Study Notes
Functional Classifications of Joints
- Diarthrosis refers to highly movable joints, exemplified by synovial joints like the hip joint.
- Bony synostosis joints are the least likely to dislocate due to their rigid structure.
Synovial Fluid and Bursae
- Synovial fluid cushions structures around joints and is found in bursae.
- In bursitis, excessive fluid accumulation leads to joint pain.
- Functions of synovial fluid exclude increasing osmotic pressure within the joint.
Properties of Synovial Joints
- Synovial joints are not covered by a serous membrane, indicating distinct structural characteristics.
Movements and Terminology
- Abduction is the movement away from the midline of the body.
- Pronation involves the radius rolling over the ulna.
- Inversion refers to excessive inward turning of the ankle.
- Opposition is the pinching motion between thumb and finger.
- Flexion typically refers to bending the elbow.
- Hyperextension is an extension past the anatomical position.
Joint Types and Examples
- A saddle joint is illustrated by the trapezium and metacarpal bone of the thumb.
- Carpal bones are classified as gliding joints.
- Pivot joints are monaxial and allow only rotation, while hinge joints, like the elbow, enable bending.
- Ball-and-socket joints provide the greatest mobility, with the shoulder as a prime example.
Foot and Hand Movements
- Plantar flexion enables standing on toes (e.g., ballet).
- Supination involves turning the hand palm up.
- Abduction can be seen when spreading fingers.
- Depression is manifested by opening the mouth.
Knee Joint Stability and Injury
- The elbow’s stability is due to the interlocking of the ulna and humerus.
- Cruciate ligaments maintain tibial and femoral alignment.
- The medial and lateral menisci serve as cushioning in the knee joint.
- Popliteal ligaments reinforce the knee's posterior stability.
- Complete knee dislocations are rare due to its seven major ligaments.
- The medial meniscus is commonly injured in athletic incidents.
- Injuries like a torn lateral collateral ligament affect the femur and fibula junction.
Joint Mobility
- The shoulder joint holds the title for the greatest range of motion in the body.
- The rotator cuff reinforces the shoulder capsule and limits movement.
Arthritis Impact
- Arthritis is characterized by damage to articular cartilages, with varying causes.
