Analyzing the genetic material within cells
Which of the following is NOT a basic step in preparing tissue for histopathological study?
Cell theory
What is the difference between biopsy and autopsy in terms of tissue examination?
Autopsy involves examining post-mortem tissue, while biopsy involves examining tissue from a living body
Which technique involves the growth of cells in an artificial environment outside the organism?
Cell culture
Fluorescence in situ Hybridization (FISH) is a technique commonly used in histological analysis.
False
Biopsy is the examination of post-mortem tissue.
False
Cell theory states that all living organisms are composed of cells.
True
Cell culture involves the in vivo growth of cells within an organism.
False
Immunohistochemistry (IHC) is a technique used to detect and localize antigens in tissue samples using antibodies.
True
Match the following tissue examination techniques with their descriptions:
Immunohistochemistry (IHC) = Technique used to detect and localize antigens in tissue samples using antibodies Fluorescence in situ Hybridization (FISH) = Technique commonly used in histological analysis involving the use of fluorescent probes to detect specific DNA sequences Biopsy = Examination of tissue taken from a living body Cell culture = In vitro growth of cells in an artificial environment outside the organism
Match the following terms with their correct definitions:
Histology = Microscopic study of tissue Homeostasis = Maintenance of internal stability and balance within an organism Necropsy = Examination of tissue taken from a dead animal Fixing = Initial step in tissue preparation involving preserving the tissue structure
Match the following types of epithelium with their descriptions:
Stratified epithelium = Epithelial tissue composed of multiple layers of cells Cuboidal epithelium = Epithelial tissue with cube-shaped cells Columnar epithelium = Epithelial tissue with tall, rectangular-shaped cells Simple squamous epithelium = Single layer of flattened cells forming a smooth surface
Match the following steps in tissue preparation with their correct order:
Fixing = Preserving the tissue structure Processing = Dehydration, clearing, and infiltration of the tissue Embedding = Encasing the tissue in a solid medium for sectioning Mounting = Placing the sliced tissue on a slide for microscopic examination

All living organisms are composed of cells. = Accurate statement according to cell theory Cells can only arise from pre-existing cells. = Accurate statement reflecting cell theory principle Cells are all identical in structure and function. = Inaccurate statement based on cell theory Cell culture involves the in vivo growth of cells within an organism. = Inaccurate statement about cell culture
This quiz covers the demonstration of lysozyme-containing structures in scattered macrophages and large clusters of cells, along with the counterstaining of nuclei with hematoxylin. It also includes information about live cell and tissue culture for studying cellular behavior outside the body. Test your knowledge on these topics!
