microscopy video, the first image is of a disc between vertebrae.\u00a0 Discs have a different type of connective tissue than bone; <strong>cartilage<\/strong>.\u00a0 Cartilage is found in many firm but flexible structures like your ears or padding between bones.\u00a0 The cells (chondrocytes) have a unique appearance, like there is empty space around them.\u00a0 We'll look at them in closer detail when we cover the respiratory system because cartilage also lines the outside of the trachea (windpipe).<\/p>\n<p style=\"text-align: center;\"><b>Now that you have the basics of bone
