Study Notes
Cartilage Structure and Function
- Perichondrium functions as a nutritive layer that supplies cartilage with oxygen and nutrients.
Types of Cartilage
- Elastic cartilage is found in the external ear and the auditory tube.
Hyaline Cartilage
- Hyaline cartilage is translucent grey-blue in its fresh state.
- Hyaline cartilage is commonly found in the respiratory passages, trachea, bronchi, and in the articular cartilage of joints.
- Chondroblasts in hyaline cartilage produce the cartilage matrix and are located in the perichondrium.
- Chondrocytes are mature cartilage cells located within the cartilage matrix, and their primary function is to maintain the matrix.
- The matrix of hyaline cartilage is composed of a gel-like substance with sparse, fine collagen type II fibers that are not visible under a light microscope.
- The main component of hyaline cartilage matrix is chondroitin sulfate.
Chondrocytes and Chondroblasts
- Chondrocytes are responsible for maintaining the cartilage matrix, responding to growth factors, and producing matrix components.
- Chondrogenic cells, also known as stellate or spindle-shaped primitive mesenchymal cells, are located in the perichondrium during chondrogenesis and differentiate into chondroblasts.
- Chondroblasts are located in the perichondrium and are responsible for producing the cartilage matrix.
Vascularization
- Hyaline cartilage is considered avascular because it lacks a direct blood supply, relying on diffusion from surrounding tissues.
