Study Notes
Joint Movements Overview
- Flexion decreases the angle between articulating bones.
- Lateral Flexion moves the trunk left or right along the frontal plane.
- Extension increases the angle between articulating bones, often restoring a body part to its anatomical position.
- Hyperextension continues extension beyond the anatomical position.
Abduction and Adduction
- Abduction moves a bone away from the body's midline.
- Adduction moves a bone toward the body's midline.
Circumduction and Rotation
- Circumduction involves moving the distal end of a body part in a circular motion.
- Rotation revolves a bone around its own longitudinal axis, with variations in lateral and medial rotation.
Movements of Elevation and Depression
- Elevation involves an upward movement of body parts.
- Depression describes a downward movement of body parts.
Protraction and Retraction
- Protraction moves a part of the body anteriorly in the transverse plane.
- Retraction returns a protracted body part to its anatomical position.
Forearm Movements
- Pronation turns the palm of the forearm posteriorly.
- Supination turns the palm of the forearm anteriorly.
Thumb Movements
- Opposition involves thumb movement across the palm to touch fingertips.
- Reposition returns the thumb to its anatomical position.
Foot Movements
- Dorsiflexion bends the foot towards the dorsum or superior surface.
- Plantar Flexion bends the foot towards the plantar or inferior surface.
- Inversion rotates the sole of the foot medially (inward).
- Eversion rotates the sole of the foot laterally (outward).
Specific Joint Movements
- Flexion, extension, and hyperextension of the Atlanto-occipital and cervical intervertebral joints describe movements of the neck.
- Rotation at the Atlanto-axial joint allows head movement.
- Elevation and depression at the temporomandibular joint control jaw movement.
- Flexion and extension describe movements at shoulder and elbow joints.
- Wrist joint movements include flexion, extension, hyperextension, abduction, and adduction.
Metacarpophalangeal Movements
- Abduction and adduction at the metacarpophalangeal joints involve movement of the fingers away from or towards the midline of the hand.
