Cartilage
HyalineMatrix: Blue-white appearance, glassy, and abundant with collagen
Predominant Cell Type: Chondrocytes and Chondroblasts Function: Support, reinforcement, cushioning Location: Ribs, end of long bones, trachea, and larynx Disease: Osteoarthritis is when the cartilage between the joints becomes inflamed, making it difficult to move the joints. |
Fibrocartilage Matrix: Very similar matrix to hyaline, but less firm
Predominant Cell Type: Chondrocytes and Chondroblasts Function: Compression, cushion, resist shock Location: Between vertebrae and the knees Disease: Fibrocartilaginous Embolism is when there is not enough blood supply to the fibrocartilage in the spine. It can lead to severe pain in the neck and back. Analogy: Fibrocartilage is to the body as bushings are to a skateboard |
Elastic CartilageMatrix: Much less collagen than hyaline with much more elastin
Predominant Cell Type: Chondrocytes and Chondroblasts Function: Support with flexibility Location: Outer ear and epiglottis Disease: Perichondrial hematoma also known as cauliflower ear is when the cartilage in the ear grows back overgrown after and injury. |
