16
Q

interconnections: spongy porous bone bw outer and inner cortical layers; usually found within roofing bones

A

Diploe

17
Q

( ) channels travel within Diploe

A

venous

18
Q

interconnection: connect scalp to inside neurocranium

A

emissary veins

19
Q

3 major arteries involved with supply to head

A

1) vertebral artery
2) internal carotid
3) external carotid

20
Q

artery supply: inside neurocranium

A

internal carotid and vertebral with minor contribution from middle meningeal

21
Q

artery supply: outside neurocranium

A

branches of external carotid; superficial temporal and occipital

22
Q

artery supply: outside of face

A

mainly facial branch of external carotid

23
Q

artery supply: inside face

A

maxillary branch of external carotid; opthalamic branch of internal carotid does inside orbit

24
Q

venous drainage: inside neurocranium

A

internal jugular

25
Q

venous drainage: outside face

A

facial vein (usually trans into internal jugular) but system is complex with many interconnections

26
Q

venous drainage: Danger area of face

A

1) facial vein
2) upper lip
3) bridge of nose

27
Q

infection or thrombi from danger area of face can travel to ( ) from facial to opthalmic veins to cavernous sinus

A

cranial cavity

28
Q

veins of the head lack what?

A

valves

29
Q

superficial cervical lymph nodes located where the head meets the neck drain to where?

A

deep cervical lymph nodes, mainly under the SCM

30
Q

provides sensory innervation to face and some motor to head

A

trigeminal nerve (V)

31
Q

trigeminal: supplies oribital regions (forehead and anterior scalp, upper eyelid and dorsum of nose), anterosuperior nasal cavity

A

opthalamic (V1)

32
Q

trigeminal: supplies upper jaw regions (lower eyelid, side of nose, upper lip and upper dentition), posteroinferior nasal cavity

A

Maxillary division (V2)

33
Q

trigeminal: supplies lower jaw region including lower dentition, skin anterior to ear, some sensory to inside oral cavity; motor to muscles of mastication

A

mandibular division (V3)

34
Q

( ) from cervical region provide sensory innervation to rest of head

A

dorsal or ventral primary rami

35
Q

facial nerve controls openings of what 3 cavities of the head?

A

1) eye
2) nasal
3) oral

36
Q

muscle: orbital part tightly closes eye; palpebral part for blinking

A

orbicularis oculi

37
Q

muscle: closes mouth and puckers lips

A

orbicularis oris

38
Q

muscle: compresses cheeks, helps keep food positioned bw occlusal surfaces of teeth for mastication, helps cheeks resist forces generated by blowing and sucking

A

buccinator
