Final answer:
The vestibular system can be easily triggered and tested for sensitivity by simulating head movements and changes in position.
Step-by-step explanation:
The vestibular system can be easily triggered and tested for sensitivity by simulating head movements and changes in position. The vestibular system, located in the inner ear, consists of the utricle, saccule, and three semicircular canals. These structures detect linear and angular accelerations and decelerations, which help to maintain balance and spatial orientation.
