Dense Irregular Connective Tissue-Eyelid

Taut, fiber-rich connective tissue, which must withstand mechanical stress,  is characterize d by the arrangement of intercellular supportive structures.  This figure shows a planar cut through the lid plate (tarsus, collagen fiber plate ) of the upper lid. There are densely intertwined bundles of f ibers that run in ever y direction ( woven connective tissue ). This fiber arrangement ascertains a reliable tensile strength in all directions. Sporadically, vessels are cut. Cells are sparse, and fibers dominate the structure.  This braid-like connective tissue (taut, dense connective tissue) is also found in the capsules of many organs, the corium ( stratum reticulare of the corium), the dura mater and the sclera . Human upper eyelid.
