Resumo de Recurso
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
