Orbicularis oculi 3 parts

Palpebral- gently closes eyelids
Lacrimal - aids in drainage of tears
Orbital part- tightly closes the eyelids

1

Sensory nerve for face and the motor innervation for muscles of mastication

Trigeminal nerve
Cnv3 has some motor fibers

2

Motor nerve of the face

Facial nerve
Mandibular ( cnv3)

3

6 branches of facial nerve

Posterior auricular nerve

Temporal
Zygomatic
Buccal
Marginal mandibular
Cervical

4

Branches of all three divisions of the trigeminal nerve cnv123

5

Posterior to the auricles, innervation of the scalp is by...

Spinal cutaneous nerves c2c3

6

Most arteries supplying the face are branches of the...

External carotid arteries

7

Facial artery provides...

The major arterial supply to face
Branch of the eca
Winds around inferior border of mandible
Crosses over face to median angle of eye

8

Termination of the facial artery...

Angular artery... Supplies the medial angle of the eye

9

Branches of facial artery

Lateral nasal
Superior and inferior labial arteries

10

Superficial temporal artery emerges on face between...

The temporomandibular joint and the auricle...

Ends in the scalp by dividing into frontal and parietal branches

11

What provides the primary superficial venous drainage of face? And where does this vein begin?

Facial vein and begins at the medial angle of the eye as the angular vein.

12

The facial vein drains directly into the...

Internal jugular vein

13

The great auricular nerve provides sensory innervation to...

The parotid sheath, gland, and overlying skin

14

The parasympathetic component of the glossopharyngeal nerve(cn 9) supplies

Secretory fibers to the parotid gland

15

What muscle squints the eye?

Obicularis oculi...orbital part


Palpebral gently closes the eye

16

What muscle milks the parotid duct during mastication and covers the alveolar processes ?

Buccinator

17

The facial nerve enters? Exits?

Enters internal auditory canal
Exits stylomastoid foremen

18

Parotid plexus

Posterior auricular nerve
Temporal n
Zygomatic n
Buccal n
Marginal mandibular n
Cervical n

19

Parotid gland is...

Saliva secretion
Duct empties Between 2nd maxillary molar

Innervation - glossopharyngeal n cn ix

20

Acting unilaterally the medial pterygoid ?

Contralateral deviation of mandible

21

Actions of lateral pterygoid ?

Bilaterally- protracts chin
Unilaterally - contralateral divination

22

Temporomandibular joint

Synovial hinge
Articular disk separates synovial joint capsule in two
Articulation between condyle of mandible and mandibular fossa of temporal bone

23

Protrusion and retrusion at TMJ

Is anterior and posterior translation without rotation

24

Lingual and inferior alveolar are branches of what nerve?
How about chorda tympani?

Trigeminal n
Facial n

25

Maxillary

26

Emissary veins communicate between the...

Veins of face and scalp and the venous dural sinus
No valves

Cavernous sinus- to dural venous structures

27

Nasal cavity spans from?to?

Nares to nasopharynx

28

Nasal cavity lies under what bones?

Sphenoid, ethmoid, frontal, and nasal

Lies above palatine and maxilla bones
