- Skeletal system
- injuries
- Joint injuries
- Sprain
- Some of the fibres in a ligament are torn
- Happens when the joint goes through a greater range of movement than normal.
- Some of the fibres in a ligament are torn
- Tennis elbow
- Pain felt on the outside of the elbow
- Caused by poor technique or overuse
- Pain felt on the outside of the elbow
- Golfers elbow
- Pain felt on the inside of the elbow
- Caused by poor technique or overuse
- Pain felt on the inside of the elbow
- Treatment
- Rest Ice Compression Elevation
- Dislocation
- Where a bone at a joint come out of lace
- Needs medical attention to put the bone back in place
- Where a bone at a joint come out of lace
- Torn cartilage
- Small tears appear in the cartilage from forceful twisting / sudden impact
- Sprain
- Fractures
- Stress
- Caused through overuse, lots of small cracks form in the bone
- Greenstick
- Bone bends one side and breaks the other
- Complex
- Multiple breaks
- Simple
- Bone doesnt cause skin to break
- Happen when the force acting on the bone is stronger than the bone itself
- Compound
- Bone causes skin to break
- Treatment
- See a doctor to get it re aligned and get it put in a plaster cat
- Stress
- Joint injuries
- Range of movement at joints
- Rotation
- the bone moves around its own axis in a circular movement
- BIggest range of movement
- the bone moves around its own axis in a circular movement
- Flexion
- The angle at the joint decreases
- Abduction
- Movement of a limb away from the midline of the body
- Adduction
- Moving towards the body
- Extension
- Angle at a joint increases
- Rotation
- Functions of the skeletal system
- Protection
- Protects vital organs
- eg. skull protects brain if you get hit with a hokey stick
- Protects vital organs
- Aid movement
- Bones provide place for muscles to attach - when muscles contract they move bones.
- Bones act as levers allowing body to increase force or speed of the movement
- eg. tennis player with longer levers generates more force on a serve
- Support
- Provides frame
- Protection
- Joints
- Hinge joints
- eg. Elbow and knee
- Flexion and extension
- Ball and socket joints
- eg. Shoulder and hip
- Flexion, extension, adduction, abduction, rotation
- Where two bones meet and where movement can occur
- Hinge joints
- Effect on system through exercise
- Increased bone density
- reduced cance of osteoporosis
- Better posture
- Reduced chance of fractures
- Stronger ligaments and tendons
- Better support of joints, more stability
- Increased production of synovial fluid aids flexibility
- Bone density and diet
- Calcium and vitamin D (absorbs the calcuim)
- Measurement of the mineral content of the bone
- greatert he bone density the stonger the bone
- Increased bone density
- injuries
