Individual chondrocytes reside in small spherical cavities termed lacunae . Chondrocytes are derived from chondroblasts , which are responsible for growth of the cartilage matrix in juvenile tissue. Mature cartilage is typically surrounded by a supporting dense connective tissue or perichondrium . The perichondrium also contains chondroblasts, which maintain the potential to synthesize new cartilage matrix. Chondrocyte nourishment is dependent on diffusion through the cartilage matrix from blood vessels within the perichondrium.
Elastic cartilage is found in the epiglottis, ear lobes, and larynx.
