Foramen spinosum
Foramen magnum
Foramen spinosum

Which is the subarachnoid space?
Where is lumbar puncture performed?
Between T12 & L1
Between L1 & L2
Between L3 & L4
Below L5
Between L3 & L4
The spinal cord ends at the vertebral level L1/2 so lumbar punctures are performed below this level.
Where is the danger triangle of the face? [1]
Explain why this region is called the danger triangle [2]
The angular and ethmoidal veins drain this region of the face into the opthalmic veins which drain into the cavernous sinus.
This provides a potential route of infection from the nasal area to the brain, causing cavernous sinus thrombosis, meningitis or brain abscess.
SAH can lead to which pathology? [1]
Frank blood in the subarachnoid space is irritating and can cause (aseptic) meningitis.
Which of the following is principally caused by movement of the brain, not impact
Epidural
Sub dural
Sub arachnoid
Intracranial
Sub dural
When the head is accelerated, the inertia of the brain causes its movement to lag behind that of the skull. This leads to traction on bridging veins running between brain and dura mater, which get torn.
Which of the following commonly causes damage to axons in the underlying brain
Epidural
Sub dural
Sub arachnoid
Intracranial
Sub dural
Blood from the ruptured vessels spreads freely through the subdural space and can envelop the entire hemisphere. Because of the forces involved in producing a subdural haemorrhage, there is very often damage to axons in the underlying brain as well
