Quantification of surface of segment of fiber. (A, left panels) SEM images of tendon sections cut at different angles and modeling of tendon sections. Yellow arrows indicate size of a segment of fibers. The length of segment of fibers decreases as cutting angle increases. (A, right panels) Model of the various cut sections based on tightly packaged bundles of wooden sticks of uniform size. (B) Quantification of surface of longest length of segment of fibers; note significant difference between angles. *p < 0.05.
