Front 1

Olfactory

Back 1

Location: Olfactory Bulb

Function: Transmits the sense of smell

Hint 1

Front 2

Optic

Back 2

Location: Optic chiasma

Function: Transmits visual information to the brain

Hint 2

Front 3

Occulomotor

Back 3

Location: Midbrain

Function: Innervates the dorsal rectus, medial rectus, ventral rectus, and ventral oblique, which collectively perform most eye movements

Hint 3

Front 4

Trochlear

Back 4

Location: Midbrain (dorsal)

Function: Innervates the superior oblique muscle, which depresses, pulls laterally, and intorts the
eyeball

Hint 4

Front 5

Trigeminal

Back 5

Location: Pons

Function: Receives sensation from the face and innervates the muscles of mastication

Hint 5

Front 6

Abducens

Back 6

Location: Medulla Oblongata

Function: Innervates the lateral rectus, which abducts the eye and the retractor bulbi which forces the third eyelid across the surface of the cornea as a protective mechanism.

Hint 6

Front 7

Facial

Back 7

Location: Medulla Oblongata

Function: Provides motor innervation to the muscles of facial expression and stapedius, receives the special sense of taste from the anterior 2/3 of the tongue, and provides secretomotor innervation to the salivary glands (except parotid) and the lacrimal gland

Hint 7

Front 8

Vestibulocochlear

Back 8

Location: Medulla Oblongata

Function: Senses sound, rotation and gravity (essential for balance & movement)

Hint 8

Front 9

Glossopharyngeal

Back 9

Location: Medulla Oblongata

Function: Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus

Hint 9

Front 10

Vagus

Back 10

Location: Medulla Oblongata

Function: Supplies branchiomotor innervation to most laryngeal and haryngeal muscles; provides
parasympathetic fibers to nearly all thoracic and abdominal viscera down to the splenic flexure; and receives the special sense of taste from the epiglottis

Hint 10

Front 11

Accessory

Back 11

Location: Medulla Oblongata

Function: Controls muscles of the neck and overlaps with functions of the vagus

Hint 11

Front 12

Hypoglossal

Back 12

Location: Medulla Oblongata

Function: Provides motor innervation to the intrinsic muscles of the tongue and other glossal muscles
