Massage and Bodywork Licensing Examination Kinesiology and Biomechanics 2 — Questions and Answers
Question 1: Which class of lever has the fulcrum located between the effort and the load?
- First-class lever (Correct answer)
- Second-class lever
- Third-class lever
- Fourth-class lever
Correct answer: First-class lever
A first-class lever has the fulcrum (joint) between the effort (muscle) and the load, as seen in head nodding on the atlanto-occipital joint.
Question 2: The gastrocnemius muscle performs which combination of actions?
- Knee flexion and plantar flexion (Correct answer)
- Knee extension and dorsiflexion
- Knee flexion and dorsiflexion
- Knee extension and plantar flexion
Correct answer: Knee flexion and plantar flexion
The gastrocnemius crosses both the knee and ankle, producing knee flexion and plantar flexion.
Question 3: Which term describes a muscle that assists the prime mover by performing the same action?
- Antagonist
- Synergist (Correct answer)
- Fixator
- Neutralizer
Correct answer: Synergist
A synergist assists the agonist (prime mover) in producing the same joint movement.
Question 4: The rotator cuff muscle that performs internal rotation of the glenohumeral joint is the:
- Infraspinatus
- Teres minor
- Subscapularis (Correct answer)
- Supraspinatus
Correct answer: Subscapularis
The subscapularis is the only rotator cuff muscle that internally rotates the shoulder; the others externally rotate.
Question 5: Lateral deviation of the spine is called:
- Kyphosis
- Lordosis
- Scoliosis (Correct answer)
- Spondylosis
Correct answer: Scoliosis
Scoliosis is an abnormal lateral curvature of the spine, often with a rotational component.
Question 6: Which movement decreases the angle between two body segments?
- Extension
- Flexion (Correct answer)
- Abduction
- Circumduction
Correct answer: Flexion
Flexion decreases the angle at a joint, bringing the two segments closer together.
Question 7: The tensor fasciae latae (TFL) primarily assists with which hip movement?
- Hip extension and external rotation
- Hip flexion, abduction, and internal rotation (Correct answer)
- Hip adduction and external rotation
- Hip extension and abduction
Correct answer: Hip flexion, abduction, and internal rotation
The TFL assists with hip flexion, abduction, and internal rotation, and also tenses the iliotibial band.
