44 Questions
Cytopreparatory Techniques are critical laboratory skills taught in tertiary cytopathology courses across Zambian universities and colleges, including the University of Zambia's Biomedical Sciences program. This topic covers the methods for preserving, processing, and staining cytological specimens to ensure optimal morphological detail for diagnosis. Students learn about various fixatives like ethanol, …
Normal Gynecological Cytology
43 Questions
Normal Gynecological Cytology is a fundamental topic for tertiary students in Zambia pursuing diplomas, advanced diplomas, or degrees in Biomedical Sciences, Cytotechnology, or related health programs. This module provides an in-depth understanding of the anatomy, histology, and cytology of the female genital tract, with a focus on the normal cellular …
Microtome Knives and Sectioning Tools
15 Questions
In this tertiary-level topic, Zambian university and college students in biomedical science and laboratory technology programs will study microtome knives and essential sectioning tools. The module covers knife profiles—including plano-concave, biconcave, wedge, and tool-edge shapes—and their suitability for different tissues and microtomes. It also examines materials used in knife fabrication, …
Electron Microscopy in Pathology
2 Questions
Electron Microscopy (EM) provides ultra-structural visualization of tissues and cells, far beyond the resolution of light microscopy, and is an essential topic in advanced cellular pathology. This module covers the theoretical aspects and instrumentation of both Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM), highlighting their differences and applications. …
Freeze Drying and Freeze Substitution
8 Questions
Freeze drying and freeze substitution are advanced research-oriented techniques covered in tertiary cellular pathology and histochemistry courses at Zambian universities. This topic delves into the multi-stage process of freeze drying (quenching, drying, fixation, embedding), where tissue is rapidly frozen and water is removed via sublimation under vacuum. Freeze substitution involves …
Wax Infiltration, Embedding, and Tissue Orientation
14 Questions
Wax infiltration and embedding are the final, crucial steps in tissue processing, transforming cleared tissue into a solid paraffin block ready for microtomy. This advanced tertiary topic, taught in Zambian college and university programs in cellular pathology, covers the principles of vacuum-assisted wax infiltration, the properties and additives of paraffin …
Acid Decalcification Methods
15 Questions
Acid decalcification is the most commonly employed technique in histopathology, and this tertiary-level topic provides an in-depth exploration for Zambian university and college students in biomedical science and laboratory technology programs. The module distinguishes between strong inorganic acids (e.g., nitric, hydrochloric) and weak organic acids (e.g., formic, acetic), detailing their …
Alcian Blue Staining for Acidic Mucins and Proteoglycans
3 Questions
Alcian blue is a cationic copper phthalocyanine dye used to demonstrate acidic carbohydrates, a key technique in the special stains arsenal taught at Zambian tertiary institutions. This topic explains the electrostatic principle: the positively charged dye binds to negatively charged carboxylate and sulfate groups on acidic mucins (sialomucins, sulfomucins) and …
