Filamentous refers to a structure that is thread-like or elongated, resembling a thin filament. This term is often used in biology to describe certain types of organisms, such as filamentous fungi or bacteria, which have long, thin strands. In other contexts, it can describe materials or structures that are composed of or resemble fine threads.
You shouldn't call them anything.
E. coli is a gram negative rod shaped bacteria (it is long and thin).
Some bacteria have flagella, which appearance resembles a long thin tail. They use this to move around. Others "squirm" and glide.
In interphase, chromosomes appear as long, thin, and uncoiled structures known as chromatin threads.
I think it is called Sinew.
Long threads made of actin are called actin filaments, also known as microfilaments. Actin filaments are an important component of the cytoskeleton in cells and play a critical role in cell structure, movement, and division.
tenau is thin.
If you talk about the whip used by the ringmaster, the French call it chambriere (chambrière): A long, thin handle, and a long, thin lash, used during the Liberty Horse Act. Whips used by animal trainers (so-called "lion tamers") have no specific name to my knowledge.
Call manes are used to protect the delicate skin underneath the Macor. It is a long thin stripe of jellyfied muscle beneath the Amior!
chromatids
Filaments are long, thin threads or fibers typically made of materials like glass or metal. They are commonly found in light bulbs and 3D printers, where they are heated to produce light or shapes, respectively.
