Filamentation, which refers to the formation of thin, thread-like structures, can be described in many ways using a variety of synonyms. For instance, other terms that are often used to describe the process of filamentation include fibrillation, fibrin formation, fibrillogenesis, fiber formation, fiber elongation, and fiber growth. Depending on the field of study, even more specific synonyms may be used; for example, in microbiology, filamentation may be referred to as pseudohyphal growth or simply hyphal growth. Regardless of the terminology used, the essential concept of filamentation remains the same: the formation of long, thin structures from smaller building blocks.
