The ampulla in semicircular canals detect head movement; endolymph pressure on hair cells triggers nerve impulses, and the brain integrates this information from three planes to determine head position.

| Front | process of vestibular system detecting head movement |
|---|---|
| Back | ampula in the semicircular canals are embedded with hair cells; endolymph in semicircular canals follows direction of head movement; endolymph exerts pressure on hair cells, trigger nerve impulses; brain integrates information from 3 planes to identify head position and movement |
