Define the epidural space. Does it exist in normal health? |
Space between the skull and dura mater. Meningeal arteries run between these surfaces. Only a space in pathology. |
|
|
What is the origin of the middle meningeal a. and what cranial foramen does it run through? |
Originates from maxillary a. and runs thru the foramen spinosum |
|
|
Where is the subdural space? What's in it? Does it exist in a healthy person? |
Potential space between dura and arachnoid meninges. Contains bridging veins which drain cerebrum into dural sinuses. Space only in pathology. |
|
|
Compare ruptures in the epidural and subdural spaces. Which one produces a slow bleed? |
Epidural space house arteries - fast bleed. The subdural space houses veins, subdural hematoma is a slow bleed. |
|
|
What is in the subarachnoid space? Does a subarachnoid haemmorhage bleed slow or fast? |
It comtains cwrebral vessels and CSF. A haemmorhage causes fast bleed. |
