Study Notes
Functional Classification of Joints
- Functional classification is based on the amount of movement allowed by the joint.
Structural Classification of Joints
- Diarthroses do not represent a structural classification; they signify a functional category.
Types of Joints
- Synarthrosis refers to an immovable joint.
- Synchondroses involve a plate of hyaline cartilage uniting bones, correctly paired in joint classification.
- Epiphyseal plates are classified as cartilaginous joints, crucial during growth.
Joint Prevalence
- Most joints in the body are synovial joints, supporting a wide range of movements.
Joint Stability Factors
- Joint stability is influenced by the shapes of articulating surfaces, muscle tone, and the number and position of ligaments; synovial fluid does not stabilize joints.
Joint Movements
- Extension is categorized as an angular movement.
Joint Types and Examples
- Ball-and-socket joints, such as shoulder and hip, allow multi-directional movement.
- Synovial joints are classified into six main categories based on allowed movements.
Joint-Related Diseases
- Lyme disease, caused by tick bites, is an inflammatory joint disease.
Synovial Fluid Functions
- Synovial fluid lubricates joints and nourishes cartilage but does not strengthen synovial joints.
Hip Joint Stability
- The deep socket of the hip joint significantly contributes to its stability.
Degrees of Joint Movement
- Amphiarthroses allow slight degrees of movement.
Synarthrotic Joints
- Synarthrotic joints permit virtually no movement; found at junctions of growing bones.
Joint Connections
- Syndesmosis is a joint connected by dense fibrocartilaginous tissue allowing slight movement.
- Fibrous joints include sutures, syndesmoses, and gomphoses.
Structural Composition
- The structural classification of joints is determined by the binding material's composition and the joint cavity's presence or absence.
Articular Cartilage Function
- Articular cartilage at the ends of long bones provides a smooth surface at synovial joints.
Symphysis Joint Definition
- A symphysis is a joint united by fibrocartilaginous tissue, allowing limited movement.
