Fibrocartilage. Fibrocartilage is located in intervertebral disks, pubic symphysis, articular disks, and some tendonous insertions into bone. Note the very fibrous matrix in this type of cartilage (yellow arrows). Unlike hyaline cartilage, this type of cartilage contains type I collagen and contains no perichondrium. The ground substance is much reduced as compared to hyaline and elastic cartilages. The density of lacunae per unit area is reduced in fibrocartilage.
