What are the 4 types of injury?
Soft, fracture, ligament, tendon
What is a sprain?
Overextension or tearing of a ligament, pain is located at the joint
What is the symptoms of a sprain?
Sweeping, pain and discolouration with impaired motion
What is a strain?
Overextension or tearing of a tendon or muscle
What are symptoms of a strain?
Pain located at the muscle and away from the joints
What is a fracture?
Break or damage to a bone, open or closed
What are the different types of bone fracture?

In what people is colles’ fracture often seen?
In elderly people with osteoporosis
What is a ligament?
A tough band of fibrous tissue that connects bone to bone, or bone to cartilage
What are the functions of ligaments?
- guide forces through adjacent bones or joints
- provide joint proprioception
- provide mechanical feedback
- provide joint stability by limiting excessive range of motion
What is a tendon?
A flexible but inelastic cord of strong fibrous collagen tissue attaching to a muscle to a bone
What is the function of a tendon?
To send mechanical forces of muscle contraction to the skeletal system while withstanding tension
What is elevation?
The movement that raises a bone vertically
What is depression within movement?
Lowering the mandible or the shoulders
