Study Notes
Structural Joints
- Three types: fibrous, cartilaginous, synovial
- Fibrous joints feature dense fibrous connective tissue, limited or no movement, and lack a synovial cavity.
- Cartilaginous joints connect bones through hyaline cartilage or fibrocartilage, allowing slight movement without a synovial cavity.
- Synovial joints have a synovial cavity between bones, permitting a greater range of movement.
Functional Joints
- Three categories: synarthrosis, amphiarthrosis, diarthrosis
- Synarthrosis joints are immovable, such as those found in the skull.
- Amphiarthrosis joints allow slight movement, as seen in intervertebral joints.
- Diarthrosis joints are freely movable, comprising about 90% of the body's joints.
Joint Classifications
- Intervertebral joints are classified structurally as cartilaginous and functionally as amphiarthrosis.
- Sutures are structurally fibrous and functionally classified as synarthrosis.
- The elbow joint is structurally synovial and functionally diarthrosis.
Joint Structures
- The articular capsule encases synovial joints and synovial cavities.
- Synovial fluid serves to lubricate joints, reduce friction, and provide nutrition.
- Articular cartilage covers the ends of bones in a joint, minimizing friction.
- The synovial cavity is a small space that reduces friction between articulating bones.
- The synovial membrane secretes synovial fluid, essential for joint health.
Examples of Joints
- Fibrous joints are present in skull joints, teeth sockets, and the distal tibiofibular joint.
- Cartilaginous joints can be found in intervertebral joints, the pubic symphysis, and between the sternum and manubrium.
- Synovial joints are seen in the shoulder, elbow, hip, and knee, which are the most common types in the human body.
Summary of Functional Joint Locations
- Synarthrosis functional joints are found between skull bones and in teeth sockets.
- Amphiarthrosis functional joints occur in intervertebral joints, tibiofibular joints, and the pubic symphysis.
- Diarthrosis joints are predominant in various areas, comprising the majority of human joints.
