Epidural hemorrhage/ hematoma

Laceration/ tearing of the meningeal artery and

Bleeding into the potential space between the cranium and periosteal layer of dura

34

the periosteal dura encloses the

meningeal vessels.

35

subdural space

Potential space between the dura and arachnoid

36

Subdural Hemorrhage/ Hematoma

secondary to rapid acceleration/deceleration which pulls the brain away from the skull

37

tears cerebral veins as they enter the dural sinus

Subdural Hemorrhage/ Hematoma

38

subarachnoid space

true space that contains blood vessels and CSF

39

Interventricular Foramen (Foramen of Monroe)

communicates Lateral Ventricles (2) Right Left

to 3rd ventricle

40

communication between 3rd and 4th ventricle

Cerebral Aqueduct (Aqueduct of Sylvius)

41

Subarachnoid Hemorrhage/ Hematoma

arterial hemorrhage

42

Subarachnoid Hemorrhage/ Hematoma

~70% are 2° aneurysm

45

Foramen of Magendie

Midline opening in the 4th ventricle

46

Foramen of Luschka

Paired openings in the 4th ventricle

47

CSF is made in the ------ -------, it circulates through the ---------  and exits the ---- ventricle

 CSF is made in the choroid plexus, it circulates through the ventricles and exits the 4th ventricle

48

As CSF leaves the 4th ventricle, it enters the

subarachnoid space.

49

CSF travel to subarachnoid space into the dural venous sinuses

via arachnoid granulations
