Study Notes
Joints
- Joints are locations where two or more bones connect.
- Joints provide stability, support movement, and offer protection.
- There are three primary categories of joints: fibrous, cartilaginous, and synovial.
Fibrous Joints
- Also known as synarthrosis joints.
- These joints are non-movable or barely movable.
- Bones in these joints are joined by fibrous tissue.
- Examples include:
- Sutures of the skull
- Inferior tibiofibular joint (syndesmosis)
- Periodontal ligament (gomphoses)
Cartilaginous Joints
- Also known as amphiarthrosis joints.
- These joints are slightly movable.
- Bones in these joints are joined by cartilage.
- There are two types of cartilaginous joints:
- Primary (synchondroses)
- Secondary (symphyses)
Primary Cartilaginous Joints (Synchondroses)
- Bones are connected by a plate or bar of hyaline cartilage.
- Examples include the union between the epiphysis and diaphysis of long bones and the connection between the first rib and manubrium sterni.
Secondary Cartilaginous Joints (Symphyses)
- Bones are united by a plate or bar of fibrocartilage.
- The articular surfaces are covered by a thin layer of hyaline cartilage.
- Examples include:
- Pubic symphysis
- Intervertebral discs
Synovial Joints
- Also known as diarthrosis joints.
- These joints are freely movable.
- The articulating surfaces of bones are covered by hyaline cartilage.
- Bones are further separated by a joint cavity.
- The joint cavity is lined by a synovial membrane.
- The articular surfaces are lubricated by synovial fluid.
- Fluid-filled sacs (bursae) are found in some joints to reduce friction between rubbing structures.
- Synovial fluid is primarily composed of water.
Movements at Synovial Joints
- The number of axes around which movement can occur determines the type of synovial joint.
- Uniaxial joints allow movement around one axis.
- Biaxial joints allow movement around two axes.
- Multiaxial joints allow movement around multiple axes.
Types of Synovial Joints
- Hinge joints (uniaxial)
- Pivot joints (uniaxial)
- Condylar joints (biaxial)
- Plane or gliding (biaxial)
- Saddle joints (biaxial)
- Ball-and-socket joints (multiaxial)
