Hyaline, Elastic, and Fibro Cartilage

Hyaline Cartilage
  • Toggle Item
    Hyaline 4X
    A: Perichondrium lines the outside of the hyaline cartilage and acts like a capsule it is DCCTRA.

    B: Chondroblast layer are transformed fibroblasts that are starting to enlarge and synthesize their own cartilage matrix. These cells are much smaller and thinner than the fully mature chondrocytes.

    C: Chondrocytes completely surrounded by matrix. The chondrocytes are located inside lakes called lacunae.

    Hyaline Cartilage as a whole is considered DCCTRA

    Hyaline 20X
    A: Perichondrium is DCCTRA

    B: Chondroblast layer

    C: Nest cells are lacunae with 2 or more cells

    Hyaline 40X
    A: Lipid droplet

    B: Nest cell with two visible cells
Elastic Cartilage
  • Toggle Item
    Elastic 4X
    A: Elastic cartilage

    B: Adipose tissue

    C: Stratified squamous epithelium
  • Toggle Item
    Elastic 10X
    A: Adipose tissue

    B: Perichondrium is DCCTRA and surrounds the entire portion of the elastic cartilage

    C: Chondroblast layer is a layer of very thin cells just beneath the perichondrium

    D: Elastic cartilage is considered DECTRA. The elastic fibers are very noticeable because they stain black and the fibers can be seen.

    Elastic 20X
    A: Perichondrium stains a light pink color. DCCTRA

    B: Chondorblast layer has much thinner cells with less elastic fibers

    C: Elastic fibers stain dark and can be seen in abundance between the cells. DECTRA

    D: Nest cell with two individual cells in one lacunae
  • Toggle Item
    Elastic 40X
    A: Nest cell

    B: Elastic fibers cause this tissue to be named DECTRA
Fibrocartilage
  • Toggle Item
    Fibrocartilage 4X
    A: Fibrocartilage is called DCCTIRA due to the irregular arrangement of the fibers

    B: Pubic bone that the fibrocartilagenous pubis symphysis attaches to

    Fibrocartilage can be distinguished from hyaline and elastic cartilage because it does not have a perichondrium or a chondroblast layer
  • Toggle Item
    Fibrocartilage 20X
    A: Chondrocytes within lacunae

    B: Bone
  • Toggle Item
    Fibrocartilage 40X
    A: Fibrocartilage matrix

    B: Nest cell
  • Toggle Item
    Fibrocartilage
    A: Chondrocytes

    B: Irregularly arranged dense collagenous fibers
