Fibrous cartilage may be found in such areas as between vertebral discs of the spinal cord. The outer ear, nose, and larynx are some locations of elastic. Hyaline cartilage, also referred to as articular cartilage, covers joint surfaces and additionally may be found in the shoulder and hips as well.Acting as a cushion between joints, cartilage can help distribute the load of pressure and weight over the surface of joints. It also can serve as a shock absorber.ibrous cartilage may be found in such areas as between vertebral discs of the spinal cord. The outer ear, nose, and larynx are some locations of elastic.
