Head Movement Semicircular Canals Hair Endolymph Process Vestibular

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
