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.
