: : : 1. The zygomatic bone contributes to the zygomatic process. False. : : 2. The temporal process of the facial bone contributes to the zygomatic process. False- zygomatic bone. : : 3. The mastoid process, middle ear, styloid process, sphenoid spine, and foramen ovale are all parts of the temporal bone. Sphenoid spine and foremen ovale, part of sphenoid bone : : 4. The inferior temporal line marks attachment of the epicranial aponeurosis. False-superior. Boundary for spread of infection. : : 5. The coronal suture is between the parietal bone and the occipital bone. False- lamboid. : : 6. The pterion marks the internal location of the anterior branch of the middle meningeal artery. True. : : 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. True. : : 9. The sagittal suture is between the parietal bones. True : : 10. The anterior extent of the the sagittal suture is at bregma.True- where it emeets coronal? : : 11. The parietal foramina provide a potential route for infections of the scalp to become intracranial. True- via parietal emissary veins. : : 12. The supraorbital nerve extends posteriorly to overlap with the distribution of the greater occipital nerve. True. : : 13. The external nasal nerve is from the ophthalmic division of the trigeminal nerve. True- it has an excellent course. : : 14. The infraorbital nerve is from the ophthalmic division of the trigeminal nerve. False- maxillary. : : 15. The cutaneous distribution of the mandibular division of the trigeminal nerve extends from the scalp to the mental process. True- auriculotemporal to mental : : 16. The mental nerve enters the face by way of the mental foramen. True. : : 17. The cutaneous distribution of the cervical plexus overlaps with the cutaneous distribution of the mandibular division of the trigeminal nerve. True : : 18. The parotid duct crosses the lateral surface of the masseter muscle at a location inferior to the transverse facial artery. True. : : 19. A base ball fastly approaching the orbit is apt to activate orbital part of obicularis oculi more so than the palpebral part of obicularis oculi. False- palpabrae part as it is the blinking reflex? Tight closing is orbital : : 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. True. : : 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. True. : : 22. Dural cranial sinuses communicate extracranially by way of emissary veins. True : : 23. Parietal emissary veins extend into the loose areolar connective tissue (danger space) of the scalp. True : : 24. A laceration of the scalp that penetrates the epicranial aponeurosis may introduce infection into the loose areolar tissue space. True. : : 25. An epidural hematoma accumulates blood between the cranial bone proper and the endosteal layer of dura mater. True. : : 26. A subdural hematoma accumulates blood between the meningeal layer of the dura mater and the arachnoid mater. True.
