Topics for Anatomy and Physiology
Find educational topics for Anatomy and Physiology aligned with the Zambian tertiary curriculum.
Urothelium: Urinary Tract Only
No questions yet
Epithelial distribution for Zambian tertiary histology students. Urothelium lines urinary bladder, ureters, renal calyces, proximal urethra. NOT in blood vessels (endothelium). Critical distracter elimination. Umbrella cells provide barrier function and compliance. High-yield OSPE content.
Microglia
No questions yet
CNS macrophages for Zambian students. Resident immune cells of brain and spinal cord. Phagocytic, respond to injury. Part of macrophage naming system. High-yield.
Chondrocyte Identification
No questions yet
Connective tissue cytology for Zambian tertiary students. Chondrocytes = cartilage cells, located in lacunae. NOT osteocytes (bone), fibroblasts (CT proper), or adipocytes (fat). Maintain cartilage matrix (collagen, proteoglycans). Avascular tissue. Fundamental histology identification.
Gap Junctions
No questions yet
Communication junctions for Zambian students. Connexons allow ion/small molecule passage. Cardiac muscle, smooth muscle. Electrical coupling. Distinguish tight/desmosomes.
Tight Junctions
No questions yet
Sealing junctions for Zambian students. Zonula occludens. Prevent paracellular leakage. Blood-brain barrier, intestinal epithelium. Occludin, claudin proteins.
Elastic Cartilage: Ear and Epiglottis
No questions yet
Cartilage subtype locations for Zambian tertiary anatomy students. Elastic cartilage found in external ear (auricle) and epiglottis. Contains elastin fibers for flexibility. Distinguish from hyaline (joints, nose, ribs, trachea) and fibrocartilage (intervertebral discs, pubic symphysis).
Simple Epithelium
No questions yet
Single layer classification for Zambian students. One cell layer. Function: absorption, secretion, filtration. Locations: alveoli, kidney tubules, endothelium. Contrast stratified.
Pseudostratified Epithelium
No questions yet
False stratified for Zambian students. Appears layered but all cells touch basement membrane. Ciliated type in trachea with goblet cells. Nuclei at different levels.
Transitional Epithelium
No questions yet
Urothelium for Zambian students. Stretchable, changes appearance. Dome-shaped umbrella cells. ONLY in urinary tract. Permeability barrier, compliance. High-yield.
