utricle (ear)









































the utricle and saccule are the two otolith organs in the vertebrate inner ear. they are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). they use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation. the utricle detects linear accelerations and head-tilts in the horizontal plane. the word utricle comes .

utricle (ear)
the vestibule is a region of the inner ear which contains the saccule and the utricle, each of which contain a macula to detect linear acceleration. the macula of saccule lies in a nearly vertical position. its function is to detect vertical linear acceleration. it is a 2 mm by 3mm patch of hair cells. each hair cell of the macula contains 40 to 70 stereocilia and one true cilia, called a kinocilium. a gelatinous cover called the otolithic membrane envelops the tips of the stereocilia and kinocilium. the otolithic membrane is weighted with small densely packed protein-calcium carbonate granules called statoconica. the macula of the utricle is in a horizontal position and detects horizontal acceleration. the coordinated sensory perception of acceleration both vertically and horizontally along the vestibular nerve, allow for the perception of linear acceleration in any direction.
