Summary of Cranial Nerves :  Anterior of the Brain to Posterior

I. Olfactory:

 Sensory

nerves for smell

Cranial Nerve I:  olfactory nerve

II. Optic:

Sensory

nerve for vision.

Cranial Nerve II Optic Nerve

III. Oculomotor:

Somatic & Parasympathetic:

 control of extrinsic eye muscles and pupil dilation.

 

Cranial Nerve III Oculomotor Nerve

IV. Trochlear:

Somatic

control of muscles that surround the eye.

Cranial Nerve IV:  Trochlear Nerve

V. Trigeminal:

Sensory & Somatic

control of facial nerves and muscles for chewing.

VI. Abducens:

 Somatic

muscle control of lateral movement of the eyeball.

 

Cranial Nerve VI:  Abducens Nerve

VII. Facial:

Sensory, Somatic & Parasympathetic

control over facial expression and taste.

 

Cranial Nerve VII:  Facial Nerve

VIII. Vestibulocochlear or Auditory Nerve:

Sensory

 nerve for hearing.

IX. Glossopharyngeal:

Sensory, Somatic & Parasympathetic

control over taste, the tongue and the pharynx.

 

Crainal Nerve IX:  Glossopharyngeal Nerve

X. Vagus

Primary Parasympathetic

 nerve with some Somatic and Sensory functions. Only cranial nerve that runs to the abdomen and thorax. Controls visceral organs.

 

Cranial Nerve X:  Vagus Nerve

XI. Accessory:

 Somatic

control over larynx, pharynx and sternocleidomastoid muscles
