  • What is cartilage?

    Cartilage is a resilient and smooth elastic tissue that acts as a rubber-like padding covering and protecting the ends of long bones, nose, bronchial tubes, and intervertebral discs.

  • What is the function of elastic cartilage?

    Elastic cartilage maintains the shape of a structure while allowing great flexibility.

  • Where is elastic cartilage located?

    Elastic cartilage is found in the external ear (auricle) and epiglottis.

  • Describe the structure of elastic cartilage.

    Elastic cartilage is similar to hyaline cartilage but contains more elastic fibers.

  • What is the structure of hyaline cartilage?

    Hyaline cartilage has an amorphous but firm matrix with collagen fibers forming an imperceptible network; chondrocytes are located in lacunae.

  • What functions does hyaline cartilage serve?

    Hyaline cartilage supports and reinforces, serves as a resilient cushion, and resists compressive stress.

  • Where is hyaline cartilage found?

    Hyaline cartilage is located in the embryonic skeleton, ends of long bones, costal cartilages, nose, trachea, and larynx.

  • How does fibrocartilage differ in structure from hyaline cartilage?

    Fibrocartilage has a matrix similar to but less firm than hyaline cartilage, with thick collagen fibers predominating.

  • What is the function of fibrocartilage?

    Fibrocartilage provides tensile strength allowing it to absorb compressive shock.

  • Where is fibrocartilage located?

    Fibrocartilage is found in intervertebral discs, pubic symphysis, and menisci of the knee.
