Study Notes
Cartilage Cells
-
Chondrogenic Cells
- Originate from undifferentiated mesenchymal cells (UMCs)
- Found in the inner cellular layer of the perichondrium
- Differentiate into chondroblasts
-
Chondroblasts
- Originate from UMCs or chondrogenic cells
- Found in the inner cellular layer of the perichondrium
- Function:
- Form cartilage
- Form type II collagen fibers
- Form matrix
- Transform into chondrocytes when surrounded by matrix
-
Chondrocytes
- Originate from chondroblasts
- Found throughout cartilage, either singly or in groups
- Function:
- Continuously form matrix
- Responsible for interstitial growth
- Produce type II collagen fibers in the matrix
Cartilage Types
-
Hyaline Cartilage
- Flexible type of cartilage
- Appears yellow in fresh sections
- Structure: Similar to hyaline cartilage with the addition of elastic fibers in the matrix.
- Sites:
- Costal cartilage
- Articular cartilage
- Trachea and bronchi
-
Elastic Cartilage
- Flexible type of cartilage
- Structure: Same as hyaline cartilage but with more elastic fibers in the matrix
- Sites:
- Ear pinna
- External auditory meatus
- Eustachian tube
- Epiglottis
-
Fibrocartilage

- Matrix contains collagen type I with rows of chondrocytes in between
- Sites:
- Symphysis pubis
- Intervertebral disc
- Mandibular joint
