In this video we look at what is cartilage? We also cover the different types of cartilage in the body, and the functions of cartilage throughout the body. Transcript notes What is cartilage? Cartilage Is a firm connective tissue that is an important structural component in the body. Cartilage is comprised of cartilage cells and matrix. This matrix is a firm gel, that contain cartilage cells and have fibers embedded within it. There are 2 types of cartilage cells, chondroblasts and chondrocytes. Chondroblasts build up cartilage tissue, and once they are mature and are surrounded by the matrix of cartilage, they are called chondrocytes. Cartilage has many important functions in the body. Cartilage caps bones of synovial joints, such as the knee joint, to make movement of the body easier by minimizing friction and help with shock absorption. Cartilage unites the bones of some joints, such as the discs in the vertebral column. It also provides shape to the ear and nose, and supports the trachea. There are 3 types of cartilage, hyaline cartilage, fibrocartilage and elasic cartilage. Hyaline cartilage is the most common type of cartilage and it caps the bones of synovial joints, is found in the nose and in the respiratory passage. Fibrocartilage is the toughest form of cartilage and it is what makes up the discs of the spine and the meniscus in the knee joint. Elastic cartilage provide firmness and elasticity, and it gives shape to the ear and the epiglottis, which acts like a valve, closing when you are eating, blocking any swallowed food from entering your windpipe. Cartilage does not have nerves or blood vessels, so when it gets injured, it does not heal very well. The most common cartilage injuries are to the knee, many times from falling directly onto the knee creating a hole in the articular cartilage that covers the end of the bone, or tearing a meniscus which is usually caused by normal wear and tear over time. Things you can do to maintain and improve cartilage health include maintaining a healthy weight, which will put less stress on joint cartilage, eat plenty of fruits, veggies and whole grains, legumes and healthy fats. Drink plenty of water which can help joints stay lubricated.
