Question 1 |
Which of the following is not true of stroma cells?
They provide structural and mechanical support to the organ | |
An example is cardiac muscle cells | |
They provide nutrition to the organ | |
An example is nerves | |
An example is connective tissues |
Question 2 |
Which of the following is not a component of connective tissue?
Proteoglycans | |
Glycosaminoglycans | |
Elastin | |
Epithelial cells | |
Collagen |
Question 3 |
Which of the following does not occur during the proliferative stage of wound healing?
Angiogenesis | |
Epithelialisation | |
Formation of a thrombus | |
Contraction | |
Fibrous tissue formation |
Question 4 |
How long is the haemostatic process of wound healing?
<12 h | |
<24 h | |
0-4 days | |
1-14 days | |
Day 21 |
Question 5 |
What is the role of labile cells?
Cells that normally exist in a non-dividing state but may enter the cell cycle in response to certain stimuli, such as cell injury | |
Continuously proliferating in order to replace dead or sloughed-off cells
| |
Non-dividing cells, leads to scar formation | |
Dividing cells, leading to tissue growth | |
Cells that normally exist in a dividing state but may stop dividing in response to certain stimuli, such as cell injury |
Question 6 |
Which of the following is not true of growth factors?
They are proteins that stimulate survival and proliferation of particular cells, as well as migration and differentiation | |
They are produced mainly by macrophages and lymphocytes cells at the site of injury as part of the inflammatory process | |
They are only produced by the parenchymal cells or stroma in response to injury | |
They stimulate entry of the cell into the cell-cycle
| |
They are produced transiently in response to an external stimulus and act by binding to cellular receptors
|
Question 7 |
Which of the following is not true of angiogenesis?
Angiogenesis is the incomplete restoration of architecture and function | |
Angiogenesis is the development of new blood vessels
| |
Angiogenesis is promoted by VEGF
| |
Angiogenesis involves sprouting of new vessels from existing ones – involves endothelial cell proliferation and migration | |
Angiogenesis is critical in the site the site of injury – development of collateral circulations at sites if ischemia occurs |
Question 8 |
Which of the following is not true of healing by first intention?
Easy to suture | |
Linear scars | |
Little granulation tissue visible at incision | |
Complications are common | |
Generally uninfected |
Question 9 |
Which of the following is not a local factor affecting tissue repair?
Foreign bodies | |
Type of wound | |
Circulatory status | |
Mechanical factors | |
Location of wound |
Question 10 |
Which of the following is not a complication of tissue repair caused by inadequate formation?
Keloid formation | |
Dehiscence | |
Rupture | |
Evisceration | |
Ulceration |
