  1. Fibril

    Fibrils (from the Latin fibra) are structural biological materials found in nearly all living organisms. Not to be confused with fibers or filaments, fibrils tend to have diameters ranging from 10-100 nanometers (whereas fibers are micro to milli-scale structures and filaments have diameters approximately 10-50 nanometers in size). Fibrils are not usually found alone but rather are parts of greater hierarchical structures commonly found in biological systems. Due to the prevalence of fibrils in biological systems, their study is of great importance in the fields of microbiology, biomechanics, and materials science.


  1. fibril

    A fibril is a small or slender fiber, either isolated or part of a larger structure. They are often found in biological structures or materials, such as muscle tissue or plant matter, and are important for their structural or functional roles.

Webster Dictionary

  1. Fibrilnoun

    a small fiber; the branch of a fiber; a very slender thread; a fibrilla

  2. Etymology: [F. fibrille, dim. of fibre, L. fibra.]


  1. Fibril

    Fibril is a fine fiber, such as a myofibril or neurofibril. Neurofilaments are about 10 nanometers in diameter. Cytoplasmic fibrils are observed on the protoplasmic cylinders found in most spirochetal species, although no function of the cytoplasmic fibrils has been ascribed. Polysaccharides, the union of several linked monosaccharides, sometimes serve as a structural compound. Cellulose, the most abundant organic compound on Earth, forms cable-like strings, known as fibrils in the tough walls that enclose plant cells. While cellulose is a compilation of glucose monomers, they form unbranched, long strands instead of coils like starch or glycogen. These are arranged in parallel lines which form on top of each other in an intricate layer through hydrogen bonding. Insect flight muscle is said to be fibrillar, in that it contracts in response to being stretched by antagonistic muscle, so as to allow very rapid contraction.
