Abduction/Adduction A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.
What is abduction vs adduction?
Abduction and adduction are terms that refer to certain body motions or movements. With abduction, limbs (arms, legs or fingers) are moved away from your body’s midline. Adduction, however, refers to moving your limbs closer to the midline.
Which term refers to movement of the hand at the wrist away from the midline of the body?
Abduction and adduction Abduction is a motion that pulls a structure or part away from the midline of the body. In the case of fingers and toes, it is spreading the digits apart, away from the centerline of the hand or foot. Abduction of the wrist is also called radial deviation.
What are adduction movements?
Adduction brings the limb or hand toward or across the midline of the body, or brings the fingers or toes together. Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions.
Which joint performs adduction and abduction?
Adduction/abduction and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.
What is away from the midline of the body?
Lateral – away from the midline of the body (example, the little toe is located at the lateral side of the foot).
Is adduction out or in?
So abduction means to keep the legs apart or “away” from each other. Through simple deduction, adduction means the opposite- to draw inward, or closer to the body.
How do you remember the difference between abduction and adduction?
My fool-proof mnemonic trick for differentiating between the two terms is as follows: In the summer, when you want to show off your abs at the beach, you keep your arms as far away from your body as possible because it’s so hot out.
What is abduction anatomy?
In general terms, abduction in the anatomical sense is classified as the motion of a limb or appendage away from the midline of the body. In the case of arm abduction, it is the movement of the arms away from the body within the plane of the torso (sagittal plane).
Is lateral flexion the same as abduction?
Abduction – Movement away from the midline of the body (in the frontal plane). Lateral Flexion – Displacement of the trunk away from the midline in the frontal plane (in the frontal plane).
Which joint performs adduction and abduction horizontal adduction and abduction?
Glenohumeral joint
| Type | Synovial ball and socket joint; multiaxial |
|---|---|
| Blood supply | Anterior and posterior circumflex humeral, circumflex scapular and suprascapular arteries |
| Movements | Flexion, extension, abduction, adduction, external/lateral rotation, internal/medial rotation and circumduction |
Is a movement towards the midline?
Movement towards the midline of the body is called medial (or internal) rotation; movement away from the midline is called lateral (or external) rotation • SUPINATION: turning the palm upwards (or an internal rotation of the foot).
What is abduction and adduction?
Abduction is any movement which pulls the anatomical structure of the body out of the midline. For example, swinging of the body from the side of the body up to the shoulder or higher is abduction. Also, in the hip, abduction is the raising the legs laterally, which move knees away from the midline. Figure 1: Abduction and Adduction
What is the difference between lateral and medial abduction?
When the toes move away from the midline of the foot, toe abduction occurs. Toe adduction adds them right back together. Just like with the hand, devation of the 2nd toe away from the body’s midline is called lateral abduction, whereas movement toward the midline is called medial abduction.

What is the difference between adduction and extension?
Extension refers to a movement that increases the angle between two body parts. For example, abduction of the shoulder raises the arms out to the sides of the body. Adduction is a movement towards the midline. Adduction of the hip squeezes the legs together.
What is the difference between adduction and plane movement?
The movement can occur in a plane, as with a knee flexion, or in multiple planes, such as shoulder movement. Adduction occurs when a joint moves a part of the body toward the midline in a plane. The midline is an imaginary line that runs from the top of the head to between the feet while standing, traveling through the abdominal cavity.
