  • Cartilaginous tissue

    It is built of intercellular substance (basic) in which protein fibres and cell elements are immersed. Cell elements are cartilaginous cells (chondrocytes) and cartilaginous lacunas that surround them. In case of any mechanical injuries, some chondrocytes metamorphose into chondrogenic cells, and another ones - into chondroclastic cells, which heals the injury.

    Cartilaginous tissue is uninnervated and unvascularized.

    We can divide cartilaginous tissues into following groups:

    Hyaline tissue

  • resistant to attrition
  • builds joints and sternal rib ends
  • forms skeleton in embryonal and fetal periods

    Elastic tissue
  • does not ossify (does not undergo mineralization)
  • forms auricle
  • contributes to part of larynx and epiglottis
    Fibrous tissue
  • built of collagen fibres
  • high resistance to injuries
  • places:
  • spine intervertebral discs
  • places where tendons and bones are joined
