The ligamentum flava joining the laminae of vertebrae is a type of elastic cartilage. Elastic cartilage is also present in the epiglottis, external ear, and auditory tubes. It is distinguished from other types of cartilage by the presence of elastic fibers in the matrix, in addition to the normal components of hyaline cartilage. As shown in Figure 3.16, a thread‐like network of elastic fibers surrounds chondrocytes in this type of cartilage.

(b) Mid‐power image showing fibrocartilage encircling the nucleus pulposus (the gelatinous interior of intervertebral discs) located in the middle of the disc. (c) High power image showing the presence of chondrocytes within thick collagen fibers in the fibrocartilage.
