Structure and movement of joints
Transcript of Structure and movement of joints
Bones are often joined by strong fibres called sutures e.g. the sutures of the cranium Cartilaginous or slightly movable joints Joined by a tough, fibrous cartilage
provides stability and possess shock absorption properties
A small amount of movement still exists, e.g. the articulations between the lumbar bones due to the intervertebral discs of cartilage Synovial or freely movable joints Most common type of joint
greatest range of movement
Enclosed in a fibrous joint capsule, which is lined with a synovial membrane
Lubrication is provided by the synovial fluid, which is secreted by the synovial membrane
lined with smooth yet hard wearing hyaline or articular cartilage TASK:
Using Prezi, you are to design and present a presentation explaining the types of synovial joint (given to you by the tutor), an example of the joint and the movement they provide Task for next week:
read and learn the notes on bone structure via the Prezi link and printed documents on Moodle for next week. There will be a small quiz at the beginning of the lesson. Uniaxial, only allows rotation only
Cervical vertebrae where the axis rotates on the atlas PIVOT SADDLE A biaxial joint where concave and convex surfaces meet
Example: carpo-metacarpal joint of the thumb In your groups, identify examples of each type of synovial joint within the stage of golf swing given to you. You should emphasise the role that each synovial joint plays within this aspect of the swing.
You will present these to your peers. Have questions (3-5) for each group
20 Mins Identify and explain the types of joint in the body
Analyse the role of the synovial joints on performance
Associate the types of movement with the golf swing The movements that occur at joints can be classified according to the action that is occurring between the articulating bones. These are called movement patterns:
Research these movements and analyse their impact on the golf swing.
Place the labels on the image of the golfer. Flexion
Depression Read the following Journal article to assist with relating this topic with golf performance:
