Introduction to Carbohydrates in Histochemistry
1 Questions
Carbohydrates are a diverse and functionally critical group of biomolecules extensively studied in tertiary-level cellular pathology and histochemistry at Zambian universities and colleges. This foundational topic introduces the classification of carbohydrates—monosaccharides, polysaccharides, proteoglycans, glycoproteins, and mucins—and their essential roles in cellular metabolism, protein folding, cell adhesion, and immune recognition. Students …
Specimen Grossing and Dissection
25 Questions
Specimen grossing, also known as surgical cut-up or dissection, is the critical first step in the histopathology diagnostic pathway and a core competency in tertiary cellular pathology education at Zambian universities and colleges. This topic encompasses the systematic inspection, description, measurement, inking, and sectioning of surgical and biopsy specimens to …
Laboratory Hazards and Safety in Cellular Pathology
27 Questions
Safety is paramount in the histopathology laboratory, and this tertiary topic equips Zambian college and university students with comprehensive knowledge of hazards and control measures in cellular pathology. The module categorizes health hazards (biohazards, irritants, corrosives, sensitizers, carcinogens, toxins) and physical hazards (ignitables, explosives, oxidizers, mechanical, electrical). Students will learn …
Freeze Artifacts and Tissue Freezing Methods
9 Questions
This tertiary-level topic addresses the challenges and techniques associated with freezing tissue for frozen sections, a key component of histotechnology and diagnostic pathology curricula in Zambian colleges and universities. Students will explore the causes and morphological appearance of freeze artifacts, primarily ice crystal formation, which leads to tissue disruption, holes, …
Dehydration and Clearing in Tissue Processing
39 Questions
Dehydration and clearing are pivotal intermediate stages in tissue processing, extensively covered in tertiary histotechnology curricula at Zambian universities and colleges. Dehydration involves the removal of free water and aqueous fixatives using graded alcohols (e.g., ethanol, methanol), with careful attention to concentration gradients to prevent cell distortion. Clearing follows dehydration, …
Microtome Types and Applications
21 Questions
This tertiary education topic delves into the various types of microtomes used in histopathology and cellular pathology, a core component of diploma and degree programs in medical laboratory science across Zambian colleges and universities. Students will explore rotary, rocking, sliding, base sledge, freezing, vibrating, and ultra-microtomes, understanding their design, mechanisms, …
Periodic Acid-Schiff (PAS) Technique
2 Questions
The Periodic Acid-Schiff (PAS) reaction is the cornerstone special stain for carbohydrates in histopathology, a mandatory topic in tertiary cellular pathology programs across Zambian colleges and universities. This module details the chemical principle: periodic acid oxidizes vicinal diols in sugar residues to create free aldehyde groups, which then react with …
Factors Influencing Decalcification
17 Questions
This advanced tertiary topic examines the key factors that influence the rate and efficacy of decalcification, a core component of histotechnology curricula in Zambian colleges and universities offering programs in medical laboratory science and pathology. Students will analyze variables such as the concentration and volume of decalcifying agents, temperature, agitation, …
Factors Affecting Fixation
14 Questions
This advanced tertiary topic analyzes the multitude of factors that influence the quality and efficacy of tissue fixation, a critical consideration in cellular pathology curricula at Zambian colleges and universities. Students will examine variables including fixative volume (10-20 times tissue volume), duration, time interval to fixation, penetration rate, choice of …
