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.
