|
chondrocytes; ocupy lacunae; nucleus; well developed RER; cytoplasm rich in glycogen; lipid droplets present |
|
|
chondrocytes in hyalin; clustered in isogenous groups; territorial matrix is more basophilic due to more abundant GAGs |
|
|
from left to right: perichondrium in hyaline (contains fibroblasts), chondroblasts; chondrocytes |
|
|
types of cartilage: classified based on amount of collagen or elastic fibers in extracellular matrix |
|
|
hylaine cartilage: reinforced by collagen type 2Fetal axial and appendicularskeleton; Growth plates – physis; Articular cartilage; Costo-chondral junctions; Nasal septum, larynx, trachealrings, bronchi. |
|
|
elastic cartilage: has perichondrium; chondroblasts and chondrocytes in lacunae; contains abundant elastic fibers-flexible; Found in the larynx (epiglottis and the corniculate andcuneiform processes of the arytenoid cartilage), in theexternal auditory canal and in the ear pinna. |
|
|
hyaline cartilage growth plate: (from the left) zone of resting/reserve cells; zone of proliferation; zone of hypertrophic cells (interstitial growth) |
|
|
elastic cartilage; with perichondrium; grows occurs by both appositional and interstitial growth |
|
|
fibrocartilage: lacks perichondrium-cannot regenerate; contains chondrocytes and dense fibrous CT (collagen type 1); Found in intervertebral discs,menisci, insertions of tendons,mandibular symphysis, pubicsymphysis |

|
|
osteoblasts osteocytes |
|
|
