Another type of connective tissue that is also strong but is much more flexible is known as cartilage. And that's exactly why cartilage is found in those regions of our body that require a greater degree of flexibility, such as, for example, our nose, our outer ear, our bronchial tubes inside our lungs, our ribcage, our trachea, the epiglottis, as well as our joints. So on top of discussing cartilage, we're also going to discuss the three types of joints in our body. The fixed joints, also known as the fibrous or removable joints, the synovial joints, as well as our cartilaginous joints. So what exactly is cartilage? Well, cartilage is a type of connective tissue that consists of cells known as contracytes, as well as the extracellular matrix.
