In this video we discuss what are joints, the types of joints and the functions of joints. We also briefly cover the joint capsule, osteoarthritis and rheumatoid arthritis. Notes What are joints? In the body, a joint is a place where 2 or more bones are joined by soft tissue. If 2 bones meet, it is a simple joint, and if 3 or more bones meet it is a compound joint. Joints have 3 main functions, to join bones together, to bear weight, and to allow the body to move. There are many different ways to classify joints, and in this video we are going to divide them into 3 groups, fibrous, cartilaginous, and synovial. Fibrous joints allow very little movement, and are attached by dense fibrous connective tissue. The connection between the radius and ulna bones in the forearm is an example of a fibrous joint. Cartilaginous joints are joints where bones are connected by cartilaginous tissue, which allows for a limited amount of movement. The discs located in the spine are an example of cartilaginous joints. Synovial joints are the most complicated joints in the body, and they are the types of joints that most people think of when they think about joints. Synovial joints allow for a great deal of movement, and the bones of a synovial joint are connected by a joint capsule, such as the shoulder, knee, and elbow joints. The joint capsule has an outer fibrous layer, and an inner synovial membrane layer. The synovial membrane layer secretes synovial fluid, which reduces friction between the articular cartilage of the bones during physical movement, aides in shock absorption, and aides in nutrient and waste transportation. Ligaments and tendons surround many joints, and they help stabilize the joint and they help protect joints and bones by absorbing some of the shock as the body moves. Some common joint injuries include ligament or tendon tears, which limits the range of motion of the joint, this is many times caused by overuse, or over extension of the joint. Meniscal tears in the knee joint usually caused by wear and tear over time, and damage to articular cartilage that covers the ends of bones, usually caused by a falling directly onto a joint.

Arthritis is the most common joint disease, and there are over 100 different forms of arthritis with osteoarthritis and rheumatoid arthritis being the most common. Osteoarthritis is when there is a reduction in the amount of cartilage tissue of the joint usually resulting in bones rubbing on bones and can be brought on by regular wear and tear or injury to the joint. Rheumatoid arthritis is a disorder where the immune system attacks body tissues. How to maintain or improve joint health. Things you can do to maintain and improve joint health include maintaining a healthy weight, which will put less stress on joints, eat plenty of nutrient dense foods like fruits, veggies and whole grains, and healthy fats. Drink plenty of water which can help joints stay lubricated. Stay active, stretch regularly putting joints through their range of motion, avoid injury and the same repetitive movements. And that be the basics on joints
