Fibre is not digested in our diet. Many foods contain varying types of dietary fibers, all of which contribute to health in different ways. The epimysium surrounds bundles of nerve cells that run in long fibers, called fascicles. Spindle fibers are aggregates of microtubules that move chromosomes during cell division. Unwanted particles escaping the gut and entering the bloodstream can cause an autoimmune response like asthmatic inflammation. -fiber is the oldest plant fiber to make cloth; soft, luxurious, and flexible; stronger than cotton but less elastic-best grades are used for linen fabrics such as damasks, lace, and sheeting-coarser grades used for the manufacturing of twine and rope Extracellular filamentous structures such as collagenous elastic connective tissue fibers.
