Example #3: Structural Support
Bones, cartilage, tendons and ligaments provide structural support for your organ systems, enabling you to stand and move.
Bones are dense organs made from connective tissue in the human body. Bones are important in the human body, as they form a rigid frame called the skeleton which gives your body shape. Some bones also offer protection: vertebrae protect the spinal cord; the ribs guard the heart and lungs; the skull shields the brain.
Cartilage is another dense connective tissue, more flexible than bone that serves many purposes. Cartilage fills the gaps between bones and serves as a cushion during movement. Your nose and ears have specialized cartilage-based structures that act like funnels, catching scents and sounds.
Tendons are tough fibrous tissues, primarily made of collagen, that form connections between bones and muscle. Ligaments, which are similar to tendons in composition, connect bone to bone. Tendons and ligaments are capable of withstanding tension and returning to a stable shape, like a rubber band. These supportive structures not only “tape" tissue together, they limit your range of movement preventing you from hyperextending -- stretching muscles too far.
