Question 1

The Golgi tendon organ (GTO) responds primarily to:

Accepted Answer

Muscle tension/force and inhibits excessive contraction via autogenic inhibition

Answer

GTOs are located at the muscle-tendon junction and detect tension; when activated, they trigger autogenic inhibition to protect against muscle and tendon damage.

Question 2

Which type of cartilage is found on the articulating surfaces of synovial joints?

Accepted Answer

Hyaline (articular) cartilage

Answer

Hyaline cartilage covers joint surfaces, providing a smooth, low-friction surface for movement and distributing compressive loads across the joint.

Question 3

The iliotibial (IT) band is a thickened fascial band running along the lateral thigh from the iliac crest to:

Accepted Answer

Gerdy's tubercle on the lateral tibia

Answer

The IT band inserts at Gerdy's tubercle on the anterolateral tibia and can become a source of lateral knee pain (IT band syndrome) in runners.

Question 4

The sarcomere is the basic contractile unit of skeletal muscle, and its boundaries are marked by:

Accepted Answer

Two Z discs (or Z lines)

Answer

Sarcomeres span from Z disc to Z disc; actin filaments attach to the Z discs, and myosin filaments occupy the central A band region.

Question 5

Which of the following best describes the function of the erector spinae muscle group?

Accepted Answer

Spinal extension, lateral flexion, and maintenance of upright posture

Answer

The erector spinae runs bilaterally along the spine and is the primary muscle group for extending, laterally flexing, and stabilizing the vertebral column.
