Skeletal

• Protection


  Protects vital organs, e.g. the cranium protects the brain
• Muscle attachment


  Tendons attach muscle to bone allowing movement .muscles contract to pull the bone to cause movement
• Movement of joints


  Where bones meet they form joints to allow movement. Joints work together with bones and muscles to form levers.
• Storing calcium and phosphorus


  Bone store, calcium and phosphorus minerals that are needed to develop strong bones
• blood cell and platelet production


  Bone marrow makes most of the blood cells, including red, white and platelets
• Tendon


  Non-elastic fibres that attach muscle to bone and help to move them
• Ligament


  Elastic fibres that attach bone to bone and stabilise the joint
• Long bones


  Bones that are longer than they are wide; have a shaft and two ends. . E.g. Femur humorous phalanges
• Short bones


  Only found in the hands/feet and are important for weight-bearing, e.g. carpals and tarsels
• Flat bones


  Protect organs or offer a good surface for muscles to attach to EG ribs cranium scapula sternum patella clavicle
• Irregular bones


  Have odd shapes; some have special takes shape for protection others for muscle attachment e.g. vertebral column sacrum
• Pivot joints, neck


  Atlas and axis flexion and extension
• Hinge knee


  Femur tibia fibula and patella flexion extension
• Hinge elbow


  Humorous radius and ulna flexion extension
• Hinge ankle

  Tibia fibula and talus plantar flexion Dorsi flexion
• Ball and socket shoulder

  Clavicle scapula humorous abduction adduction rotation circumduction flexion extension
• Ball and socket hip

  Pelvis and femur abduction adduction rotation circumduction flexion extension
• Condyloid joint


  Radius ulner and carpals flexion extension abduction adduction
