The body will be conceived as a functional unit that is much more than the sum of its parts. The levels selected from a large number of organisational levels are those that form the subject of a Histology course. As such, only the microscopic levels, with special attention to the tissue level, are further dealt with in this, timely very limited, acquaintance with histology.
In the discussion of 'tissues', the main cell biological aspects of 'typical' cells in various tissues are related to their function, and the significance of extracellular matrix components is elaborated on. Discussed are:
- epithelial tissue: covering epithelia, including skin and derivatives (integument; cuticle, hairs, nails, ...); glandular epithelia
- connective tissue: 'real' connective tissues; connective tissues with special properties (incl. fat tissues); supporting tissues (incl. cartilage; bone tissues; bone formation and development)
- muscle tissue: skeletal muscle; smooth muscle; hart muscle
- nerve tissue
The practical exercises ...
- aim at familiarising students with the optimal use of a good light microscope
- focus on learning to recognise cells and tissues in microscopic preparations and on acquiring a spatial insight into microscopic structures
- are intended to study microscopic preparations of animal tissues in various organs
