Q

_______ orbital part originates from the medial part of the medial palpebral ligament, the nasal part of the frontal bone, and the frontal process of the maxilla. The fibers encircles the eye and inserts into the lateral palpebral raphe and frontalis muscle, corrugator muscle, and the tarsi. The palpebral portion also arises from the medial palpebral ligament and lacrimal crest and laterally the fibers of both lid interdigitate at the lateral palpebral raphe. These muscles are responsible for closing the eye.

Q

_______ arises from the posterior and lateral part of the zygomatic bone below the orbicularis oculi and passes obliquely downward and forward to the corner of the mouth where it attaches to skin and mucosa . The zygomaticus minor originates from the zygomatic bone either below or deep to the orbicularis oculi and runs toward the mouth running parallel and above the zygomaticus major to insert into the upper lip just medial to the corner of the mouth.

A

zygomaticus major

19
Q

_____ originates in the lateral cheek from the subcutaneous tissue over the parotid gland. It runs forward and slightly downward across the masseter muscle where it inserts into the skin and mucosa at the lateral corner of the mouth. Known as the smiling muscle it pulls the lips laterally and upward.

A

risorius

20
Q

______ surrounds the mouth so it actually can be considered with the upper and lower mouth group and takes origin from other facial muscles in the maxilla, the nasal septum and the mandible and inserts into the dermis of lips and surrounding muscles. This muscle closes, purses, and protrudes the lips.

A

orbicularis oris

21
Q

______ arises from the anterior portion of oblique line and side of the body of the mandible at the level of the canine, premolar and first molar and converges to the corner of the mouth where it is partly inserted into skin and also the upper part of the orbicularis oris. It has the shape of a broad-based triangle.

A

depressor anguli oris

22
Q

_____ originates from the front of the mandible and passes upward in front of the mental foramen. It takes origin deep to the depressor anguli oris. It is quadrangular in shape and runs medial to the depressor anguli oris.

A

depressor labii inferioris

23
Q

_____ originates from the mandible near the root of the incisor and passes downward to insert into the skin of the chin.

A

mentalis

24
Q

_____ originates in the pectoral and deltoid fascia and inserts on the mandible it is innervated by cervical branches of the Facial Nerve.

A

platysma

25
Q

_____ originates from the pterygomandibular raphe and the alveolar arches and inserts in the dermis of the lips and the surrounding muscles of the mouth. This muscle compresses the cheek and is the most lateral muscle of the cheek.

A

buccinator

26
Q

____ is an important landmark for the dental anesthesia of the mandibular teeth.

A

raphe

27
Q

All of the muscles of facial expression receive motor innervation from the ____ nerve.

A

CN VII

28
Q

What arch are the facial nerve and muscle of facial expression associated with?

A

The 2nd or hyoid pahryngeal arch

29
Q

______ exits the skull from the stylomastoid foramen and typically divides within the parotid gland ultimately giving rise to five major branches that provide regionally appropriate innervation to the facial muscles.

A

The facial nerve

30
Q

What nerve provides motor innervation to all the muscles of facial expression?

A

facial nerve

31
Q

Anterior and superior auricular, frontalis, orbicularis oculi, and corrugator are innervates by what branch of the facial nerve?

A

temporal

32
Q

Orbicularis oculi and corrugator are innervated by what branch of the facial nerve?

A

zygomatic

33
Q

Procerus, nasalis, depressor septi, zygomaticus minor and major, levator labii superioris, levator labii superioris alaque nasi, risorius, orbicularis oris, and buccinator are innervated by what branch of the facial nerve?

A

buccal

34
Q

Risorius, orbicularis oris, mentalis, depressor anguli oris, and depressor labii inferioris are innervated by what branch of the facial nerve?

A

mandibular (marginal)

35
Q

Platysma is innervated by what branch of the facial nerve?

A

cervical

36
Q

The blood supply of the superficial face is provided by branches of the ______.

A

external and internal carotid artery

37
Q

The facial vein has anastomosis with ______ and these drain the blood into the _______ formed by the dura mater at the base of the middle cranial fossa.

A

superior and inferior ophthalmic veins, cavernous sinus

38
Q

Why the danger area of the face termed so?

A

the angular vein from the facial communicates with ophthalmic veins and thereby may let infection from the face into the meningeal sinuses leading to a deadly condition

39
Q

What are the nerves that branch from V1 (ophthalmic) division of the trigeminal nerve?

A
  • supraoribtal nerve
  • supratrochlear nerve
  • palpebral branch of the lacrimal nerve
  • infratrochlear nerve
  • external nasal branch of the anterior ethmoidal
40
Q

What are the nerves that branch from V2 (maxillary) division of the trigeminal nerve?

A
  • infraorbital nerve
  • zygomaticofacial nerve

41
Q

What are the nerves that branch from V3 (mandibular) division of the trigeminal nerve?

A
  • mental nerve
  • buccal nerve
  • auriculotemporal nerve
42
Q

How do you diagnose trigeminal neuralgia?

A

Compress the terminal branches of the trigeminal nerves: supraorbital foramen (V1), infraorbital foramen (V2), and the mental foramen (V3).

43
Q
