Function of Optic Nerve (II)

vision

Function of Oculomotor Nerve (III)

eye movement

Function of Trochlear Nerve (IV)

eye movement

Function of Trigeminal Nerve (V)

touch, general sensation to skin, oral cavity, nasal cavity, and more

Function of Abducens Nerve (VI)

eye movement

Function of Facial Nerve (VII)

muscles of facial expression and a buncha other shit

Function of Vestibulo-Cochlear (VIII)

hearing and balance

Function of Glossophayngeal (IX)

sensory to pharynx and more

Function of Vagus (X)

Larynx, pharynx, and rest of body (courses inferiorly to the body)

Function of Accessory Nerve (XI)

sternocleidomastoid and trapezius muscles

Function of Hypoglossal Nerve (XII)

muscles of the tongue

Divisions of the Trigeminal Nerve

V1 - Opthalmic Division V2 - Maxillary Division V3 - Mandibular Division

The paper clip against the forehead is a clinical test of which cranial nerve and specific branch nerve?

Cranial Nerve V and specifically the supraorbital nerve

Function of orbicularis oculi

close the eye

Location of palpebral part of orbicularis oculi and its function

It's in the eyelid and simply closes the eyelid

Location of orbital part of orbicularis oculi and its function

It's on the face and it buries the eyelids (think like in a sandstorm)

What can be damaged (and why) if the orbicularis oculi muscle is paralyzed?

Cornea of eye can be damaged because you cannot spread tears

How is corneal damage prevented in newborns

they sometimes sew the eyelid shut (put a patch on if less severe)

Surrounds and closes the mouth

orbicularis oris

Lateral to bridge of nose; compresses nasal cartilage

compressor nares muscle

Lateral to nostrils; dilates them

dilator nares muscle

Winkles skin of the nose

procerus muscle

Muscle that lifts upper lip

levator labii superioris muscle

Raise and pull upper lip laterally

zygomaticus major and minor muscles

Muscle which raises corner of the mouth

levator anguli oris

Muscle producing a "smile"

Risorius

Muscle associated with frowning

Depressor anguli oris

Muscles depressing the lower lip

Depressor labii inferioris

Muscle wrinkling the skin of the chin

mentalis muscle

Compresses mouth and keeps food between teeth when chewing

buccinator

Muscle forming the wall of the mouth

buccinator

Muscle in the scalp attached to epicranial aponeurosis; raises eyebrows (used in clinical test of facial nerve)

frontalis muscle

Extends from mandible to fascia over pectoralis major; tenses to move the skin of the neck

platysma muscle

Five terminal branches of the facial nerve (VII)

1) temporal 2) zygomatic 3) buccal 4) mandibular 5) cervical

Cause of cheiloschisis (cleft lip)

failure of fusion of medial nasal process and maxillary process

Obstructed Duct (and what to do about it)

Failure of duct to canalize; opened surgically for tears to drain to nasal cavity
