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.
