Course objectives
Course of human cytology, histology and embryology consists of two complementary parts - general histology and embryology.
Course objectives
At the end of the course students should be able to:
- describe both general cell structures as well as specific ultrastructural modifications of particular cell types
- understand classification, organization and basic structural principles and function of tissues and organs
- characterize epithelial, connective, nerve and muscle tissues, emphasising common aspects of different tissue types as well as features of particular tissues
- identify tissues in different histologic slides.
- describe gametogeneis and its regulation on both organ and systemic levels
- define the early embryonic development as well as development of fetal membranes, placenta, umbilical cord and extraembryonic structures generally.
- characterize stages of embryonic development as well as developmental abnormalities
Syllabus
  • Cytology and general histology: The object and the significance of the histology. Brno histological and embryological school. Methods used in study of cells and tissues. Sampling, fixation and embedding of tissues for histological examination. Sample preparation for examination by electron microscopy.
  • Cell definition, its size, shape and viability. Composition and structure of the protoplasm. Cell surfaces and intercellular connections. Structure and function of the nucleus. Structure and function of cell organelles. Cell inclusions. Cytoskeleton. Cell growth, aging, and degeneration of cells. Mitosis. Meiosis.
  • Cell differentiation and morphogenesis of tissues. Definition of the tissue.The most important structural and functional characteristics of the tissues.
  • Definition of the epithelial tissue. Classification of epithelia. Covering epithelia (epi-thelial membrane) - classification and chief distribution. The glandular epithelium -types of glands. Absorptive, respiratory and sensory epithelia.
  • Structure, origin and types of the connective tissue. Ground substance and fibers. Connective tissue proper - types, chief distribution, and function. Cartilage and bone types, chief distribution, and function. Ossification. The joints.
  • Muscular tissue - characteristic and classification. Smooth muscle tissue. Skeletal muscle tissue. Submicroscopic structure of the muscle fiber, ultrastructure of the myofibrils, definition of sarkomere. Mechanism of the muscle contraction. Cardiac muscle tissue.
  • Nervous tissue - definition. Neurons - structure and classification. Sheathes of nerve fibers. Synapsis, its structure and function. Nerve endings. Neuroglial cells.
  • Composition of the human peripheral blood. Cytology of formed elements of blood (erythrocytes, leukocytes, thrombocytes). Differential white cell count. Prenatal and postnatal haemopoiesis. Microscopical structure of the bone marrow and its classicication. Development of blood cells.
  • General embryology: Gametogenesis. Oogenesis, structure of the oocyte during ovulation. The ovarian and menstrual cycles - correlation. Meiosis - the differences between spermatogenesis and oogenesis. Composition of ejaculate, normal count of spermatozoa (normospermy). Properties of the spermatozoa.
  • Fertilization and cleavage of the human ovum. The morula and blastocyst. Implantation of the conceptus. Abnormal implantation sites, tubal pregnancy. Changes in the blastocyst during implantation. Germ disc, development of axial formations. Notogenesis - development of notochord (= chorda dorsalis).
  • Somitomeres (somites) - their development and differentiation. Intra- and extraembryonic mesoderm. Origin of mesenchyma.
  • The germ disc and its differentiation. Development of external appearance of embryo. Development of limbs. Human fetal membranes - amniotic sac, yolk sac, chorion, and decidua. Development of the placenta and the umbilical cord. Blood circulation in the placenta. Anomalies of the placenta and the umbilical cord. Placenta praevia, accreta, and increta.
  • Growth of embryo in the uterus. Monthly position of the uterus during pregnancy. Presentation, position and posture of fetus. Marks of mature and full-term fetus, the rule of Hasse. Delivery of a fetus.
  • Multiplied number of embryos: mono- and dizygotic twins and triplets; frequency. Arrangement of fetal membranes in multiplets.
  • Congenital malformations - critical periods of origin, main teratogens.
