Vagus nerve leaves the skull by 🧡** - the lateral part of jugular foramen - medial part of jugular foramen - upper part of internal acoustic meatus - lower part of internal acoustic meatus - foramen magnum Lateral part of jugular foramen **22. Hypoglossal nerve 🧡** - innervates motorically all muscles of the tongue (except palatoglossus muscle) - carries the general sensory innervation from the superior surface of the tongue - leaves the skull through the lateral part of the jugular foramen - is composed of cranial and spinal roots - innervates motorically only intrinsic muscles of the tongue and sensory last third of the tongue Innervates mororically all muscles of the tongue (except palatoglossus muscle) **23. The infraorbital nerve 🧡** - goes by superior orbital fissure - goes by inferior orbital fissure - goes by foramen ovale - supplies superior lip - supplies superior eyelid 2 & 5 supplies superior lip Travels to Infra = inferior orbital fissure **24. The pterygopalatine ganglion 🧡** - lies under foramen ovale - lies on the lateral side of the optic nerve - receives the parasympathetic fibers from the greater petrosal nerve - sympathetic root is from the plexus of the external carotid artery - receives the sensory branch from the mandibular nerve 3 **25. Choose the correct secretory pathway for the lacrimal gland 🧡** - superior salivatory nucleus -- chorda tympani -pterygopalatine ganglion-zygomatic m lacrimal n. - inferior salivatory nucleus- greater petrosal n. -- pterygopalatine ganglion -- zygomatic nerve -- lacrimal nerve - inferior salivatory nucleus- lesser petrosal nerve -ciliary ganglion -- zygomatic nerve -- lacrimal nerve - superior salivatory nucleus -- greater petrosal nerve -- pterygopalatine ganglion -- zgomatic nerve -- lacrimal nerve - inferior salivatory nucleus -- deep petrosal nerve -- ciliary ganglion -- zygomatic nerve -- lacrimal nerve 1. superior, greater, pterygopalatine **26. Which is the branch of the mandibular nerve 🧡** - hypoglossal nerve - superipr alveolar nerve - lingual nerve - ophthalmic nerve - lacrimal nerve lingual nerve lingula = mandible **27. What is true about the teeth 🧡** - incisor has two roots in maxilla - premolar has two roots in milky dentition - molar in the mandible has three roots - third molar is absent in the milky dentition - premolars have three roots in maxilla 4. third molar Visdomstenner kommer ikke før senere **28. Which papillae of the tongueform V- row in front of sulcus terminalis 🧡** - filiform - fungiform - foliate - vallate - fimbriae vallate papillae v-row = vallate **29. Which muscle DOESNT belong to the tongue 🧡** - superior longitudinal muscle - genioglossus muscle - styloglossus muscle - mylohyoid muscle - hyoglossus muscle Mylohoid muscle Mylohyoid line = mandible NOT tongue **30.
