cranial nerves

cranial nerve I

cranial nerve that provides a sense of smell

cranial nerve II

the cranial nerve that provides the sense of vision

cranial nerve III

the cranial nerve that innervates the muscles that cause motion of the eyeballs and upper lid.  this nerve also carries parasympathetic nerve fibers that cause constriction of the pupil (sphincter muscle), and accommodation of the lens (ciliary muscle).

cranial nerve IV

this cranial nerve innervates the superior oblique muscle of the eyeball, which allows a downward gaze

cranial nerve V

this cranial nerve supplies sensation to the scalp, forehead, face, and lower jaw via three branches: the ophthalmic, maxillary, and mandibular divisions.  it also provides motor innervation to the muscles of mastication (chewing), the throat, and the inner ear

cranial nerve VI

this cranial nerve supplies that lateral rectus muscle of the eyeball (lateral movement)

cranial nerve VII

this cranial nerve supplies motor activity to all muscles of facial expression, the sense of taste to the anterior two thirds of the tongue, and cutaneous sensation the the external ear, tongue, and palate. it also carries parasympathetic stimulation to the salivary glands, lacrimal gland, and the glands of the nasal cavity and palate.

cranial nerve VIII

this cranial nerve passes through the internal auditory meatus and provides the senses of hearing and balance

cranial nerve IX

this cranial nerve supplies motor fibers to the pharyngeal muscles. it provides taste sensation to the posterior portion of the tongue and carries parasympathetic fibers to the salivary glands (parotid glands) located on each side of the face

cranial nerve X

this cranial nerve provides motor functions to the soft palate, pharynx, and larynx (voice). it also carries sensory fibers from the inferior pharynx, larynx, thoracic, and abdominal organs, taste bud fibers from the posterior tongue, and parasympathetic fibers to thoracic and abdominal organs.

cranial nerve XI

this cranial nerve provides motor innervation to the muscles of the soft palate and the pharynx and to the sternocleidomastoid and trapezius muscles. it also controls swallowing, speech, and head and shoulder movements.

cranial nerve XII

this cranial nerve provides motor function to the muscles of the tongue and throat

Having the patient follow finger with eyes assesses which cranial nerves?

having the patient smile and clench teeth assesses which cranial nerves?

having the patient shrug their shoulders assesses which cranial nerves?

having the patient stick out their tongue assesses which cranial nerves?

having the patient swallow assesses which cranial nerves?

the fact that the patient responds when prompted during the assessment of the other cranial nerves denotes the assessment of which cranial nerve?
