As they are very thin we observe in (almost) two dimensions structures that were previously three-dimensional.<br \/>\nThey need to be studied taking into account that:<br \/>\n1- each section is a small sample of an object many times larger.<br \/>\n2- the section does not reveal the parts of cells and of other structures that were present in front and behind this particular section.<br \/>\n3- the section does not always reveal the angle at which a structure or organ was sectioned.<\/p>\n<p>For these reasons, they must always be examined very carefully to correctly interpret their components and their organization.<\/p>\n<p>Observe the image. Is it all right?
