Massage and Bodywork Licensing Examination Kinesiology and Biomechanics 5

Question 1

The Golgi tendon organ (GTO) responds to:

Accepted Answer

Changes in muscle tension or force

Answer

GTOs are tension-sensitive proprioceptors located at the musculotendinous junction that respond to excessive force to protect the muscle and tendon.

Question 2

Which type of muscle contraction occurs when the muscle generates force while lengthening?

Accepted Answer

Eccentric contraction

Answer

Eccentric contraction produces force while the muscle lengthens, common in activities like lowering a weight or walking downhill.

Question 3

Which scapular movement elevates the acromion and is required for full overhead arm reach?

Accepted Answer

Scapular upward rotation

Answer

Scapular upward rotation tilts the glenoid fossa superiorly, allowing full shoulder abduction and flexion above 90 degrees.

Question 4

A 'valgus' deformity at the knee means the tibia deviates:

Accepted Answer

Laterally (away from the midline), creating knock-knees

Answer

Genu valgum (knock-knee) describes lateral deviation of the tibia relative to the femur, so knees angle inward.

Question 5

Which muscle is the primary mover for cervical rotation to the right?

Accepted Answer

Left sternocleidomastoid and right splenius capitis

Answer

Cervical rotation to the right is produced by the left SCM pulling the chin right and the right splenius capitis rotating the head right from behind.
