Face- Lecture 14 (cont.)

Question 1

Describe the pathway for facial artery. What are the names of the 3 branches that form?

Answer 1

Begins from the branch of the external carotid artery

Winds around the lower mandible and becomes superficial

Passes laterally to the mouth

Forms 3 branches here:

• Superior and inferior Labial arteries
• Lateral nasal artery
• Angular artery

Question 2

What are the other 2 facial arteries?

Answer 2

Superficial Temporal

Transverse Facial

Question 3

Describe the Superficial Temporal arteries pathway.

Answer 3

Terminal branch of the external carotid artery

Emerges between the TMJ and auricle

Enters the temporal fossa

Divides into the frontal and parietal branches

Question 4

Describe the Transverse Facial arteries pathway. What 3 structures does this artery supply?

Answer 4

Arises from the superficial temporal artery

Crosses face superficial to the masseter muscle

Anastomoses with the facial artery

Supplies:
Parotid gland
Masseter muscle
Skin of the face

Question 5

What 4 nerves supply sensory innervation to the face?

Answer 5

Trigeminal nerve (CN V)
Greater occipital
Lesser occipital
Greater auricle

Question 6

What are the 3 branches of the Trigeminal nerve (NC V)?

Answer 6

Ophthalmic (V1)
Maxillary (V2)
Mandibular (V3)

*Test- The V’s are for the foramina through which each of these nerves exits

Question 7

What cranial nerve is responsible for the innervation of the face?

Answer 7

Cranial Nerve 7- Facial nerve is the primary motor nerve to muscles of facial expression

Question 8

Cranial nerve 7 also supplies innervation to muscles derived from what?

Answer 8

Second pharyngeal arch (hyoid arch)

Question 9

What are the 5 branches of cranial nerve 7?

Answer 9

Temporal
Zygomatic
Buccal
Mandibular
Cervical
