    Study Notes

    Overview of Cartilage

    • Cartilage is a firm, avascular, non-calcified connective tissue essential for various body functions.
    • It forms a temporary skeleton in the embryo and serves as a model for skeletal bones.
    • Present on articular surfaces of joints, cartilage provides flexibility and smooth movement.

    Importance in Head and Neck

    • The temporomandibular joint (TMJ) is crucial; issues may lead to limited movement and discomfort.
    • Cartilage relies on surrounding connective tissues for nutrients, facilitated by the perichondrium, a fibrous connective tissue sheath.

    Composition of Cartilage

    • Made up of cells (chondroblasts and chondrocytes) and a matrix consisting of fibers and ground substance.
    • Chondroblasts are immature cells that produce the cartilage matrix, while chondrocytes maintain it.
    • The matrix includes proteoglycans, chondronectin, and water, with fibers contributing to cartilage’s strength (40% of dry weight).

    Types of Cartilage

    • Three main types: hyaline, fibrous, and elastic; all initially start as hyaline cartilage.

    Hyaline Cartilage

    • The principal type in fetuses and infants; characterized by small groups of chondrocytes and a smooth matrix.
    • Appears bluish-white and glassy, with limited capacity for repair after injury.
    • Locations include:
      • Articulating surfaces of bones
      • Costal cartilages connecting ribs to the sternum
      • Cartilages of larynx, trachea, and bronchi

    Fibrous Cartilage

    • Dense and tough yet slightly flexible, with chondrocytes separated by thick collagen bundles arranged in parallel.
    • Primarily found in:
      • Intervertebral discs
      • Knee and jaw joints
      • Rim of bony sockets in hip and shoulder joints
      • Pubic symphysis

    Elastic Cartilage

    • Characterized by the presence of elastic fibers within its matrix; this type is the least common.
    • Locations include:
      • Pinna of the ear
      • Epiglottis
      • Part of the tunica media in blood vessel walls

    Summary of Learning Outcomes

    • Understanding the composition and development of cartilage is vital for identifying its types and functions in the human body.
