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

2- the section does not reveal the cells that were present in front and behind this particular tissue section.
3- the section does not always reveal the angle at which an organ was sectioned.
For these reasons, sections must always be examined very carefully to correctly interpret their components and their organization.
