Gliding Motion

Two surfaces slide past each other; movement is slight in various directions.

Angular Motion

Changes the angle between two bones; can be an increase (flexion) or decrease (extension).

Rotation Movement

A specific movement in ball-and-socket joints; allows for multidirectional rotation.

Abduction

Moving a limb or body part away from the midline of the body.

Study Notes

Types of Movement at Synovial Joints

  • Gliding Motion: Involves two opposing articular surfaces sliding past one another; movement is slight in various directions.

  • Angular Motion: Changes the angle between two bones; can be an increase or decrease.

  • Rotation Movement: A specific type of movement found in ball and socket joints, allowing for multidirectional rotation.

  • Abduction: Movement that takes a limb or body part away from the midline; essential for lateral movement.

  • Adduction: Opposite of abduction; involves movement of a limb or part toward the midline.

  • Flexion: A bending motion around a joint that reduces the angle between bones, commonly seen in joints like the knee and elbow.

  • Extension: Straightens a joint and returns a body part to its original position (zero position); crucial for restoring limb posture.

  • Supination: A rotational movement of the hands and forearms where palms face upward; important for grip and certain activities.

  • Pronation: Rotation of the forearm resulting in the palm facing downward; important for various tasks involving the hand.

  • Elevation: Involves raising a body part vertically in the frontal plane; seen in shrugging shoulders.

  • Depression: The opposite of elevation; it lowers a body part vertically in the frontal plane.

  • Protraction: Anterior movement of a body part in the transverse plane, moving it forward and parallel to the ground.

  • Retraction: Posterior movement of a body part in the transverse plane, moving it backward parallel to the ground.

  • Lateral Flexion: Bending of the vertebral column to the side; typically occurs in the spine during bending motions.

  • Dorsiflexion: Involves bending the foot towards the dorsum (upper surface), important for walking and balancing.

  • Plantar Flexion: Movement of the foot away from the dorsum towards the plantar surface (sole); critical for actions like standing on tiptoes.

  • Circumduction: A circular movement at a synovial joint where the distal end of a bone moves in a circle while the proximal end remains stable.

  • Rotation: Involves moving a bone around its longitudinal axis; essential for many body movements, particularly in arms and legs.

  • Opposition: A unique thumb movement that allows it to touch the fingertips; vital for grasping objects.

  • Inversion: A movement that tips the soles of the feet medially to face each other; important for maintaining balance.

  • Eversion: Moves the soles of the feet laterally away from each other; relevant for certain athletic movements and stability.
