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. resistant to attrition
Cartilaginous tissue is uninnervated and unvascularized.
We can divide cartilaginous tissues into following groups:
builds joints and sternal rib ends
forms skeleton in embryonal and fetal periods
does not ossify (does not undergo mineralization)
contributes to part of larynx and epiglottis
built of collagen fibres
high resistance to injuries
spine intervertebral discs
places where tendons and bones are joined
