Question 26

How do the lateral ventricles communiate with the 3rd ventricle?

Answer 26

Interventricular Foramen (foramen of Monro)

Question 27

What are the 3 layers of the meninges

Answer 27

Dura Mater: tough mother; outer membrane Arachnoid- CSF flows int he subarachnoid space Pia Mater-in contact with brain

Question 28

Arachnoid Granulations

Answer 28

Site of absorption of CSF into systemic circulation -protrude into superior sagittal sinus (a dural sinus)

Question 29

Epidural Hematoma

Answer 29

ruptured meningeal artery in the Epidural Space - located between dura and skull - arteries run in periosteal layer of the dura

Question 30

Subdural Hematoma

Answer 30

Rupture of a vein (typically cerebral vein) into dural sinus forming subdural space -Subdural space=near the junction between dura and arachnoid

Question 31

Aneurysms

Answer 31

True Aneurism 1) Sacular-occurs where arteries branch; can be problematic; will rupture 2) Fusiform-rarely rupture; not problem Symptoms- if its pressing against cranial nerve or not 3) False/pseudoaneuisms - occur in large vessels;doesn't involve all layers of vessel
