White fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions; to the former of these constituents it owes its flexibility and toughness, and to the latter its elasticity. Introduction ( Joints or Articulations Sutural ligament Fibrocartilages Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group It is the only type of cartilage that contains type I collagen in addition to the normal type II. Collagen is the main Protein of Connective tissue in Animals and the most abundant protein in Mammals making up about 50% of the whole-body protein
When examined under the microscope it is found to be made up of fibrous connective tissue arranged in bundles, with cartilage cells between the bundles; the cells to a certain extent resemble tendon cells or dense irregular connective tissue, but may be distinguished from them by being surrounded by a concentrically striated area of cartilage matrix, their lacunae, and by being less flattened. A tendon (or sinew) is a tough band of Fibrous connective tissue that usually connects Muscle to Bone and is capable of withstanding tension
Fibrocartilage is found in the pubic symphysis, meniscus, and annulus fibrosus. The pubic symphysis is the midline cartilaginous Joint (secondary cartilaginous uniting the superior rami of the left and right pubic bones. For other uses see Meniscus (anatomy and lens (optics. Meniscus, plural menisci, from the Greek for "crescent" During labor, relaxin loosens the pubic symphesis to aid in delivery, but this can lead to later joint problems. For the Miles Davis album see Relaxin' with the Miles Davis Quintet.
The white fibrocartilages admit of arrangement into four groups—interarticular, connecting, circumferential, and stratiform.
