Front 13

Olfactory

Back 13

I. (sensory)

Smelland smell interpretation, ­including peristalsis, salivation, and sexualstimulation

Front 14

Optic

Back 14

II. (sensory)

Vision,including visual acuity and peripheral vision

Front 15

Oculomotor

Back 15

III. (motor)

Extraocular movements (EOMs): Upward, Medial, Downward, Up and inEyelidraising and pupil constriction

Front 16

Trochlear

Back 16

IV. (motor)

EOMs:down and in

Front 17

Trigeminal

Back 17

V. (sensory & motor)

Ophthalmic branch (s): sensation to the cornea, conjunctiva, nasal ­mucosa,forehead, and nose Maxillary branch: sensation to the skin of the cheek and nose,lower eyelid, upper jaw, teeth, oral mucosa Mandibular branch:sensation to the lower jaw and motor function to muscles of mastication

Front 18

Abducens

Back 18

VI. (motor)

EOMs: lateral

Front 19

Facial

Back 19

VII. (sensory & motor)

Taste and sensation for the anterior two thirds of the tongue and soft palate; servesas the primary motor nerve for facial expression

Front 20

Acoustic

Back 20

VIII. (sensory)

Hearing & equilibrium.

Front 21

Glossopharyngeal

Back 21

IX. (sensory & motor)

Pharyngeal muscle elevation for swallowing and speech; parotid gland secretion; general sensory (pain, touch, temperature) function

Front 22

Vagus

Back 22

X. (sensory & motor)

Provides most ­parasympathetic ­innervation to a large region; ­effects includedigestion, ­defecation, slowed heart rate, and reduced ­contraction strength

Front 23

Spinal Accessory

Back 23

XI. (motor)

Swallowing and speaking; innervates the muscles that turn the head and elevates the shoulders(shoulder shrug)

Front 24

Hypoglossal

Back 24

XII. (motor)

Tongue movement

Front 25

Test for CN I

Back 25

Olfactory (s): Ask the client to smell and identify different scents.

Client should be able to identify odor.

Front 26

Test for CN II

Back 26

Optic (S) : Ask patient to read from 14 in. away.

Patient should be able to read with each eye together and separately.

Front 27

Test for CN III

Back 27

Oculomotor (m):

Reaction to light: Approaching from the side, use a penlight and observe the pupil. Both illuminated and nonilluminated pupils should constrict.

Reaction to accommodation: Ask patient to look at near and far object, alternating. Move an object toward's their nose. Pupils constrict when looking at near object, dilate for far; converge when moved towards nose.

Front 28

Test for CN IV

Back 28

Trochlear (m): Penlight 1 ft in front of eyes, move in "H" pattern. Both eyes should move together as necessary.

Front 29

Test for CN V

Back 29

Trigeminal (S, M):

When patient looks up, touch sclera to elicit blink reflex.

With eyes closed, wisp a cotton ball over forehead. (light touch)

Test for deep sensation, use alternating blunt and sharp ends of an object. Determine sensation to warm and cold.

Front 30

Test for CN VI

Back 30

Abducens (m): Penlight in "H" movement. Coordinated lateral eye movement.

Front 31

Test for CN VII

Back 31

Facial (S,M): Ask patient to smile, raise eyebrows, frown, puff cheeks, close eyes tightly. Identify various tastes placed on tip of tongue.

Front 32

Test for CN VIII

Back 32

Acoustic (S): Ticking watch identification in both ears (hearing). Walk across room and access gait (balance).

Front 33

Test for IX

Back 33

Glossopharyngeal (S,M): Say "ah" and have the patient yawn to observe upward movement of the soft palate. Elicit gag reflex. Note ability to swallow.

Front 34

Test for CN X

Back 34

Vagus (S,M): Ask patient to swallow and speak (note hoarseness).

Front 35

Test for CN XI

Back 35

Spinal Accessory (m): Shrug shoulders against resistance. Turn head against resistance.

Front 36

Test for CN XII

Back 36

Hypoglossal (m): Stick out tongue and move from side to side.
