Massage and Bodywork Licensing Examination Kinesiology 2 — Questions and Answers
Question 1: Which muscle is the primary mover during shoulder abduction from 0 to 90 degrees?
- Pectoralis major
- Deltoid (middle fibers) (Correct answer)
- Supraspinatus
- Infraspinatus
Correct answer: Deltoid (middle fibers)
The middle deltoid is the primary abductor of the shoulder from 0 to 90 degrees of movement.
Question 2: What type of joint is the hip joint classified as?
- Hinge joint
- Saddle joint
- Ball-and-socket joint (Correct answer)
- Condyloid joint
Correct answer: Ball-and-socket joint
The hip joint is a ball-and-socket joint, allowing multiaxial movement in all three planes.
Question 3: Which of the following muscles performs knee flexion AND hip extension?
- Rectus femoris
- Biceps femoris (Correct answer)
- Vastus lateralis
- Gracilis
Correct answer: Biceps femoris
The biceps femoris, part of the hamstring group, crosses both the hip and knee, performing hip extension and knee flexion.
Question 4: Pronation of the forearm is primarily performed by which muscle?
- Supinator
- Brachioradialis
- Pronator teres (Correct answer)
- Anconeus
Correct answer: Pronator teres
The pronator teres is the primary muscle responsible for forearm pronation, rotating the palm downward.
Question 5: When a muscle acts as a neutralizer, its role is to:
- Stabilize the origin of the prime mover
- Cancel out an unwanted action of another muscle (Correct answer)
- Assist the agonist in producing movement
- Oppose the action of the agonist
Correct answer: Cancel out an unwanted action of another muscle
A neutralizer (also called a synergist) cancels out an undesired secondary action produced by another muscle.
Question 6: Which plane of movement does shoulder horizontal adduction occur in?
- Sagittal plane
- Frontal (coronal) plane
- Transverse (horizontal) plane (Correct answer)
- Diagonal plane
Correct answer: Transverse (horizontal) plane
Horizontal adduction of the shoulder occurs in the transverse plane, moving the arm across the body parallel to the ground.
Question 7: The Achilles tendon is the common tendon of which two muscles?
- Soleus and peroneus longus
- Gastrocnemius and soleus (Correct answer)
- Tibialis posterior and flexor hallucis longus
- Plantaris and peroneus brevis
Correct answer: Gastrocnemius and soleus
The Achilles (calcaneal) tendon is formed by the union of the gastrocnemius and soleus tendons, inserting on the calcaneus.
