fibrocartilage fibrocartilage 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. fibrocartilagewhite fibrocartilage from an intervertebral fibrocartilage.symphysis pubis exposed by a coronal section.
