Discuss the two major classification systems for joints.
Discuss the two major classification systems for joints.
The two major classification systems for joints are structural and functional. The structural classification is based on the material that binds the joints and can be fibrous, cartilaginous, or synovial. The functional classification is based on the degree of movement the joint is capable of and includes synarthroses, amphiarthroses, and diarthroses.
What are the differences between the fibrous, cartilaginous, and synovial joints?
What are the differences between the fibrous, cartilaginous, and synovial joints?
Fibrous joints are connected by fibrous connective tissue, cartilaginous joints are connected by fibrocartilage or hyaline cartilage, and synovial joints connect and articulate within a joint cavity filled with synovial fluid. Synovial joints are diarthroses and provide lubrication and allow free movement between the bones.

Study Notes
Types of Joints and Characteristics
- Interosseus membrane forms syndesmosis between radius and ulna bones
- Gomphosis anchors tooth to socket in jaw
- Cartilaginous joints formed by hyaline or fibrocartilage, with little to no movement
- Synchondroses: connected by hyaline cartilage, permanent or temporary
- Symphyses: connected by fibrocartilage, allowing limited movement
- Synovial joints separated by fluid-filled synovial cavity
- Diarthrotic and freely movable, found in limb joints
- 6 general features: articular cartilage, synovial cavity, articular capsule, synovial fluid, reinforcing ligaments, nerves and blood vessels
- Additional support provided by muscles and tendons across the joint
- Fatty pads provide cushioning and reduce friction within synovial joints
- Articular discs or menisci made of fibrocartilage modify shape of articulating bones
- Different functions of articular discs or menisci depending on the joint
Anatomy and Function of Articular Discs, Bursae, and Tendon Sheaths in Joints
- Articular discs can strongly unite bones in some joints, like between the radius and ulna, or provide shock absorption and cushioning, as in the knee joint.
- Bursae are thin sacs filled with lubricating fluid, located outside synovial joints to reduce friction between adjacent structures like skin, ligaments, muscles, or tendons.
- Subcutaneous bursae are found between the skin and underlying bone, allowing smooth movement, e.g., prepatellar bursa over the kneecap.
- Submuscular bursae prevent muscle rubbing, like the trochanteric bursa at the lateral hip, between the femur and gluteus maximus muscle.
- Subtendinous bursae are located between tendon and bone, providing protection, e.g., subacromial bursa in the shoulder.
- Tendon sheaths, similar to bursae but smaller, contain lubricating fluid, allowing smooth motion of tendons during muscle contraction and joint movements.
- Articular discs and menisci in synovial joints serve various functions, including uniting bones strongly, providing shock absorption, cushioning, and smoothing movements.
- Some synovial joints also have a fat pad, acting as a cushion between bones.
- Bursae are classified by their location and prevent friction between adjacent structures near body joints.
- Bursae are essential in reducing friction between skin, muscles, and tendons, and underlying bones.
- Synovial joints are surrounded by an articular capsule, defining a joint cavity filled with synovial fluid, and are supported by ligaments.
- The knee joint, the largest in the body, is supported by various ligaments, including the tibial and fibular collateral ligaments outside the articular capsule, and the anterior and posterior cruciate ligaments inside the capsule.
