Unreferenced stub auto yes date December 2009 Expert subject Medicine date November 2008 The otolithic membrane is a gelatinous biological membrane membrane located in the vestibular apparatus of the inner ear , and plays an essential role in the brain s interpretation of equilibrium. Both the saccular macula and utricular macula are covered by an otolithic membrane, thus providing the common name of the otoliths to the Utricle ear utricle and saccule . The membrane is composed of crystalline particles of calcium carbonate called otolith otoliths . When the head is moved the otoliths shift, causing cilia in the nearby saccule and Utricle ear utricle to distort. This produces nerve signals which are sent to the brain, which then uses them to establish its sense of balance. The embedded crystals are very dense and make the density of the otolithic membrane higher than that of the endolymph surrounding it. When the head accelerates along a line or tilts to change its orientation to gravity, the otolithic membrane shifts relative to the bone supporting the maculae. This shift bends the hair cells whose processes are embedded in the otolithic membrane. Category Vestibular system DEFAULTSORT Otolithic Membrane Med stub ... more details
