Final answer:
Fibrocartilage is a type of cartilage tissue that is strong due to the presence of collagen fibers. It is found in structures such as intervertebral discs. Fibrocartilage's ECM contains collagens and proteoglycans.
Step-by-step explanation:
Fibrocartilage is a type of cartilage tissue that contains a large amount of collagen fibers, which give the tissue tremendous strength. It is found in structures such as the intervertebral discs in vertebrate animals. Fibrocartilage's extracellular matrix (ECM) consists of collagens, which are the major component of ECM, constituting 25% of all proteins in mammals. Fibrocartilage's ECM also contains other components such as proteoglycans, which help in the compressibility of cartilage in weight-bearing areas.
