The lamellae of interstital bone are called interstitial lamellae. 2. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone. Procedure 1. Lacuna. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone. This is why chondrocytes always leave a region around themselves free of the cartilaginous extracellular matrix that makes up the rest of the tissue. Both bone and cartilage use mainly collagen and elastic protein fibers in their extracellular matrix, but cartilage uses a ground substance rich in the carbohydrate hyaluronan and bone uses a ground substance rich in a mineralized calcium phosphate compound known as hydroxyapatite. Today 's Points. Supporting connective tissue comprises bone and cartilage. Fill out the blanks next to your drawing.
