ELASTIC CARTILAGE Location: _____ FIBROCARTILAGE – Tough, shock absorbing. They are less abundant than the collagen varieties :) Ligament, tough fibrous band of connective tissue that serves to support the internal organs and hold bones together in proper articulation at the joints. Distinction between these fibers is based on their staining characteristics and their location in dermis. The scientists came up with a fast and easy method for embedding different kinds of microstructures in super-elastic fibers. Altered elastic fibers have green-yellow autofluorescence with ultraviolet light (Diagn Cytopathol 2002;26:310) Positive stains Vimentin , elastic stains (fibers have dense core and irregular margins), CD34 in spindle cells ( Virchows Arch 2006;448:195 ) 12). Though they may be highly resemblant clinically, the main differences can be noted histologically in the location of the absent elastic fibers but also in severity of ultrastructural damages . Adipose Tissue : this type of tissue differs from other connective tissues in two respects: it contains more of fat cells and not the intercellular substances and secondly, each fat cell is surrounded by its own basal lamina . Elastic fibers; Description: This cartilage is similar to hyaline cartilage, but it contains many more elastic fibers [3]. Traditional elastic fibers, such as spandex or Lycra, have been commercialized for many years. On most slides, the elastic fibers [3] stain with a darker stain so you can see the elastic network that is formed.
