8. I put true. By temporals fascia do you mean the deep fascia covering the temporals muscle? I don't think that is the same as the epicranial aponeurosis.

17. This one is tricky for me. I ended up putting true. I was thinking that the great auricular nerve of the cervical plexus supplies the inferior ear lobe and is really close to the ariculotemporal nerve of trigeminal (V3), and that maybe these would over lap. Not sure though.

19. I had a hard time with this one. I put True. My logic was that I would close my eye tightly (orbital part of obicularis oculi) before I would worry about blinking (palpebral part of obicularis oculi) if an object was quickly approaching my eye.

21. I think its true. There is decreased secretion of the lacrimal gland because the GVE parasympathetic fibers of the facial nerve. The paralysis of the orbicularis oculi is because of the zygomatic branches of the facial nerve (SVE).

25 &46. I put false. I put that an epidural hematoma would accumulate blood between the cranial bone proper and the periosteal layer of the dura mater. I can't find any sources that use the word "endosteal"layer. ??

29. The inferior temporal line is a site of attachment for the epicranial aponeurosis. FALSE, superior temporal line.

41. I put true. I thought the epicranial aponeurosis attaches to the superior temporal line, and thus ending the loose areolar space of the scalp.

42. I need help on this one. The epicranial aponeurosis is an attachment sight for the frontal belly of the occipitofrontalis muscle. Therefore the loose areolar space would continue deep to the frontal belly. The frontal belly inserts on the skin and subcutaneous tissue of the eyebrows and forehead. It would end at the obicularis oculi muscle which has a close relationship to the superciliary ridge (but also does not attach there)???

43. I put true for this one. The epicranial aponeurosis attaches to the occipitals muscle at the superior nuchal line, thus ending the loose areolar space.
