Temporal Fossa, Temporomandibular Joint, and Infratemporal Fossa - True/False

Comments:
: 1. The lesser superficial petrosal nerve is part of a somatic plexus whereas the buccal nerve is part of an autonomic trunk. : FALSE : 2. tHE MASSETERIC NERVE PASSES THROUGH THE MANDIBULAR NOTCH. : TRUE. : 3. The posterior superior alveolar nerve branches from the maxillary nerve within the pterygopalantine fossa and enters the infratemporal fossa through the pterygomaxillary fissure. : TRUE : 4. The buccal nerve passes the lateral aspect of the masseter muscle. : TRUE : 5. The chorda tympani joins onto the inferior alveolar nerve before distributing to the anterior 2/3 of the tongue. : FALSE - lingual nerve. : 6. Postganglionic fibers from the otic ganglion joins onto, first the chorda tympani, and then the lingual nerve. : FALSE - joins auriculotemporal : 7. A lesion of the lingual nerve within the infratemporal fossa is expected to decrease sensitivity of touch to the posterior 1/3 of the tongue as well as decrease lacrimation. : FALSE. - to anterior 2/3 of tongue : 8. A lesion of the lingual nerve within the floor of the mouth is expected to disrupt both taste and touch to the anterior 2/3 of the tongue. : TRUE : 9. The mouth is apt to be stuck open if the condyle of the mandible slips forward to teh articular tubercle. : TRUE : 10. The left body of the mandible is one of the most commonly broken bones in males. : TRUE : 11. The inferior alveolar nerve contributes to the inferior dental plexus and then continues onto thte face as the mental nerve. : TRUE : 12. The nerve to the mylohyoid conveys GSE fibers to the mylohyoid muscle and SVE fibers to the anterior belly of the digastric. : FALSE - SVE to both muscles : 13. The buccal nerve conveys SVE and GSA fibers to the buccinator muscle. : FALSE - just GSA : 14. The inferior alveolar nerve encircles the middle meningeal artery. : FALSE - auriculotemporal N. : 15. The posterior superior alveolar artery does not enter the pterygopalantine fossa despite that the nerve of the same name is wihtin this fossa. : FALSE - nerve is in this fossa : 16. The medial pterygoid muscle arises from the medial pterygoid plate wheras the lateral pterygoid muscle arises from the lateral pterygoid plate. : FALSE - lateral pterygoid plate : 17. The hamulus is an inferior extension of the lateral pterygoid plate. : FALSE - medial plate : 18. The maxillary artery passes from the infratemporal fossa to the pterygopalantine fossa wheras the maxillary nerve does not enter the infratemporal fossa. : FALSE - nerve enters the pterygopalantine fossa, which is within the infratemporal fossa? : 19. The lingula of the mandible is a site of attachment for the pterygomandibular raphe. : FALSE - attachments are hamulus of sphenoid bone and mylohyoid line : 20. The hamulus of the medial pterygoid plate is a site fo attachment for the sphenomandibular ligament. : FALSE - lingula of mandible and spinous angulis of sphenoid bone : 21. The groove for teh mylohyoid nerve proceeds inferior and anterior from the mandibular foramen. : TRUE : 22. A lesion of the lesser superficial petrosal nerve is expected to cause ipsilateral salivtory deficits. : TRUE? supplies parasympathetic innervation to the parotid gland : 23. A lesion of the lingual nerve at the foramen ovale is expected to disrupt touch (GSA) but not taste (SVA) to the anterior 2/3 fo the tongue. : TRUE : 24. A lesion of the auriculotemporal nerve just medial to the neck of the mandible is expected to cause a salivatory deficit. : TRUE : 25. The sympathetic root of the otic ganglion is derived from the external carotid plexus (middle meningeal plexus). : TRUE
