hypoglossal nerve Flashcards
what are the muscles that the hypoglossal nerve supply
the intrinsic and extrinsic muscles of the tongue, except for the palatoglossus
what type of information is carried by the hypoglossal nerve
exclusively motor nerve
where is the nerve of the hypoglossal nerve located
floor of the rhomboid fossa
lower motor neurons cell bodies of the hypoglossal nerve receive information from where
both cerebral hemispheres
the hypoglossal nerve emerges as a series of rootlets where
in the sulcus between the pyramid and the olive of the medulla oblongata
the hypoglossal rootlets combine to form a bundle that exists the skull where
hypoglossal canal
the hypoglossal nerve descends forming a loop at which the arch will reach what
the base of the tongue
fibers from the first and second cervical nerves will travel with but not incorporate into the hypoglossal nerve, they will split off to form what
superior root of the ansa cervicalis
some cervical fibers will continue with the hypoglossal nerve to supply what
the geniohyoid and thyrohyoid muscles
the hypoglossal nerve gives off a lingual branch which will supply what
hypoglossus, genioglossus, styloglossus muscles
half of the tongue to atrophy, stick out your tongue and it deviates to the weak side all belong to what diesease?
