White fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its inflexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains Type I collagen in addition to the normal type II.
Fibrocartilage is found in the soft tissue-to-bone attachments,[1][2]pubic symphysis,[3] the anulus fibrosus of intervertebral discs, menisci, the triangular fibrocartilage and the TMJ.
During labor, relaxin loosens the pubic symphysis to aid in delivery, but this can lead to later joint problems.
Function[edit] RepairIf hyaline cartilage is torn all the way down to the bone, the blood supply from inside the bone is sometimes enough to start some healing inside the lesion. In cases like this, the body will form a scar in the area using a special type of cartilage called fibrocartilage. Fibrocartilage is a tough, dense, and fibrous materia...
