The saccule and utricle, in turn, together make the otolith organs.

A small sac or pouch (especially the smaller chamber of the membranous labyrinth)
The saccule is a bed of sensory cells situated in the inner ear. The saccule translates head movements into neural impulses which the brain can interpret. The saccule is sensitive to linear translations of the head, specifically movements up and down (think about moving on an elevator). ...
An aneurysm or aneurism is a localized, blood-filled balloon-like bulge in the wall of a blood vessel. Aneurysms can occur in any blood vessel, with examples including aneurysms of the Circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta, and abdominal aortic aneurysms. Aneurysms can also occur within the heart itself.
(saccular) Having the form of a series of sacs or pouches; sacculate
(Saccular) From the Latin "sacculus" meaning a small pouch. As for example the alveolar saccules (little air pouches) within the lungs.
A bundle of hair cells that sense changes in pressure.
Sac-like inner ear organ containing otoliths; senses vertical motion of the head.
One of the two fluid-filled sacs in the cochlea separated by the basilar membrane.
