32
Q

what does the external jugular vein drain?

A

external structures eg posterior auricular vein and retro-mandibular vein

33
Q

what are the cavernous sinuses?

A

drain the blood from the orbits through the ophthalmic veins and from the anterior part of the base of the brain by the sphenoparietal sinus and the middle cerebral veins

34
Q

danger triangle

A

from the bridge of the nose down to the corners of the mouth- risk of surface infection travelling to the brain

35
Q

what is the function of venous sinuses?

A

drain oxygen-depleated blood from the brain

36
Q

what does the emissary veins do?

A

connect the veins outside the cranium to the venous sinuses inside the cranium. They drain from the scalp, through the skull, into the larger meningeal veins and dural venous sinuses

37
Q

what does the emissary veins do?

A

connect the veins outside the cranium to the venous sinuses inside the cranium. They drain from the scalp, through the skull, into the larger meningeal veins and dural venous sinuses

38
Q

what is the risk involved with the emissary vein?

A

infection travelling straight from scalp into brain

39
Q

what direction does the brain drain?

A

towards the back

40

what nerves are most commonly anaesthetised?

A

maxillary and mandibular

41
Q

what bones are part of the temporomandibular joint?

protect the joints

Q

what is the mandibular condyle?

A

the process on the mandible that articulates with the disk of the TMJ

50
Q

what is the mandibular fossa?

A

an oval depression behind the anterior root of the zygomatic process of temporal bone for the reception of the condyle of the mandible
