24. The human body loses its balance when what happens?

The base of support is not directly over the center of mass.
The base of support is narrow
The center of mass falls outside of its base of support
When a load is held outside of the base of support
25. When a client has poor motor control it increases his/her risk of joint pain and injury because of what two reasons?

Poor motor control puts less stress on the muscles and joints
Poor motor control impairs the smoothness and accuracy of movement
Poor motor control increases the speed and timing of movement
Poor motor control puts more stress on the muscles and joints
26. Which system contains structures and neurons that connect receptors within the skin, muscles, and joints to the cerebellum?

Somatosensory system
Visual system
Vestibular system
Balance system
27. After months of practicing a movement, an athlete is able to "automatically" produce that movement very quickly. This is due to the development of:

Closed-loop motor control
Neuroplasticity
Open-loop motor control
Sensory feedback
28. The process that underlies all motor learning is known as:

Neuroplasticity
Long-term potentiation
Open-loop motor control
Reflex actions
29. Which brain structure is primarily responsible for correcting movement while it's occurring?

Cerebral cortex
Motor cortex
Cerebellum
Brainstem
30. What is the primary difference between closed-loop and open-loop motor control?

Open-loop motor control occurs more slowly
Open-loop motor control uses sensory feedback to learn a movement
Closed-loop motor control occurs more quickly
Closed-loop motor control uses sensory feedback to learn a movement
