Posterior auricular

Two Zebras Bit My Cat Posteriorly

Question 2

branches of V1

Answer 2

all somatic sensory

Supra orbital
Supra trochlear
Infra trochlear
External nasal
Lacrimal

1) nasociliary n
2) frontal n
- –supraorbital, infratrochlear, supratrochlear
- Anterior ethmoidal n
- –external nasal n
3) Lacrimal n

Question 3

branches of V2

Answer 3

Zygomatic
–zygomaticotemporal
–zygomaticofacial
Infraorbital

Question 4

branches of V3

Answer 4

Auriculotemporal
Buccal
Lingual
Inferior alveolar
-mental

Question 5

arteries of the face: branches from internal carotid

Answer 5

ophthalmic a

Question 6

arteries of the face: branches from external carotid

Answer 6

Facial

• inferior labial a
• superior labial a
• lateral nasal a
• infraorbital a
• angular a
• supraorbital a
• supratrochlear a

Superficial Temporal
-transverse facial a

Maxillary

Question 7

important neurovascular bundle anterior to ear

Answer 7

superficial temporal a/v

auriculotemporal n

Question 8

3 “Y” veins of the face

Answer 8

1) maxillary + superficial temporal –> retromandibular
2) anterior division of retromandibular –> facial (–> external jugular v)
3) post. div. of retromandibular + post. auricular –> external jugular v)

retromandibular can either drain into the internal jugular (via ant. div.) or into the external jugular (via post. div.)

major structures within the parotid gland

Answer 9

• external carotid a
• retromadibular v
• terminal motor branches of CN VII
• auriculotemporal nerve branches (V3)

nerves exiting nerve point

Answer 10

1) great auricular
2) lesser occipital
3) transverse cervical
4) supraclavicular (lateral, intermediate, medial)
