INTERPRETING STRUCTURES IN HISTOLOGICAL SECTIONS
The study of histological sections with a light microscope is always challenging. As they are very thin we observe in (almost) two dimensions structures that were previously three-dimensional.
They need to be studied taking into account that:
1- each section is a small sample of an object many times larger.
2- the section does not reveal the parts of cells and of other structures that were present in front and behind this particular section.
3- the section does not always reveal the angle at which a structure or organ was sectioned.

2- the section does not reveal the parts of cells and of other structures that were present in front and behind this particular section.
3- the section does not always reveal the angle at which a structure or organ was sectioned.
For these reasons, they must always be examined very carefully to correctly interpret their components and their organization.
