Massage Therapist Kinesiology 3 — Questions and Answers
Question 1: What term describes the movement of bringing a limb away from the midline of the body?
- Adduction
- Abduction (Correct answer)
- Circumduction
- Rotation
Correct answer: Abduction
Abduction is movement away from the midline of the body, such as raising the arm laterally.
Question 2: The rotator cuff consists of four muscles. Which of the following is NOT part of the rotator cuff?
- Supraspinatus
- Infraspinatus
- Deltoid (Correct answer)
- Teres minor
Correct answer: Deltoid
The rotator cuff includes the supraspinatus, infraspinatus, teres minor, and subscapularis; the deltoid is not a rotator cuff muscle.
Question 3: Which joint type allows the greatest range of motion in multiple planes?
- Hinge joint
- Pivot joint
- Ball-and-socket joint (Correct answer)
- Saddle joint
Correct answer: Ball-and-socket joint
Ball-and-socket joints, such as the hip and shoulder, allow the greatest range of motion including flexion, extension, abduction, adduction, and rotation.
Question 4: Hyperextension of the lumbar spine primarily involves which muscles?
- Abdominal muscles
- Hip flexors
- Erector spinae (Correct answer)
- Hamstrings
Correct answer: Erector spinae
The erector spinae group extends and hyperextends the lumbar spine by contracting concentrically.
Question 5: When a muscle contracts without changing length and no movement occurs at a joint, this is called:
- Concentric contraction
- Eccentric contraction
- Isometric contraction (Correct answer)
- Isotonic contraction
Correct answer: Isometric contraction
Isometric contraction occurs when muscle tension develops but muscle length and joint angle remain constant, producing no movement.
Question 6: The quadriceps muscle group performs which primary action?
- Knee flexion
- Hip extension
- Knee extension (Correct answer)
- Hip abduction
Correct answer: Knee extension
The quadriceps femoris group (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius) are the primary knee extensors.
Question 7: Which anatomical term describes the front surface of the body?
- Posterior
- Lateral
- Anterior (Correct answer)
- Medial
Correct answer: Anterior
Anterior refers to the front surface or ventral aspect of the body.
