: Lecture 62: Parotid Region, Scalp, Facial Nerve, Temporal Fossa (Duplicated from Lecture 61) : True False Questions (J. Radler) : 1. The following muscles contribute to elevation of the upper lip (as during a smile): levator labii superioris, zygomaticus minor, orbicularis oris. : 2. The frontal belly of occipitofrontalis muscle is innervated by both the ipsilateral and contralateral motor nuclei of CN VII. : 3. The auriculotemporal nerve, a branch of the ophthalmic division of the trigeminal nerve (V1), innervates the scalp superior and anterior to the ear. : 4. The angular artery (a distribution from the external carotid artery) forms an anastamosis with the dorsal nasal artery (a distribution from the internal carotid artery). : True False Questions (Dr. Evey) : 1. The zygomatic bone contributes to the zygomatic process. : 2. The temporal process of the facial bone contributes to the zygomatic process. : 3. The mastoid process, middle ear, styloid process, sphenoid spine, and foramen ovale are all parts of the temporal bone. : 4. The inferior temporal line marks attachment of the epicranial aponeurosis. : 5. The coronal suture is between the parietal bone and the occipital bone : 6. The pterion marks the internal location of the anterior branch of the middle meningeal artery. : 7. The lambdoid suture is between the occipital bone and the parietal bone. : 8. The superior temporal line is a site of attachment for the epicranial aponeurosis. : 9. The sagittal suture is between the parietal bones. : 10. The anterior extent of the the sagittal suture is at bregma. : 11. The parietal foramina provide a potential route for infections of the scalp to become intracranial. : 12. The supraorbital nerve extends posteriorly to overlap with the distribution of the greater occipital nerve. : 13. The external nasal nerve is from the ophthalmic division of the trigeminal nerve. : 14. The infraorbital nerve is from the ophthalmic division of the trigeminal nerve. : 15. The cutaneous distribution of the mandibular division of the trigeminal nerve extends from the scalp to the mental process. : 16. The mental nerve enters the face by way of the mental foramen. : 17. The cutaneous distribution of the cervical plexus overlaps with the cutaneous distribution of the mandibular division of the trigeminal nerve. : 18. The parotid duct crosses the lateral surface of the masseter muscle at a location inferior to the transverse facial artery. : 19. A base ball quickly approaching the orbit is apt to activate orbital part of obicularis oculi more so than the palpebral part of obicularis oculi. : 20. The buccal branch of the facial nerve nerve of supplies motor fibers (SVE) to the buccinator muscle and the buccal nerve supplies sensory fibers (GSA) to the oral mucosa of the buccinator muscle. : 21. Perturbation of the facial nerve proximal to the branching of the greater superficial nerve causes dry eye due directly by decreased secretion of the lacrimal gland and indirectly due to by paralysis of the orbicularis oculi. : 22. Dural cranial sinuses communicate extracranially by way of emissary veins. : 23. Parietal emissary veins extend into the loose areolar connective tissue (danger space) of the scalp. : 24. A laceration of the scalp that penetrates the epicranial aponeurosis may introduce infection into the loose areolar tissue space. : 25. An epidural hematoma accumulates blood between the cranial bone proper and the endosteal layer of dura mater. : 26. A subdural hematoma accumulates blood between the meningeal layer of the dura mater and the arachnoid mater. : 27. Bregma marks the intersection of the coronal and sagittal sutures. : 28. Lambda marks the intersection of the lambdoid and sagittal sutures. : 29. The inferior temporal line is a site of attachment for the epicranial aponeurosis. : 30. The distribution of the supratrochlear nerve is medial to the distribution of the supraorbital nerve. : 31. The distribution of the external nasal nerve accounts for the representation of the ophthalmic division of the trigeminal nerve that extends to include the bridge of the nose. : 32. The zygomaticotemporal and zygomaticofacial nerves pass through the orbit and are derived from the maxillary division of the trigeminal nerve. : 33. The buccal nerve, derived from the mandibular division of the trigeminal nerve, provides SVE fibers to the buccinator muscle. : 34. The parotid duct pierces the buccinator muscle adjacent to the lower second molar. : 35. The buccal branch of the facial nerve passes the deep surface of the masseter muscle and the buccal nerve passes the superficial surface of this muscle. : 36. The cervical branch of the facial nerve is the primary source of motor innervation to the platysma muscle. : 37. The external carotid artery is located anterior to the internal carotid artery. : 38. The temporalis muscle is attached at the inferior temporal line. : 39. The facial artery crosses the mandible at the posterior free edge of the masseter muscle. : 40. The "danger" space of the scalp is the loose areolar space. : 41. The superior temporal lines define the lateral extent of the loose areolar space of the scalp. : 42. The superciliary ridges define the anterior extent of the loose areolar space of the scalp. : 43. The superior nuchal line defines the posterior extent of the loose areolar space of the scalp. : 44. Parietal emissary veins communicate between the loose areolar space of the scalp and the intracranial dural sinuses. : 45. The pterion marks the location of the anterior branch of the middle meningeal artery. : 46. Epidural hematomas accumulate between bone proper and the endosteal layer of dura mater. : 47. A scalp laceration that penetrates the epicranial aponeurosis may introduce an intracranial infection
