Module 4 – (Movements & Joints) | Portage Learning
Question 1
Which term describes movement away from the body’s midline?
A. Adduction
B. Flexion
C. Extension
D. ✅Abduction
E. Hyperextension
Rationale: Abduction specifically refers to movement away from the midline, such as lifting the
arms laterally.
Question 2
The opposite movement of retraction is elevation.
A. ✅False
B. True
Rationale: The opposite of retraction (posterior movement) is protraction (anterior movement),
not elevation.
Question 3
Which movements are permitted by a saddle joint, such as the thumb’s carpometacarpal joint?
A. Rotation only
B. Gliding only
C. Flexion and extension only
D. ✅Flexion, extension, abduction, and adduction
Rationale: Saddle joints allow biaxial movement but not true rotation.

Question 4
Pointing the toes downward by extending the ankle joint is called:
A. Dorsiflexion
B. Opposition
C. Retraction
D. ✅Plantarflexion
Rationale: Plantarflexion increases the angle between the foot and shin, as when standing on
tiptoes.
Question 5
Damage to the atlantoaxial joint would most directly impair which neck movement?
A. Flexion and extension
B. Abduction and adduction
C. Gliding
D. ✅Rotation
Rationale: The atlantoaxial pivot joint allows rotational movement such as shaking the head
“no.”
Question 6
Which pairing of term and description is correct?
A. Depression – movement forward
B. Elevation – movement downward
C. Protraction – backward movement
D. ✅Reposition – return from opposition
Rationale: Reposition reverses opposition, returning the thumb to anatomical position.
Question 7
Which movements are possible at a ball-and-socket joint? (Select all that apply)
