Cartilages
Cartilages
Cartilages (pronunciation: /ˈkɑːr.tɪ.lɪdʒ/) are a type of Connective tissue found in many areas of the body including the Joints, Rib cage, Ear, Nose, Bronchial tubes, and Intervertebral discs. They are composed mainly of Water, Collagen, and Proteoglycans.
Etymology
The term "cartilage" is derived from the Latin cartilago, meaning "hardened tissue".
Types of Cartilages
There are three main types of cartilages in the human body:
1. Hyaline cartilage: This is the most common type of cartilage. It is found in the Nose, Trachea, and at the ends of the Long bones where it provides cushioning.
2. Elastic cartilage: This type of cartilage is found in the Ear and Epiglottis. It is more flexible than hyaline cartilage.
3. Fibrocartilage: This is the strongest and most durable type of cartilage. It is found in areas of the body that need to withstand heavy loads, such as the Intervertebral discs and the Knee.
Functions of Cartilages
Cartilages serve several important functions in the body:
- Shock absorption: In the Joints, cartilages act as a cushion between the Bones, absorbing the impact of movement.
- Facilitate movement: Cartilages in the Joints allow for smooth movement by reducing friction.
Related Terms
- Chondrocyte: This is the cell type that produces and maintains the cartilaginous matrix.
- Chondrogenesis: This is the process by which cartilage is formed.
- Osteoarthritis: This is a degenerative joint disease that involves the breakdown of cartilage in the joints.
