  • The utricle detects linear accelerations and head-tilts in the horizontal plane. (wikipedia.org)
Occur1
  • Hydrops in the utricle may occur less frequently because of a thicker wall, because of a functioning UEV, and when the saccule has already occupied most of the vestibular perilymphatic space. (bvsalud.org)
Ears2

Head2
  • The utricle contains mechanoreceptors called hair cells that distinguish between degrees of tilting of the head, thanks to their apical stereocilia set-up. (wikipedia.org)
  • Hair follicles in the saccule and utricle add to the balance information by providing feedback about the position of the head in reference to gravity (vertical orientation) as well as detecting linear motion of the head. (revitalhealth.ca)
