Study Notes
Joint Classifications
- Amphiarthrosis: A joint allowing only a small amount of movement.
- Diarthrosis: A freely movable joint classified as a synovial joint.
- Functional joint classifications ranked from least to most movable: synarthrosis, amphiarthrosis, diarthrosis.
- Cartilaginous joints classified as synarthroses or amphiarthroses based on mobility.
Structural Joint Classifications
- Fibrous joints: Held together by dense regular collagenous connective tissue.
- Joints classified structurally include sutures, syndesmoses, and gomphoses, all considered fibrous.
- Sutures: A type of synarthrosis found between adjacent bones of the skull.
- Syndesmosis: Example includes the interosseous membrane between the radius and ulna.
Cartilaginous Joints
- Types of cartilaginous joints: symphyses and synchondroses.
- Synchondrosis: Unites bones with hyaline cartilage, exemplified by an epiphyseal plate.
- Symphyses: Unite bones with fibrocartilage and function primarily for protection and shock absorption.
- A herniated disc affects a symphysis joint.
Joint Structure and Function
- Synovial joints: Characterized by a fluid-filled cavity between articulating bones for movement and cushioning.
- Synovial fluid: Lubricates joints, provides nutrients, absorbs shocks, and is crucial for avascular articular cartilage nourishment.
- Tendons connect muscle to bone, while ligaments connect bones together.
- Bursa: A fluid-filled structure protecting long tendons around synovial joints.
Joint Movement Types
- Eversion: Movement where the plantar surface of the foot rotates laterally.
- Flexion and extension of the neck: Used to indicate "yes" through shaking the head.
- Abduction: Movement of a body part away from the midline.
- Uniaxial joints: Allow motion around only one axis.
Truth Statements
- Symphyses do allow movement, contradicting the notion they are functionally classified as synarthroses.
- Both synovial fluid and articular cartilage aid in shock absorption and lubrication in synovial joints.
