| Many such pairs of filaments are bundled together into a structure called a fibril, and groups of fibrils make up a single muscle fiber. |
| Besides studying fibrils in the test tube, researchers would like to make computer models to view fibril formation. |
| The simultaneous occurrence of random aggregation and amyloid fibril formation has been observed before. |
| As the number of fibrils decreases, it becomes increasingly easier to cut the next fibril because the fibrils carry larger and larger loads. |
| In particular, the mineral completely encases each fibril, enclosing the fibrillar volume. |
| Thus, each plant cell can be viewed as making its own cellulose fibril cocoon. |
