The dorsal component forms the utricle and semicircular canals. The cavity of the utricle communicates behind with the semicircular ducts by five orifices. The vestibular system includes the saccule, utricle, and the three semicircular canals. The utricle contains a patch of hair cells and supporting cells called a macula. The macula of the utricle is in a horizontal position and detects horizontal acceleration. Static balance is provided by two ventricles, the utricle and the saccule. The utricle and saccule are the two otolith organs in the vertebrate inner ear. The fruit is a pale cylindrical utricle. The otoliths have two components&colon; the utricle and the saccule. The utricle detects linear accelerations and head-tilts in the horizontal plane. The otolith organs include the utricle and the saccule. In vertebrates, the saccule and utricle together make the "otolith organs". Its cavity does not directly communicate with that of the utricle. Both the utricle and the saccule provide information about acceleration. The fruit is a utricle containing one seed.
