utriclen
The utricle is one of the two otolith organs in the vestibular labyrinth of the inner ear. It is a small, sac-like structure located in the vestibule, a central cavity of the bony labyrinth, between the cochlea and the semicircular canals. Along with the saccule, it is responsible for detecting linear acceleration and the force of gravity.
The sensory epithelium of the utricle is called the macula utriculi. This macula contains sensory hair cells,
The otolithic membrane is covered with small calcium carbonate crystals known as otoliths or statoconia. When
The bending of the stereocilia towards the kinocilium depolarizes the hair cell, increasing the release of
