all innervated but hypoglossal nerve

Question 1

Cutaneous trigeminal branches

Answer 1

V2 Maxillary: infraorbital, zygomaticofacial, zygomaticotemporal

V3 Mandibular: mental, Buccal, auriclotemporal

Question 2

suprahyoid muscles

Answer 2

anterior belly of digastric (V3), mylohyoid(V3. nerve to..), stylohyoid(facial), geniohyoid (ansa c)

Question 3

middle meningeal artery

Answer 3

branch of maxillary art which is a branch of the external carotid

Question 4

infrahyoid muscles

Answer 4

omohyoid, sternothyroid, sternohyoid–all ansa cervicalis

thyrohyoid, C1

Question 5

stylohyoid

Answer 5

the tendon of the digastric goes through stylohyoid near hyoid bone
facial nerve

Question 6

nerve that goes into the mandible

Answer 6

inferior alveolar nerve. enters through the mandibular foramen

Question 7

2 eye muscles that originate from bone

Answer 7

Levator palpebrae superioris: lesser wing of sphenoidal bone????
Sup oblique:
Inferior Oblique: floor of the orbital bone

Question 8

the 2 eye muscles NOT innervated by oculomotor

Answer 8

Lateral rectus: Abducens (LAR)

Superior Oblique: Trochlear (its ligament that holds it is also trochlear)

Question 9

Anulus Zinn

Answer 9

common tendinous ring: the 4 rectus eye muscles and superior oblique raised from it.
The tendon is attached to the sphenoidal bone

trochlear and ophthalmic do NOT go through
ONLY Oculomotor and Abducens
