    Study Notes

    Types of Joints

    • Synchondroses: Characterized by limited movement, joined by hyaline cartilage.
    • Symphyses: Feature a fibrocartilage disc, allowing small, controlled movement.
    • Synovial Joints: Have a synovial cavity, providing a large range of motion.
    • Hinge Joints: Convex surface fits into a concave surface, allowing movement in one plane.
    • Pivot Joints: Bony pivot within an osteoligamentous ring, allowing uniaxial movement.
    • Ellipsoidal Joints: Oval-shaped projection fits into an oval depression, facilitating flexion, extension, abduction, adduction, and circumduction.
    • Ball-and-Socket Joints: Hemispherical head fits into a cup-like depression, permitting the most flexible movements, including rotation.
    • Fibrous Joints: Two bones connected by fibrous tissue, providing stability.
    • Planar Joints: Characterized by only two articulating surfaces.
    • Complex Joints: Comprise three or more articulating surfaces.
    • Sutures: Found between skull bones, characterized by little or no movement, joined by hyaline cartilage.
    • Synovial Capsule: Encloses the synovial cavity, uniting the articulating bones.

    Joint Movement

    • Uniaxial Movements: Limited to one plane (e.g., flexion and extension).
    • Multiaxial Movements: Include flexion, extension, abduction, adduction, and circumduction in joints like ellipsoidal and ball-and-socket joints.
    • Glenoid Labrum: In some synovial joints, acts as a pad of fibrocartilage between bone surfaces.
    • Ligaments: Help stabilize joints, with some lying outside the articular capsule.

    Specific Joint Examples

    • Ankle Joint:
      • Provides lateral stability: Involves ligaments forming part of the lateral ligament complex.
      • Dorsiflexion Range: Defined movement achieved at the joint.
    • Foot and Ankle Movements:
      • Inversion/Eversion: Achieved through subtalar joint.
      • Supination and Pronation: Specific movements of the foot at joints.
    • Muscles Assisting in Movements:
      • Plantarflexion: Multiple muscles responsible for ankle joint movement and knee flexion.
      • Dorsiflexion: Muscle responsible for lifting the foot and supporting inversion.
      • Toe Flexors: Involved in flexing interphalangeal joints of the toes and assisting in joint movements.
    • Steadying Muscles: Essential for stability and control during movement.

    Additional Joint Features

    • Bursae: Sac-like structures that alleviate friction between joints, located in areas like the shoulder and knee.
    • Articular Cartilage: Covers bone ends in synovial joints, reducing friction through lubrication.
