Cranial Nerves: Cranial nerves are numbered from I to XII. To remember them, the use of mnemonics (learning techniques) is implemented. That is, the first letter of each word in the sentence is the same as the first letter of the cranial nerve.
For example: “On Old Olympus Towering Tops A Finn Viewed Germans Vaulting And Hopping”. Other such sentences are common in the development of a workable technique to aid in remembering the order.
Olfactory I: a sensory nerve responsible for the sense of smell.
Optic II: a sensory nerve responsible for the sense of sight.
Oculomotor III: a mixed nerve, but mostly motor, responsible for the movement of the eyeball, raising the eyelid, and the change in pupil size.
Trochlear IV: a mixed nerve, but mostly motor, responsible for the movement of the eyeball.
Trigeminal V: a mixed nerve responsible for the chewing of food and sensations in the face, scalp, and teeth and the contraction of chewing muscles.
Abducens VI: a mixed nerve, but mostly motor, responsible for the movement of the eyeball.
Facial VII: a mixed nerve responsible for facial expressions, taste, and the secretion of saliva and tears.
Vestibulocochlear (Acoustic) VIII: a sensory nerve responsible for the sense of hearing and balance.
Glossopharyngeal IX: a mixed nerve responsible for swallowing (contraction of pharynx), taste, secretion of saliva, and for the reflex regulation of blood pressure, cardiac, and respiratory reflexes.
Vagus X: a mixed nerve responsible for visceral muscle movement and sensations and for the reflex regulation of blood pressure.
Accessory XI: a mixed nerve, but mostly motor, responsible for swallowing, speaking, and for head and shoulder movement.
Hypoglossal XII: a mixed nerve, but mostly motor, responsible for speech and swallowing (tongue movement).
