Cartilage
- Hyaline Cartilage
- nose, larynx, trachea, bronchi
- Developement
- Mesenchymal cell
- Chondroblast (young cell)
- Chondrocyte (Adult cell)
- enclosed in LACUNA
- Many Lacuna >> Cell nest
(isogeneous cellgroup)
- สร้าง GS+fibers = Matrix
- Surrounds lacunae
- Territorial matrix (darker stain)
- glycosaminoglycan > collagen
- Between lacunae
- Interterritorial matrix (Paler stain)
- Perichondrium
- Outer: Fibrous layer
[collagen&fibroblast]
- Inner:Cellular
(chondrogenic) layer
[chondroblast]
- Growth
- Interstitial (mitosis)
- Appositional
- Structure
- Near perichondrium
- small, elliptical lacunae,
parallel to the surface
- Deep
- larger, polyhedral shape
- Nutrition
- Cartilage is non vascular
- Chondrocytes get
nourishment from diffustion
through the matrix
- Calcification
- Chondrocyte will be died
- start to make the real BONE
- Elastic Cartilage
- external ear, epiglottis, auditory
canal, corniculat&cuneiform
cartilage of larynx
- Similar structure to hyaline cartilage
but HAVE ELASTIC FIBER
- Fibrocartilage
- found where tendon
attaches to bone,
intervertebral disks,
meniscus(stifle joint),
dog heart
- transitional between cartilage and CNT
- Structure
- a lot of collagen fibers in ECM
- Bundles parallel to the direction of stress
- chondrocyte located in rows of small
lacunae between collagen bundles
- *NO difinitive perichondrium
