Study Notes
Joint Types
- Joints are the meeting point of two or more bones.
- Three main types of joints exist: fibrous, cartilaginous, and synovial.
Fibrous Joints
- Sutures: Found in the skull, bones joined by fibrous tissue.
- Gomphosis: Example is teeth in sockets, held in place by periodontal ligaments.
- Syndesmosis: Inferior tibiofibular joint, bones connected by ligaments.
Cartilaginous Joints
- Two types exist: primary and secondary.
Primary Cartilaginous Joint
- Temporary joint, ossifies (becomes bone) during adulthood.
- Located at the ends of long bones.
- Composed of hyaline cartilage.
- Connects epiphysis and diaphysis.
Secondary Cartilaginous Joint
- Permanent and slightly moveable.
- Located between vertebrae (intervertebral discs).
Synovial Joints
- Freely movable.
- Strong fibrous capsule surrounds the joint.
- Synovial membrane lines the fibrous capsule and secretes synovial fluid.
- The fluid lubricates and nourishes articular cartilage.
- Ligaments support and strengthen the joint.
- Intra-articular structures, like articular fibrocartilaginous discs, are found within synovial joint cavities.
Types of Synovial Joints (Based on Movement Axis)
-
Uni-axial: Movement occurs around a single axis.
- Hinge joints (elbow, knee)
- Pivot joints (superior radioulnar joint)
-
Bi-axial: Movement occurs around two axes.
- Condylar joints (temporomandibular joint, knee)
- Ellipsoid joints (wrist)
- Saddle joints (carpometacarpal joint of the thumb)
-
Multi-axial: Movement occurs around three axes.
- Ball and socket joints (shoulder and hip)
-
Non-axial: Movement occurs along a gliding/plane, little rotation.
- Plane joints (superior tibiofibular joint)
Example Joint Types with Specific Locations
- Examples of fibrous joints: Sutures (skull), gomphoses (teeth), and syndesmoses (inferior tibiofibular joint).
- Examples of primary cartilaginous joints: Synchondroses (between the epiphysis and diaphysis of long bones)
- Examples of secondary cartilaginous joints: Symphyses (intervertebral discs)
- Examples of uni-axial joints: Hinge (elbow) and pivot (superior radioulnar) joints.
- Examples of bi-axial joints: Condylar (temporomandibular, knee), ellipsoid (wrist) and saddle (carpometacarpal) joints
- Examples of multi-axial joints: ball-and-socket (shoulder and hip) joints.
- Example of non-axial joint: Plane (superior tibiofibular) joints.
