Cranial nerves Flashcards
cranial nerve I
olfactory
sense of smell
cranial nerves relay info
directly with brain
sensory nerves
special and general senses
somatic nerves
control of skeletal muscles through motor neurons
parasympathetic nerves
regulation of glands, smooth muscles, and cardiac function
II
optic nerve
sense of vision
III
oculomotor
III motor
eye muscles and upper eyelid
propioception from these muscles
III parasympathetic
sphincter of pupil–causing constriction
and cilliary muscles of eyes–accomodation
IV
trochlear
motor to the superior oblique eye muscle
V
trigeminal
has greatest sensory function of all of the nerves
divided into maxillary, mandibular, ophthalmic
only nerve involved in cutaneous innervation of the head
trigeminal ophthalmic
sensory from scalp, forehead, nose, upper eyelid, cornea
trigeminal maxillary sensory
sensory–upper palate, jaw teeth and gums
nasopharynx, nasal cavity, skin and mucous membrane of cheek,
lower eyelid and upper lip
trigeminal mandibular sensory
sensory–lower teeth, jaw, gums
anterior 2/3 of tongue
skin of cheek, chin, auricle and temporal region
trigeminal mandibular motor
muscles of mastication, throat and middle ear
nerve VI
Abducens
motor to lateral rectus of the eye
Nerve VII
Facial
facial sensory
taste from anterior 2/3s of tongue
some of external ear and palate
facial motor
muscles of facial expression, throat and middle ear
facial parasympathetic
submandibular and sublingual salivary glands
lacrimal glands
glands of the nasal cavity and palate
nerve VIII
vetibuochoclear
hearing and balance
nerve IX
glossopharyngeal
glossopharyngeal sensory
taste from posterior 1/3 of tongue
sensory from pharynx, palatine tonsils and posterior 1/3 of tongue
middle ear, carotid body and carotid sinus
glossopharyngeal motor
pharyngeal muscles
