Dear students!


Group Dentistry МС-117

Congratulations! 2-nd semester is start!
We are pleased to welcome You to the Department of histology, Cytology, embryology.

On practice class every student needs to have:
1. Medical gown
2. Textbook and histology Atlas
3. Workbook, pen
4. (!!!) Colored pencils
5. Sketchbook (!!!) 
 - album (with 20 or more pages)


Lab. № 1"Cytology, part 1"

(1-st Week 07.02 – 08.02.2019)

 The subject of "histology". Methods histological examination. The technique of histological preparation. Types of dyes. Types of microscopy. The structure of the light microscope and work with it. Histological picture.

The light microscope. Steps for examination a slide in the light microscope, click here


Dear students!

Lab. № 2"Cytology, part 2"

(2-nd Week 11.02 – 16.02.2019)

"Cytoplasm: Inclusions. Non-cellular structures". Micrographs and Slides.

General features of cells as the structural and functional units of all living organisms. Inclusions. Noncellular structures: extracellular substance, symplasts, syncytium.

Histological slides for Examination under the light microscope and sketches in the album:

1.     Symplast – striated skeletal muscle fibers. The section of tongue.   (Stained with Hematoxylin + Eosin)

2.     The intercellular substance of hyaline cartilage. The transverse section of the rabbit rib. (Hematoxylin + Eosin)

3.     Inclusions of glycogen in liver cellsof Axolotl(Stained by the Best' method: Hematoxylin + Carmine)

4.     Lipid inclusions in liver cellsof axolotl (Oxide of osmium + safranin)

5. The inclusions of pigment in the skin cells of a tadpole (not stained)


Lab. № 2 “Cytology, part 2”:

(3-st Week 18.02 – 23.02.2019)

Cellular components. Plasma membrane and other cell membranes: biochemical components; membrane organization; membrane functions (selective permeability, passive diffusion, facilitated diffusion; active transport. Endocytosis: phagocytosis, pinocytosis, receptor-mediated endocytosis. Exocytosis. Storage, transport, and secretion. Cytoplasm. Structure and functions of organelles. Mitochondria. Ribosomes. Endoplasmic reticulum: rough and smooth. Structure, functions. Golgi Complex: structure, functions, location, flow of materials through the Golgi complex. Lysosomes. Peroxisomes. Cytoskeleton. Microtubules, microfilaments, intermediate filaments. Centrioles. Mitotic Spindle Apparatus. Cilia. Flagella. General features of nuclei: major components; nuclear function; nuclear morphology. Nuclear envelope; nuclear pore complexes. Chromatin: nucleosomes; chromatin types; chromatin pattern; chromosomes. Nucleolus. Nucleoplasm. Nuclear functions: cell reproduction; mitosis and interphase; the steps in cell division. The cell cycle. Cellular Differentiation. Cell death: necrosis and apoptosis. Intercellular Junctions.
