Study Notes
Joint Structures and Functions
- The fibrous capsule is integral to synovial joints, providing protection and stability.
- Bursae, saclike structures, cushion areas between bones and skin, muscles, ligaments, and tendons.
- A sprain refers to the stretching or tearing of ligaments, as seen in injuries involving the iliofemoral ligament.
Joint Movements
- Abduction is represented by panels B and F in anatomical illustrations.
- Flexion occurs when forming a fist, as fingers curl inward.
- Circumduction involves complex movements including rotation, adduction, extension, abduction, and flexion at joints such as the hip.
Types of Synovial Joints
- The radial head and radial notch form a pivot joint, allowing rotational movement.
- The glenohumeral joint exemplifies a ball-and-socket joint, allowing triaxial motion.
- Hinge joints allow uniaxial movements, such as flexion and extension, seen in the knee, elbow, and ankle.
Joint Conditions and Diseases
- Rheumatoid arthritis is the prominent autoimmune condition affecting joints.
- Gouty arthritis results from sodium urate crystal deposits causing joint pain and inflammation.
Joint Treatments
- Arthroplasty surgically replaces joints with artificial constructs for enhanced function.
Anatomical Relationships
- Strength and tension in ligaments affect the range of motion; for instance, in the knee, the posterior cruciate ligament loosens when flexed.
- The anterior cruciate ligament limits hyperextension of the knee.
Structural Classifications
- The maxillae bones fuse completely before birth, forming a synostosis.
- Amphiarthrosis describes the functional classification of intervertebral discs, allowing slight movement.
Non-Synovial Joints
- Syndesmosis and interosseous membranes are types of non-synovial joints providing stability and support.
Hormonal Influences
- Relaxin hormone enhances the range of motion primarily in the pubic symphysis during pregnancy.
Anatomy of Motion
- Opposition is a thumb movement where it comes into contact with fingers, while gliding movements are prevalent in certain joint structures like the tibiofibular ligament.
Movement Characteristics
- The atlanto-axial joint is classified as a pivot joint, facilitating neck rotation.
