fibril
Microscopic tissue strand
A fibril is a small fiber or threadlike structure, especially one that is part of a larger fiber.
The term appears mainly in scientific contexts—muscle fibrils, nerve fibrils, protein fibrils.
In biology and medicine, fibrils are the fine structural components that make up tissues: The collagen fibrils give tendons their strength.
