Orbicularis oris

Zygomaticus

Temporalis

Masseter

Buccinator

Sternocleidomastoid

Orbicularis Oculi

closes eye; produces winking, blinking, squinting ("blink" muscle)

Orbicularis oris

Closes and protrudes lips; used in whistling and forming many letters during speech; the "kissing muscle"

Zygomaticus

elevates corner of mouth; "smiling" muscle

Buccinator

compresses cheek as in blowing sucking whistling; holds food between teeth during chewing

Platysma

Draws down the lower lip and angles of the mouth; tenses skin of the neck; helps depress mandible

Masseter

chewing muscle; closes mouth

Temporalis

closes jaw, elevates and retracts mandible

Sternocleidomastoid

flexes neck; rotates head

Olfactory nerve-

I- smell

optic nerve

II- Vision (adjusts lens and constricting the PUPIL)

Oculomotor

III- movement of eyeball, elevation of upper eyelid, constricting the IRIS, Focus of lens

Trochlear

IV- eye movement (down & out)

Trigeminal

V- chewing, conveys general senses from tongue (not taste), cornea, nasal cavity, front of scalp, upper eyelids.

Abducens

VI- Abduction of eye (lateral movements)

Facial

VII-Taste, salivation, lacrimation, movement of muscles of facial expression

Vestibulocochlear

VIII- Hearing , equilibrium

Glossopharyngeal

IX- Taste, other sensations of the tongue, secretion of saliva, swallowing

DIFFERENCE FROM V???????

Vagus

X-Swallowing, monitors oxygen & carbon dioxide concentrations in blood, senses blood pressure

Accessory

XI-Voice production (Larynx) muscle sense, movement of head, shoulders

Hypoglossal

XII- Movement of tongue during speech, swallowing, muscle sense

Sciatic nerve

Not one of the 12 but important- It is the longest and widest single nerve in the human body, derived from spinal nerves L4 through S3. Supplies the legs.
