Functions of Connective Tissue
Connective tissue plays a vital role in providing structure, support, and flexibility to the body. Each type of connective tissue has specific characteristics and functions related to maintaining stability and facilitating movement.
1. Cartilage
- About:
- A firm yet flexible connective tissue found in joints, the rib cage, ear, nose, and intervertebral discs.
- Composed of chondrocytes (cartilage cells) embedded in a gel-like matrix.
- Functions:
- Provides smooth surfaces for joint movement, reducing friction.
- Absorbs shock and distributes weight in load-bearing joints.
- Maintains the shape and flexibility of certain structures (e.g., ear, nose).
- Examples:
- Hyaline Cartilage: Found in joints, trachea, and nasal septum.
- Elastic Cartilage: Found in the ear and epiglottis.
- Fibrocartilage: Found in intervertebral discs and menisci of the knee.
2. Tendons
- About:
- Dense, fibrous connective tissue that connects muscles to bones.
- Composed primarily of collagen fibers, providing tensile strength.
- Functions:
- Transmit forces generated by muscles to bones, enabling movement.
