Histological septa are seen throughout most tissues of the body, particularly where they are needed to stiffen soft cellular tissue, and they also provide planes of ingress for small blood vessels.{{Citation needed|date=August 2024}} Because the dense collagen fibres of a septum usually extend out into the softer adjacent tissues, microscopic fibrous septa are less clearly defined than the macroscopic types of septa listed above.{{Cite book |last1=Burt |first1=Alastair D. |url=https://www.sciencedirect.com/book/9780702033988/macsweens-pathology-of-the-liver |title=MacSween's Pathology of the Liver |last2=Ferrell |first2=Linda D. |last3=Portmann |first3=Bernard C. |publisher=Churchill Livingstone |year=2011 |isbn=978-0-7020-3398-8 |edition=6th |pages=1–77 |language=en |chapter=1 - Anatomy, pathophysiology and basic mechanisms of disease |doi=10.1016/C2009-0-47964-9 |chapter-url=https://www.sciencedirect.com/science/article/abs/pii/B9780702033988000015}} In rare instances, a septum is a cross-wall.
