Name The 12 Cranial Nerves Flashcards
What are the 12 cranial nerves?
I. Olfactory Nerve. II. Optic III. Oculomotor IV. Trochlear. V. Trigeminal VI. Abducent. VII. Intermediate. VIII. Vestibulocochlear. IX. Glossopharyngeal. X. Vagus. XI. Accessory. XII. Hypoglossal.
What is the olfactory nerve?
It is a sensory nerve responsible from nose and smell.
What is the optic nerve?
The optic nerve is a sensory nerve responsible for eye sight.
What is the oculomotor?
This is a motor nerve. It is responsible for all eye muscles except those supplied by IV and VI.
What is the trochlear?
It is a motor nerve responsible for eye movement from the superior oblique muscle.
What is the trigeminal?
Is a mixed nerve. The sensory function of the face, sinuses and teeth. The motor function is the jaw muscles.
The Abducent?
It is a motor nerve, responsible for eye movement from the external rectus muscle.
What is Intermediate?
Is a mixed nerve. It’s motor nerve function is for submaxillary and sublingual gland and facial muscles. The sensory function is for the front of the tongue and soft palate.
What is the vestibulocochlear?
This is a sensory nerve responsible for hearing and balance (equilibrium).
What is the glossopharyngeal?
This is a mixed nerve. The motor function deals with swallowing, with pharyngeal musculature. The sensory function is taste and sensation on the back part of the tongue, tonsils and pharynx.
What is the vagus?
Again this is a mixed nerve? The motor function deals with the heart, lungs, bronchi and gastrointestinal tract. The sensory function deals with the heart, lungs, bronchi, trachea, larynx, pharynx, gastrointestinal tract, and external ear!
What is the accessory?
The accessory nerve is a motor nerve responsible for the shoulder muscle.
What is the hypoglossal?
This is a motor nerve responsible for the muscles of the tongue.
