Joints and Movements The Joints Definition: A joint (articulation) is point of contact between bones or between bone and cartilage. Joint Classifications Joints are classified by: The degree of movement they allow The structure of the joint The three types of joints that we will look at are: 1. Fibrous joints 2. Cartilaginous joints 3. Synovial joints Fibrous Joints These joints are also called "fixed" or "immoveable" joints‚ because they do not move. These joints have no joint cavity

Shoulder Joint Anatomy Shoulder joint is a complex multi-dimension joint in the human body‚ also known as the “ball-and-socket”.

Temporomandibular joint (TMJ) is the hinge joint that connects the lower jaw mandible to the temporal bone of the skull ‚ which is immediately in front of the ear on each side of your head . The joints are flexible‚ allowing the jaw to move smoothly up and down and side to side and enabling you to talk‚ chew ‚ and yawn . Muscles attached to surround the jaw joint control the position and movement of the jaw . A treatment method for the temporomandibular joint (TMJ) is aimed to clarif

TMJ is a very unfortunate joint disorder‚ which can cause many different symptoms. TMJ technically stands for temporomandibular joint syndrome. It is also sometimes referred to as a disorder‚ rather than a syndrome. The joints specifically affected by TMJ are critical for your jaw to move‚ and also connect the lower jaw to the skull. While normal‚ everyday aches and pains are common‚ it is not normal to experience chronic pain and suffering. This usually means that there is an underlying problem

be explaining the functions of the different components and types of synovial joints and explain the structure and function of cartilaginous and fixed joints. Most of the joints are synovial and contain synovial fluid which is a lubricating liquid. These are found in the limbs where mobility is important. A synovial joint is also known as a Diarthrosis which are freely movable joints. These types of synovial joints are the largest group with the greatest variations and can be found in the shoulder

Basketball Synovial joint 1 A synovial joint is a joint that allows a wide range of movement. These are important when analysing sporting movement. The first synovial joint that I will look at is the hinge joint. The hinge joint can be found in the knee and elbow. Hinge joint can only perform two types of movement – flexion and extension. When analysing a jump shot we need to get into a set position where our elbow and knees are flexed it is a hinge joint that allows us to do this. When

ASSIGNMENT 2016 Hinge Joint- Knee The knee joint is the largest joint in the body‚ consisting of 4 bones and an extensive network of ligaments and muscles. What is the scientific name of this joint? The knee joints that make up the knee are split into three parts. The femur meets the tibia to form the main knee joint. This joint has an inner called medial and an outer called lateral compartment. The patella joins the femur to form a third joint‚ called the patellofemoral joint. The patella protects

WOODS Is organic and will decay over time. In wetter conditions with decay will be quicker. It is also subject to conditions such as dry rot‚ or pests. The greater the density of wood‚ the greater its mechanical strength. Knots also contained‚ formed where branches grew from main trunk‚ or where a bud was formed. Can generate weaknesses‚ or be aesthetic. HARDWOODS o o Deciduous (leaf-losing) trees. Slower growing‚ making them denser. Some take up to 100 years to reach full maturity

BY JACOB WOODS 12G Synovial Joints Synovial joints are characterised by a layer of synovial fluid surrounding the articulating surfaces. This helps to lubricate the cartilage therefore reducing the friction between the joints. The synovial capsule stores the fluid‚ meaning it can lubricate the joint quickly. There are 5 types of synovial joint. They are as follows. Ball and socket joint Spheroidal joints to give them their technical name are joints that include two articular surfaces; a ball
