Block1/Fig 7. W3240, Mesentery, FeCl3-hematoxylin

block1_20.jpg - Fig 7. W3240, Mesentery, FeCl3-hematoxylin. Looseconnective tissue is characterized by loosely arranged fibersand abundant cells as compared to the dense connectivetissue. The ground substance occupies more volume than thefibers do. This slide depicts a whole mount (wm) ofmesentery through it's entire thickness. The semifluid groundsubstance through which tissue fluid percolates is invisible,since it was extracted during the preparation of the slide.However, two types of fibers: the thicker, wavy, ribbon-likecollagen fibers and the thin, straight, branching elasticfibers (EF) are well demonstrated. The mast cells (M) areeasily to be identified, since they are the largest cells in thefield and posses a granular cytoplasm. Nuclei of other celltypes, i.e., lymphocytes, plasma cells, and macrophages, arealso present but are not identifiable.
