sphenoid, parietal, frontal and temporal

6

nasion

- frontonasal and internasal

7

asterion

- parietomastoid, occipitomastoid and lambdoid

8

parotid gland: location

- anterior to auricle

9

parotid duct: route

- travels across surface of masseter m
- travels through ducal fat and buccinator m
- enters the oral cavity near upper 2nd molar

10

TMJ blood supply

- deep auricular a

11

TMJ type of joint

- modified hinge synovial joint with articular disc

12

Parts of TMJ

- superior articular cavity
- inferior articular cavity

13

superior articular cavity of TMJ (articulation and movement)

- mandibular fossa and articular tubercle of temporal bone
- articular disc
- gliding/ protrusion/ retrusion

14

inferior articular cavity of TMJ (articulation and movement)

- articular disc
- head of condyloid process of mandible
- hinge movements: elevation/depression
- rotational movements: lateral deviation

15

movements of TMJ

- mouth closed: head of condyloid process located inferior to the mandibular fossa
- to open mouth widely: head of condyloid process moves anteriorly and is then located inferior to the articular tubercle
- if the head of the condyloid process moves anterior to the articular tubercle, can't close mouth
