Enable gross movements 1 of 27 What is the function of flat bones? Often quite large, protect vital organs 2 of 27 What s the function of short bones? Enable finer, controlled movement 3 of 27 What is the function of irregular bones? Specifically shaped to protect. 4 of 27 What are the articulating bones at the shoulder? Scapula, clavicle, humorous 5 of 27 What are the articulating bones at the elbow? Humorous, radius, ulna 6 of 27 What are the articulating bones at the hip? Pelvis, femur 7 of 27 What are the articulating bones at the knee? Femur, patella, fibula, tibia 8 of 27 What are the articulating bones at the ankle? Tibia, fibulas, talus 9 of 27 What are the six functions of the skeleton? Movement, support, shape and structure, storage of minerals, protection, blood cell reproduction 10 of 27 What is a tendon? Very strong, non-elastic cords that join muscle to bone 11 of 27 What is bursae? A sac filled with liquid, floating inside the joint, to reduce friction between tendon and bone 12 of 27 What is a joint capsule? Tissue that stops synovial fluid from escaping and encloses, supports and holds bones together 13 of 27 What are ligaments? Bands of elastic fibre that attach bone to bone, keeping the joints stable by restricting movement 14 of 27 What is synovial fluid? A clear and slippery liquid that lubricates the joint and stops the bones rubbing together 15 of 27 What is cartilage? A tough byt flexible tissue that acts as a buffer between the bones, preventing bones rubbing together causing friction 16 of 27 What movements can a ball and socket joint perform? Abduction, adduction, flexion, extension and rotation. Most moveable joint in the body 17 of 27 What movements can a hinge joint perform? Flexion, extension, planter-flexion, dorsi-flexion 18 of 27 What bones are at the shoulder joint? Clavicle, humerus, scapula 19 of 27 What are the bones at the elbow joint? Humerus, ulna, radius 20 of 27 What is extension? Increasing the angle at a joint 21 of 27 What is flexion? Decreasing the angle at a joint 22 of 27 What is abduction? Moving a limb away from the midline of the body 23 of 27 What is adduction? Moving a limb towards the midline of the body 24 of 27 What is rotation? A circular movement around a joint or a movement around an axis 25 of 27 What is planter-flexion? A movement at the ankle joint that points the toes and increases the angle at the ankle joint 26 of 27 What is dorsi-flexion? A movement at the ankle joint that flexes the foot upwards and decreases the angle at the ankle joint 27 of 27
