- ACoronary Artery Disease
- BStroke
- CDeath
- DPeripheral Artery Disease
- ECentral Artery Disease
2There are two major categories of stroke. 80% are which one?
- AIschaemic
- BHaemorrhagic
3Platelets are disc-shaped fragments produced by __________.
- AMegakaryotes
- BMegakaryocytes
- CMinikaryocytes
- DMinikaryotes
- ESpleen
- FBlasts
4Average platelet count is:
- A150,000 – 400,000 / μL
- B150 – 400 / μL
- C1,500 – 4,000 / μL
- D15,000 – 40,000 / μL
- E150,000 – 40,000 / μL
5Which of the following are functional responses of platelets?
- APrimary adhesion
- BShape change
- CAggregation
- DGranule release
- EProcoagulant function
- FAnticoagulant function
- GSecondary adhesion
- HAntiapoptotic function
- IProapoptotic function
- JCarry Oxygen
6Shape change is a crucial functional response of platelets to …something. They change shape from [blank_start]__________[blank_end] to [blank_start]__________[blank_end]
- AFlat disc
- BSpiny disc
- CSpiny sphere
- DSmooth sphere
7Which receptor/ligand interactions occur during which bit?
- AGPIb/V/IX – vWF
- BαIibβ3 – fibronectin, VWF
- CαIibβ3 – fibrinogen, fibronectin
- DGPIb/V/IX – vWF
- EαIibβ3 – fibronectin, VWF
- FαIibβ3 – fibrinogen, fibronectin
- GGPIb/V/IX – vWF
- HαIibβ3 – fibronectin, VWF
- IαIibβ3 – fibrinogen, fibronectin
8Fibrin generation at the site of vascular injury has a crucial role in anchoring the thrombus to the vessel. It requires initiation of coagulation and generation of thrombin. This depends on Tissue Factor (TF) expression on the surface of [blank_start]__________[blank_end] and fibroblasts.
- ASmooth Muscle Cells (SMCs)
- BVascular Endothelial Cells (VECs)
- CVascular Epithelial Cells (VECs)
- DSkeletal Muscle Cells (SMCs)
- ECardiac Muscle Cells (CMCs)
9Platelet-mediated fibrin clot retraction shrinks the size of the blood clot. Thought to be important for stabilising the clot against shear forces of blood flow. This requires:
- AIntegrin αIIbβ3
- BFibrin
- CMyosin/contractile force
- DActin cytoskeleton
