The Cranial Nerves

Front 1

______ sensory only for vision. These fibers arise from the retina at the optic disk and travel to the optic chiasma where half of them crossover. From there the optic tracts take impulses to the thalamus which relays them to the visual cortex in the occipital lobe and visual reflex center in the midbrain.

Back 1

Optic - II

Front 2

_____ the ______ nerve to the viscera. Its fibers send stimuli to the heart, stomach, intestines, bronchi, and virtually every other parasympathetic effector between the head and the pelvis. The vagus also provides sensory input for cardiac and respiration. But the muscles of respiration are voluntary and respiration itself is NOT an autonomic function.

Back 2

Vagas - X

parasympathetic

Front 3

_____ sometimes called the 'great sensory nerve of the face' this is the largest of the cranial nerves. It has three branches, the ____ , ____, and ____. From these it receives sensations of a conscious nature, and controls the muscles for chewing.

Back 3

Trigeminal- V

ophthalmic

maxillary

mandibular

Front 4

_____ motor to the muscles for swallowing and _____ to the parotid gland. Sensory from taste buds on the posterior tongue and other areas, as well as other conscious sensations. It is also important in the sensory pathways for control of blood pressure and respiration.

Back 4

Glossopharyngeal - IX

parasympathetic

Front 5

_____ the chief motor nerve of the face, to muscles of facial expression, and ______ to lacrimal and salivary glands. Sensory for taste from from the anterior two-thirds of tongue.

Back 5

Facial- VII

parasympathetic

Front 6

______ motor to the extrinsic and intrinsic eye muscles (except superior oblique and lateral rectus). Its ______ fibers control muscles of the iris (for constricting the pupil) and the ciliary disk, for accommodation of the lens for near vision.

Back 6

Oculomotor - III

parasympathetic

Front 7

______ its name says what this nerve effects - abduction of the eye. It controls the lateral rectus muscle.

Back 7

Abducens - VI

Front 8

_____ sensory nerves for smell. These nerves arise in the olfactory receptors of the nasal epithelium and pass through holes in the cribriform plate to reach the olfactory bulb on the ventral brain surface. The olfactory tracts lead from these bulbs back to the thalamus and then to the frontal lobe for smell perception.

Back 8

Olfactory - I

Front 9

_____ runs together with spinal nerves to the sternocleidomastoid and tapezius muscles.

Back 9

Spinal accessory - XI

Front 10

_____ motor to the muscles of swallowing.

Back 10

Hypoglossal - XII

Front 11

On Old Olympus Towering Tops A Finn And German Viewed Some Hops.

Back 11

I-Olfactory, II-Optic, III-Oculomotor, IV-Trochlear, V-Trigeminal, VI-Abducens, VII-Facial, VIII-Acustic, IX-Glossopharyngeal, X-Vagus, XI-Spinal accessory, XII-Hypoglossal

Front 12

_____ this the nerve bringing stimuli from the inner ear for perception of hearing and balance.

Back 12

Acoustic or Auditory or statoacoustic or vestibulocochlear - VIII

Front 13

_____ controls the _____ of the eye. Called the trochlear because the tendon of this muscles passes through a pulley-shaped process called a trochlea.

Back 13

Trochlear - IV

superior oblique muscle
