| Describe the structure of a bone | |
| Describe the microscopic structure of a bone | |
| What is cartilage? | Like bone, it is also connective tissue & contains fibres made of collagen. These fibres are embedded in a complex called chondrin |
| What are the 3 types of cartilage? | 1. Hyaline 2. Elastic 3. Fibrocartilage |

| What is flexion? | Bending, which decreases the angle between articulating bones |
| What is extension? | Straightening, increases the angle between articulating bones |
| What is abduction? | Movement away from the midle of the body |
| What is adduction? | Movement towards the midline of the body |
| What is rotation? | The movement of a bone along its axis e.g. rotation of the humerus |
| What is osteoporosis? | The loss of bone mass which impairs normal functioning. Calcium, vitamin D and excerise all prevent and treat the illness |
