Clues

  • *Consists of bones, cartilage, joints & ligaments which accounts for 20% of body mass *Bones fit together to form a framework for the body and are held in place by muscles and ligaments *Skeleton is divided in to 2: 1. Axial skeleton (80 bones) *Skull *V (3, 8)
  • *Fibrous Joints (Fixed) - no movement between bones with a layer of fibrous tissue between them e.g. sutures of the skull *Cartilaginous Joints (slightly moveable) - firmly joined together by cartilage with slightly moveable articulations e.g. pubic symp (6, 14)
  • 1. Diaphysis: *Tubular component or shaft *Constructed by thick collar of compact bone, surrounds a central cavity 2. Epiphysis: *The bone ends *Exterior is made of compact bone, with internal area cancellous (spongy bone) *The epiphyseal line is the j (3, 4, 4, 7)
  • 1. Pectoral Girdle (shoulder): *Upper extremities/limbs (arms and hands) 64 bones, including the shoulder girdle bones 2. Pelvic Girdle (Hip) *Lower extremities/limbs (legs and feet) 62 bones, including the pelvic girdle bones 3. Pectoral and pelvic gird (12, 8)
  • 1. Skull: *28 bones including cranial and facial bones *Hyoid bone 2. Vertebral column *24 single bones - vertebrae *Sacrum - 5 fused bones *Coccyx - 4 fused bones 3. Bony thorax *Sternum *Ribs (24 bones) (5, 8)
