Protects organs and attaches muscles 1 of 44 Name an example of a flat bone Ribs, cranium 2 of 44 What is the role of a long bone? Levers for movement and produce red blood cells 3 of 44 Name an example of a long bone Femur, phlanges 4 of 44 Where would you find an irregular bone and what are they for? Vertebrae, protecting the spinal chord 5 of 44 What is the role of a short bone? Bear weight 6 of 44 Name an example of a short bone Carpals and tarsals 7 of 44 What is the role of a sesamoid bone? Ease joint movement and resist compression 8 of 44 Where would you find a sesamoid bone? Patella 9 of 44 Name the 5 things found in a synovial joint Ligament, articular cartilage, synovial fluid, joint capsule and bursa 10 of 44 What is a ligament? Connects bone to bone and stabalises joints 11 of 44 What is an articular cartilage? Smooth tissue at the surface of bones which absorb shock and prevent friction 12 of 44 Why is synovial fluid important? Reduces friction and nourishes cartilage 13 of 44 What is the role of a joint capsule? Encloses and strengthens joint, produces synovial fluid 14 of 44 What is a bursa? Fluid filled sack which reduces friction between tendons and bones 15 of 44 Name 5 types of joint Hinge, pivot, gliding, ball and socket and condyloid 16 of 44 What is a hinge joint? Limited sideways movement found at the knee or elbow - flexion and extension 17 of 44 What is a gliding joint? Flat bones with limited movement eg. spine 18 of 44 What is a ball and socket joint? Joint with large range of movement in all 3 planes eg. hip 19 of 44 What is a condyloid joint? Flat bones with movement in 2 planes eg. wrist joint 20 of 44 What is a pivot joint? Round bone articulating a ring bone eg. radio-ulna 21 of 44 What is a frontal plane? Divides body into anterior and posterior 22 of 44 What movement is involved in a frontal plane? Aduction and abduction 23 of 44 Give an example of a frontal plane movement Star jump 24 of 44 What is a sagittal plane? Divides body into left and right 25 of 44 What movement is involved in a sagittal plane? Flexion, extension, dorsi flexion and plantar flexion 26 of 44 Give an example of a sagittal plane movement Bicep curl 27 of 44 What is a transverse plane? Divides body into upper and lower 28 of 44 What movement is involved in a transverse plane? Horizontal extension, horizontal flexion, rotation 29 of 44 Give an example of a transverse plane movement Discus throw 30 of 44 Explain flexion Decreasing the angle at a joint 31 of 44 Explain extension Increasing the angle at a joint 32 of 44 Explain abduction Moving limb away from centre line 33 of 44 Explain adduction Adding limb to centre line 34 of 44 What is rotation? Rotating around a fixed point eg. neck 35 of 44 What is circumduction? Circling a limb 36 of 44 What is supination? Rotating palm facing up 37 of 44 What is pronation? Rotating palm facing down 38 of 44 What is plantar flexion? Pointing toes down 39 of 44 What is dorsi flexion? Pointing toes up 40 of 44 What is medial rotation? Rotating foot/hand inwards 41 of 44 What is lateral rotation? Rotating foot/hand outwards 42 of 44 What is horizontal flexion? Flexing arm across the body 43 of 44 What is horizontal extension? Flexing arm away from body 44 of 44
