1. The zygomatic bone contributes to the zygomatic process.
- false ⇒ zygomatic process is of temporal bone
2. The temporal process of the facial bone contributes to the zygomatic process.
- false ⇒ no facial bone
3. The mastoid process, middle ear, styloid process, sphenoid spine, and foramen ovale are all parts of the temporal bone.
- false
4. The inferior temporal line marks attachment of the epicranial aponeurosis.
- false ⇒ superior temporal line
5. The coronal suture is between the parietal bone and the occipital bone
- false ⇒ frontal and parietal
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.
- true
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
11. The parietal foramina provide a potential route for infections of the scalp to become intracranial.
- true
12. The supraorbital nerve extends posteriorly to overlap with the distribution of the greater occipital nerve.
- false
13. The external nasal nerve is from the ophthalmic division of the trigeminal nerve.
- true
14. The infraorbital nerve is from the ophthalmic division of the trigeminal nerve.
- false ⇒ infraorbital is from maxillary division
15. The cutaneous distribution of the mandibular division of the trigeminal nerve extends from the scalp to the mental process.
- true
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 baseball quickly approaching the orbit is apt to activate orbital part of obicularis oculi more so than the palpebral part of obicularis oculi.
- true
20. The buccal branch of the facial nerve supplies motor fibers (SVE) to the buccinator muscle and the buccal nerve supplies sensory fibers (GSA) to the oral mucosa of the buccinator muscle.
- false ⇒ have you decided your account on this??
21. Perturbation of the facial nerve proximal to the branching of the greater superficial petrosal 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
27. Bregma marks the intersection of the coronal and sagittal sutures.
- true
28. Lambda marks the intersection of the lambdoid and sagittal sutures.
- true
29. The inferior temporal line is a site of attachment for the epicranial aponeurosis.
- false ⇒ superior
30. The distribution of the supratrochlear nerve is medial to the distribution of the supraorbital nerve.
- true
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.
- true
32. The zygomaticotemporal and zygomaticofacial nerves pass through the orbit and are derived from the maxillary division of the trigeminal nerve.
- true
33. The buccal nerve, derived from the mandibular division of the trigeminal nerve, provides SVE fibers to the buccinator muscle.
- false ⇒ buccal branches of facial
34. The parotid duct pierces the buccinator muscle adjacent to the lower second molar.
- false ⇒ upper 2nd 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.
- false ⇒ buccal n. is deep to masseter
36. The cervical branch of the facial nerve is the primary source of motor innervation to the platysma muscle.
- true
37. The external carotid artery is located anterior to the internal carotid artery.
- true
38. The temporalis muscle is attached at the inferior temporal line.
- true
39. The facial artery crosses the mandible at the posterior free edge of the masseter muscle.
- false ⇒ anterior to masseter

- true
41. The superior temporal lines define the lateral extent of the loose areolar space of the scalp.
- true
42. The superciliary ridges define the anterior extent of the loose areolar space of the scalp.
