Olfactory Nerve 1 |
A sensory nerve functioning in the sense of smell. Originates in the olfactory epithelium of the nasal cavity and terminates in the olfactory lobe. |
|
|
Optic Nerve 2 |
A sensory nerve involved in vision. Originates in the retina and goes to the optic chiasma. The right nerve goes to the left hemisphere and the left nerve goes to the right hemisphere. |
|
|
Oculomotor 3 |
Sensory function is to provide information on the position of the eye. Moto functions include eye and eye lid movement, controlling pupil diameter, and focusing. A mixed nerve originating in the brain and terminating at the eye. |
|
|
Trochlear Nerve 4 |
Sensory function is to provide information on the position of the eye. Motor functions are lateral and inferior movement of the eye. A mixed nerve which originates in the brain and terminates in the eye. |
|
|
Trigeminal Nerve 5 |
Sensory function is to transport information from various touch receptors on the face. Motor function is chewing. A mixed nerve dividing into three branches. The branches originate in the face, jaws, mouth, tongue, and scalp and terminate in the pons. |
|
|
Abductens Nerve 6 |
Sensory function is to provide information on the position of the eye. Motor function is the lateral movement of the eye. A mixed nerve originating in the pons and innervating the lateral rectus eye muscles. |
|
|
Facial Nerve 7 |
Sensory functions are reception of fast stimuli from the anterior 2/3s of the tongue and the position of the face and scalp muscles. Motor functions include controlling facial expressions and secretions from the salivary glands. A mixed nerve originating in the pons. It innervates the muscles of the face, scalp, neck, and salivary glands. |
|
|
Vestibulocochlear 8 |
Sensory nerve functioning in hearing and equilibrium. Motor functions include a response by the head and neck to change in equilibrium. A mixed nerve originating in the inner ear and terminating in the thalamus. |
|
|
Glossopharyngeal Nerve 9 |
Sensory functions are taste and touch by the tongue, the gag reflex, regulation of blood pressure, and respiration. Motor functions include the control of pharyngeal muscles in swallowing, speech, salivation, and gag reflex. A mixed nerve with motor fibers originating in the medulla, and traveling to the pharyngeal region. |
|
|
Vagus 10 |
Sensory functions involve sensations from the respiratory tract, pharyngeal region, external ear canal, and of hunger and fullness. Motor functions include controlling swallowing, coughing, speech and smooth muscles of the respiratory and digestive systems. A mixed nerve with motor fibers originating in the medulla and terminating in the pharyngeal region, digestive, respiratory, and cardiovascular systems. |
|
|
Accessory Nerve 11 |
Sensory function is to provide information on the position of the muscles of the head, neck, and shoulders. Motor function include controlling those muscles and voluntary swallowing. A mixed nerve originating in the medulla and the upper cervical portions of the spinal cord. |
|
|
Hypoglossal Nerve 12 |
Sensory function is to provide information on tongue movement. Motor function is to control muscles involved in food manipulation, swallowing, and speech. Primarily a motor nerve originating in the upper cervical portions of the spinal cord and terminating in the muscles of the tongue. |
