Editing Inner ear (section)

===Equilibrium===
The inner ear is primarily responsible for balance, equilibrium and orientation in three-dimensional space. The inner ear can detect both static and dynamic equilibrium. Three [[semicircular ducts]] and two chambers, which contain the [[saccule]] and [[utricle (ear)|utricle]], enable the body to detect any deviation from equilibrium. The macula sacculi detects vertical acceleration while the [[macula utriculi]] is responsible for horizontal acceleration. These microscopic structures possess stereocilia and one kinocilium which are located within the gelatinous otolithic membrane. The membrane is further weighted with otoliths. Movement of the stereocilia and kinocilium enable the hair cells of the saccula and utricle to detect motion. The semicircular ducts are responsible for detecting rotational movement.<ref>Anatomy & Physiology The Unity of Form and Function. N.p.: McGraw-Hill College, 2011. Print.</ref>
