Joints and Range of Motion Flashcards
1
Q
Describe joints and their purpose
A
- Formed when bones come into contact
- aka articulations (can be bone to bone or bone to cartilage)
- Hold bones in their proper location
- Provide different degrees of movement between articulated bones
2
Q
What the 3 single articulations?
A
- Hip joint (acetabulofemoral) - pelvis and femur
- Shoulder (glenohumeral) - humerus and scapula
- Pelvis (sacroiliac) - ilium and sacrum
3
Q
What are the 3 multiple articulations?
A
- Knee - femur, tibia, patella and fibula
- Elbow - humerus, radius, ulna
- Ankle - tibia, talus, fibula
4
Q
What is the difference between tendons and ligaments?
A
- Tendons connect muscles to bones, facilitating movement
- Ligaments connect bones to bones, providing stability
5
Q
Describe synovial/diarthrosis joints
A
- Freely movable
- Bones forming the joint are surrounded by articular capsule and accessory ligaments
- Subtypes - hinge, ball and socket, saddle, gliding, pivot and condyloid joint
6
Q
What are active range of movement assessments for?
A
- Performance screening and profiling
- Injury assessment
- Differential testing: muscles and dense connective tissue
7
Q
What are passive range of movement assessments for?
A
- Athletic screening and profiling
- Injury assessments and rehab
- Differential testing - muscles and dense connective tissue
8
Q
What are the 4 types of stretching?
A
- Static
- Dynamic active
- Dynamic ballistic
- PNF
