fibril
/ˈfʌɪbrɪl
/noun technical
A small or slender fibre: each muscle fibre is subdivided into smaller fibrils...
- As the number of fibrils decreases, it becomes increasingly easier to cut the next fibril because the fibrils carry larger and larger loads.
- Many such pairs of filaments are bundled together into a structure called a fibril, and groups of fibrils make up a single muscle fiber (cell).
- The direction of cell growth is determined by the orientation of the cellulose fibrils in the cell wall.
