Classification of Joints

Three main categories: Synarthroses, Amphiarthroses, Diarthroses (Synovial).
Joints facilitate movement and stability in the skeletal system.

Amphiarthrosis Joints

Slightly movable joints, allowing minimal to moderate motion.
Examples:
- Pubic symphysis
- Intervertebral discs
- Xiphisternal joint

Synarthrosis Joints

Essentially immovable joints; characterized by dense connective tissue.
Examples include:
- Skull bones
- Teeth in the mandible
- Distal tibiofibular joint

Diarthrosis Joints

Freely movable joints, providing a large range of motion; also known as synovial joints.
Key characteristics:
- Supplied with blood.
- May contain discs or peripheral labrum.
- Enclosed in an articular capsule lined with a synovial membrane.
- Contains synovial fluid for lubrication.
Examples:
- Knee
- Hip
- Shoulder

Joint Movement Classifications

Synovial joints classified by movement types:
- Hinge
- Pivot
- Ball and socket
- Ellipsoid/Condyloid
- Planar
- Triaxial
- Saddle

Additional Observations

Diarthroses are often reinforced by ligaments.
Intervertebral joints are classified as amphiarthrosis (symphyses).
The elbow joint is a specific type of diarthrosis (hinge joint).
The axis and atlas in the cervical vertebrae form a diarthrosis joint (pivot joint).
The pubic symphysis serves as an example of an amphiarthrosis joint.
