| The maculae consist of rather shapeless compartments known as the sacculus and utriculus. |
| Ultrasonography is used for the diagnosis and follow-up of the progression of the uterine sacculus until its disappearance. |
| The neuromasts in the sacculus are apparently oriented oppositely from those in the utriculus. |
| The mechanism seems to be that noise energy is transmitted from the stapes footplate into the vestibular part of the labyrinth, especially to the sacculus and the utriculus. |
| Sacculus formation is common, but rupture of a sacculus is very rare. |
| This was accomplished by the evolution of a sacculus surrounding the cell. |
