Cranial Nerve VII Flashcards
CN VII supplies motor innervation to
muscles of facial expression and taste at anterior 2/3 of the tongue
movement of CN VII that is controlled with bilateral symmetry
forehead movement
CN VII divides within this area
parotid gland
two divisions of CN VII
temporofacial and cervicofacial
CN VII innervates this muscle in the ear
stapedius muscle
peripheral facial paralysis associated with CN VII is called
prosopoplegia
with Bell’s palsy the lesion is located
peripheral to the geniculate ganglion
causes flaccid paralysis involving all ipsilateral facial muscles
Bell’s palsy
central type of facial paralysis with bilateral innervation and the forehead is spared
stroke
CN VII exits the skull here
stylomastoid foramen
CN VII parasympathetic function
gland function (lacrimal, sublingual, submandibular)
CN VII sensory function
taste
with CN VII, an infranuclear or peripheral lesion causes this
Bell’s palsy
with CN VII, a supranuclear or central lesion causes this
stroke
CN VII travels here
internal auditory meatus
