Anatomical Movements: Abduction and Adduction

This video tutorial by Ben from registerednessrn.com explains the concepts of abduction and adduction, which are angular body movements involving structures moving toward or away from a midline reference point. The video covers the differences between these movements and flexion and extension, highlighting that abduction and adduction primarily occur in the frontal or coronal plane. The tutorial provides examples of these movements in various body parts, including arms, fingers, thumbs, wrists, thighs, and toes. It also discusses radial and ulnar deviations of the wrist. The video concludes with a call to action for viewers to take a quiz and explore additional anatomy resources.

Which plane do abduction and adduction movements primarily occur in?

• Frontal or coronal plane

• Sagittal plane

• Oblique plane

• Transverse plane

What does the term 'abduction' refer to in anatomical movements?

• Movement away from the midline

• Rotation around an axis

• Movement toward the midline

• Flexion of a joint

During arm abduction, in which direction do the arms move?

• Parallel to the body's midline

• Perpendicular to the body's midline

• Away from the body's midline

• Toward the body's midline

What is the movement called when fingers move back toward the hand's midline?

• Finger abduction

• Finger adduction

• Finger extension

• Finger flexion

How does the thumb's movement differ from other fingers during abduction?

• It moves in the transverse plane

• It moves in the sagittal plane

• It moves in the coronal plane

• It does not move

What is radial deviation of the wrist?

• Movement toward the body's midline

• Movement away from the body's midline

• Movement toward the radial side

• Movement toward the ulnar side

What is the anatomical position helpful for determining?

• Abduction and adduction

• Flexion and extension

• Rotation and circumduction

• Pronation and supination

During thigh abduction, where does the lower limb move?

• Toward the body's midline

• Perpendicular to the body's midline

• Away from the body's midline

• Parallel to the body's midline

What is the midline reference point for the foot?

• The second toe

• The little toe

• The big toe

• The third toe

What is lateral abduction of the second toe?

• Movement away from the body's midline

• Movement perpendicular to the body's midline

• Movement parallel to the body's midline

• Movement toward the body's midline
