Cartilages are classified into three main types based on their composition and structure:
1. Hyaline cartilage: This is the most common type of cartilage and is found in the joints, respiratory tract, and rib cage. It is smooth and flexible, with a glassy appearance. Hyaline cartilage provides support and cushioning to joints and helps maintain the shape of certain structures in the body.
2. Elastic cartilage: This type of cartilage contains a higher proportion of elastic fibers, making it more flexible and elastic than hyaline cartilage. Elastic cartilage is found in the external ear, epiglottis, and larynx, where flexibility and resilience are important for function.
3. Fibrocartilage: Fibrocartilage is the strongest type of cartilage and contains a higher proportion of collagen fibers, giving it a tough and durable structure. Fibrocartilage is found in the intervertebral discs, pubic symphysis, and certain tendons and ligaments, where it provides support and helps absorb shock and pressure.

Hyaline cartilage
- Matrix: Glassy, homogeneous
- Cells: Chondrocytes in isogenous groups within lacunae
- Perichondrium: Present
- Location: articular surfaces of joints, costal cartilage, nose, trachea
Elastic cartilage
- Matrix: More flexible than hyaline due to presence of elastic fibers
- Cells: Chondrocytes in pairs in lacunae
- Perichondrium: Present
- Location: ear pinnae, epiglottis, eustachian tubes
Fibrocartilage
- Matrix: Collagen fibers oriented in different directions
- Cells: Chondrocytes in rows between collagen bundles
- Perichondrium: Usually absent
- Location: intervertebral discs, menisci of knees, pubic symphysis
