The thoracic cage consists of the 12 thoracic vertebrae, the associated intervertebral discs, 12 pairs of ribs with their costal cartilages, and the sternum. The perichondrium is made up of two differently functioning layers: the inner layer contains chondroblasts (chondrocytes which are not yet fixed within the extracellular matrix, and which continue to produce the components of this thick gel-like substance). As a springy and highly flexible connective tissue, elastic cartilage is found in specific places, primarily in the pinnae (or auricles) of the outer ear, shaping the folds which efficiently channel sound waves towards the inner ear.
