Framework
When studying Histology, it is useful to have a framework to assist in structuring your approach. For all slides, you will be expected to know one or more of the following concepts:
- Cells
- Tissues
- Organs
- Structures
- Functions
Cells
Each cell contain 1 nucleus. The cell membrane is not visible, but between each nucleus a line can be drawn to demarcate the cell border. Cells can roam on their own, or be contained inside tissues or organs. Each type of cell will have its own function.
Tissues
Tissues can consist of cells, fibres or filling in the form of amorphous ground substance. Tissues can be located in an organ, or fill areas between organs.
Organs
Organs consist of cells and tissues and can contain structures. The cells, tissues and structures of an organ work together to perform the functions of that organ.
Structures
Structures are parts of an organ or a small part of the body. A structure can contain cells and tissues. In an organ, structures contribute towards the function of the organ.
Function
Cells, tissues, organs and structures have functions that perform normally in the body. When they do not function normally, a disease process can be diagnosed.
Task 2
A diagram to indicate the relationship between cells, tissues, organs, structures and their functions:
