Where two bones meet or link‚ it is called a joint or an articulation. Joints can be classified according to their structure and by the types of movement they allow. The body has more than 300 different joints. In the body there are three types of joints... Moveable/Synovial joints – Moveable joints allow for maximum movement. Moveable or synovial joints are normally found in the limbs‚ as we use these parts more than anything. Ligaments help to provide the stability of the bones‚ also the muscles

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

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

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 shaped head that

Types of joints: Ball-and-socket joint: Consists of a bone with a globular or slightly egg-shaped head that articulates with the cup-shaped cavity of another bone. Such a joint allows a wider range of motion than does any other kind‚ permitting movements in all planes‚ as well as rotational movement around a central axis. The hip and shoulder contain joints of this type. Condyloid joint: The ovoid condyle of one bone fits into the elliptical cavity of another bone‚ as in the joints between the

Hinge joints A hinge joint is the simplest type of joint. It is found in the elbows and the joints of the fingers and toes. Hinge joints allow movement in only one direction. The hinge joint of the knee‚ the body’s largest joint‚ is unusual because it can swivel on its axis‚ allowing the foot to turn from side to side. Therefore‚ the knee is constantly rolling and gliding during walking. Gliding joints Gliding joints are the surfaces that are flat or slightly curved. These joints allow sliding

1 . Describe the Major bones‚ muscles‚joints and joint actions used to perform this movement skill and how they influence the way the body moves. The overarm throw is a skill frequently used in a wide range of sports such as cricket‚softball and baseball. The action is also used in athletic activities such as javelin‚ with the overhead serve and smash in tennis‚ volleyball and badminton and passing a netball and basketball.An overarm throw is the action of the arm swinging backwards then upwards

Pivot joints (known also as rotary joints). These joints allow for rotation around an axis. There is a pivot joint near the top of your spine that allows your head to move from side to side. Hinge joints. This type of joint can open and close like a door. Your elbow is a hinge joint. Your biceps and triceps muscles are basically two people standing on opposite sides of a wall (the humerus‚ or upper-arm bone)‚ each with one hand reaching over to its respective side of a door (the bones of the lower

Joints There are three main joints that are stressed when playing golf. These include the wrist‚ the elbow‚ and the shoulder. Although both the knees‚ as well as the hip‚ are often moved (see pictures 5-8)‚ these joints are not quite as important and no injuries usually occur in these areas. Power is definitely gained from their movement though. Another area that is involved with movement is the trunk. Though technically not a joint‚ it is extremely important in the golf swing‚ and is an area
