1Learning point: A good way to remember layers of the cranium is with the acronym SCALP
[blank_start]Skin[blank_end]
[blank_start]Connective Tissue[blank_end]
[blank_start]Aponeurosis[blank_end]
[blank_start]Loose Connective Tissue[blank_end]
[blank_start]Pericranium[blank_end]- ASkin
- BConnective Tissue
- CAponeurosis
- DLoose Connective Tissue
- EPericranium
2The central structure of a eukaryotic neuron responsible for producing rRNA is called the [blank_start]nucleolus[blank_end]
- Anucleolus
3Acute neuronal injury, whereby hypoxia/ischaemia causes irreversible damage to the neuronal cell (loss of nucleolus, etc) is known as ...
- ARed neuron
- BWhite neuron
- CYellow neuron
4The most important histological indicator of CNS injury is [blank_start]gliosis[blank_end].
- Agliosis
5Gliosis is acute [blank_start]hyperplasia[blank_end] and [blank_start]hypertrophy[blank_end] of glial cells (astrocytes, oligodendrocytes, microglia) and is a major indicator of CNS damage.
- Ahyperplasia
- Bhypoplasia
- Chypertrophy
- Datrophy
6Which type of glial cell is typically damaged as part of demyelinating conditions such as multiple sclerosis?
- AOligodendrocytes
- BSchwann cells
- CAstrocytes
- DMicroglia
7The immune mediators of the CNS are called ...
- AMicroglia
- BOligodendrocytes
- CAstrocytes
- DNatural Killer cells
8Are brain infarctions more frequently embolic or thrombotic?
- AEmbolic
- BThrombotic
9Cerebral infarction (due to e.g. thrombosis or emboli) is more prevalent in women than men.
- AVerdadeiro
- BFalso
10Differentiate thrombotic from embolic cerebral infarction:
[blank_start]Thrombotic[blank_end] = Atherosclerotic segment formed in the arteries of the brain
[blank_start]Embolic[blank_end] = Substance formed elsewhere in the body (commonly internal carotid, aortic arch or heart) that travels to the brain in the blood and becomes lodged, thus causing infarction.- AEmbolic
- BThrombotic
- CThrombotic
- DEmbolic
11Venous thrombi (red thrombi) typically form via blood stasis in which bodily organ?
The [blank_start]heart[blank_end]
Would this cause an embolic or thrombotic cerebral infarction?
[blank_start]Embolic[blank_end] cerebral infarction- Aheart
- BEmbolic
12In which artery of the brain is a thrombus most likely to form?
- AAnterior cerebral artery
- BMiddle cerebral artery
- CPosterior cerebral artery
13Approximately 48 hours after a cerebral infarct, neutrophils are no longer the predominant cell type. What is the dominant cell type?
[blank_start]Microglial[blank_end] cells- AMicroglial
14In terms of Haemorrhagic infarcts, match the site of lesion to the clinical findings.
[blank_start]Carotid artery disease[blank_end]: Contralateral weakness or sensory loss. If dominant hemisphere may experience aphasia/apraxia
[blank_start]Middle cerebral artery[blank_end]: Weakness predominantly contralateral face and arm
[blank_start]Anterior cerebral artery[blank_end]: Weakness and sensory loss in contralateral leg
[blank_start]Vertebro-basilar artery disease[blank_end]: Vertigo, Ataxia, Dysarthria, Dysphagia, among other brain stem syndromes- ACarotid artery disease
- BMiddle cerebral artery
- CAnterior cerebral artery
- DVertebro-basilar artery disease
15Which clinical condition is the biggest risk factor for stroke?
[blank_start]Hypertension[blank_end]- AHypertension
16Hypertension typically predisposes to which type of stroke?
- ATotal Anterior Circulation Syndrome
- BPartial Anterior Circulation Stroke
- CPosterior Circulation Syndrome
- DLacunar Stroke
17What is the most common type of stroke?
[blank_start]Lacunar[blank_end] stroke- ALacunar
18Intracerebral haemorrhages most typically occur in the ...
- ABasal Ganglia
- BThalamus
- CCerebellum
19What are the most common vascular malformations?
- ACavernous angiomas
- BVenous angiomas
- CCapillary telangiectases
- DArteriovenous malformations
20Arteriovenous Malformations...
Involve shunting from [blank_start]artery to vein[blank_end], leading to formation of easily ruptured smooth muscle and aneurysms
Typically occur in the territory of the [blank_start]middle[blank_end] cerebral artery- Amiddle
- Banterior
- Cposterior
- Dartery to vein
- Evein to artery
21Subarachnoid haemorrhages most typically occur due to rupture of [blank_start]berry[blank_end] aneurysms. 90% of subarachnoid haemorrhages occur in the territory of the [blank_start]internal carotid[blank_end] artery.
- Ainternal carotid
- Bberry
