Total questions: 10
Worksheet time: 3mins
Which cell type is a stable cells
Skeletal muscle
Neurons
Endocrine glands
Haematopoietic cells
Listed below are common adaptive cellular changes EXCEPT:
Atrophy
Hypertrophy
Hyperplasia
Dysplasia
Listed below are characteristic of atrophy and hypertrophy EXCEPT:
Hypertrophy occurs due to increase amounts of structural proteins and organelles
Hypertrophy only occurs in permanent cells
Aging is a cause of atrophy
Atrophy occurs due to decreased protein synthesis, increased protein degradation in cells & autophagy
Which is the correct description of figure above?
Intestinal metaplasia in Barrett oesophagus
Squamous metaplasia in lung tissue among smokers
Brain atrophy
Acute myocardial infarction
Which is the statement below is TRUE?
Hyperplasia is increase in the size of cells leading to increase in the size of the organ
Hypoplasia is incomplete development or underdevelopment of an organ or tissue
Aplasia is abnormal proliferation of cells in an organ
Endometrial hyperplasia is an example of physiologic hyperplasia
Define metaplasia
Metaplasia is replacement of one differentiated cell type by another differentiated cell type, normally as a result of chronic irritation
Metaplasia is complete absence of an organ due to failure of development of the embryonic tissues or cells.
Metaplasia is disordered cell growth with loss of cellular uniformity and architectural orientation
Metaplasia is decrease in cell size causing a reduction in the size of tissue or organ
Which is the best description for the above figure?
Acute myocardial infarction
Left ventricular hypertrophy following chronic hypertension
Skeletal muscle hypertrophy in bodybuilder
Brain atrophy
Below is correct descriptions regarding metaplasia EXCEPT:
Squamous metaplasia in smoker's lung is an example of metaplasia
Metaplasia makes cells better able to withstand the stress
Dysplasia is a complication of metaplasia
Myositis ossificans is not an example of metaplasia
The statements below are true EXCEPT:
Metaplasia can leads to malignancy.
Dysplasia is disordered cell growth with loss of cellular uniformity and architectural orientation.
Left ventricular hypertrophy is an example of irreversible changes
Pathologic hyperplasia can leads to malignancy
Which of the cellular adaptation occurs in the figure above?
Intestinal metaplasia in Barrett oesophagus
Myositis ossificans
Squamous metaplasia in smoker's lung
Dysplasia of squamous epithelium
