Study Notes
Elastic Cartilage Overview
- Elastic cartilage is a type of connective tissue known for its flexibility and elasticity, primarily found in structures requiring shape retention.
Key Terms and Definitions
- Nucleus: Contains DNA and RNA; fundamental for cell growth and reproduction.
- Lacuna: Refers to a small empty space or void within bone or cartilage.
- Chondrocyte: Specialized cell that secretes cartilage matrix and is embedded within it.
- Extracellular Matrix: The non-cellular component in connective tissue, consisting of proteins and other substances that provide structural and biochemical support to surrounding cells.
- Elastic Fibers: Thin, flexible, and stretchable fibers that contribute to the elasticity of tissues.
Functions of Elastic Cartilage
- Supports various body structures while allowing for flexibility and shape retention.
- Protects underlying tissues in areas subjected to bending or deformation.
Locations of Elastic Cartilage
- Found in the external ear, providing shape and flexibility.
- Present in parts of the larynx, important for airway function and sound production.
Structural Characteristics
- Composed of tightly packed elastic fibers interspersed with chondrocytes embedded in a gel-like ground substance, enhancing its resilience and adaptability.
