Expert Solution

Step 1

The motion of the body is sensed by the vestibular labyrinth (ears) and eyes. The visual signals are sent to the occipital cortex of the cerebrum. The frontal and parietal cortex regulates eye movements to target the visual system during head and environment movements. The sensation of the center of gravity and maintenance of static equilibrium is done by macula in utricle and saccule. The dynamic equilibrium is maintained by crista in the ampulla of the semicircular canal. The posture and balance of the body are maintained by muscles, joints and controlled by the cerebellum.
