| an adult skeleton is made up of | 206 bones |
| the smallest bones | are found in the ear |
| the largest bone in the human body | is the thigh bone |
| softer than bone (contains less calcium) | cartilage |
| the skeleton | supports, protects, helps us move and makes blood cells |
| scapula | shoulder blade |
| clavicle | collar bone |
| sternum | breastbone |
| cranium | skull |
| humerus | upper arm bone |
| thigh bone | femur |
| knee cap | patella |
| shin bone | tibia |
| toe/ finger bones | phalanges |
| foot bones | metatarsals |
| ankle bones | tarsals |
| backbone is made up of | vertebrae |
| mandible | jaw |
| carpals | wristbones |
| metacarpals | hand bones |
| skeletal muscle | causes movement at joints. We can control. these muscles get tired |
| cardiac muscle | keeps the heart beating. Does not get tired. Involuntary |
| smooth muscle | lines the intestines, blood vessels and airways, it does not get tired |
| skeletal muscles are attached to bones | by tendons |
| ligaments join | bone to bone |
| as one muscle relaxes another contracts | this is antagonistic muscle action |
| biceps and triceps muscles | are good examples of antagonistic pairs |
| the place where bones meet | joints |
| in a fixed joint eg skull | the bones have fused, they cannot move |
| eg of a pivot joint | neck |
| synovial fluid | acts as a lubricant |
| ball and socket joint | shoulder and hip joints |
| hinge joints | elbow and knee joints |
| an artifical limb | prosthesis |
