The vestibular apparatus can be divided into three semi-circular canals and the otolith organ, which is composed of the utriculus and sacculus. |
The maculae consist of rather shapeless compartments known as the sacculus and utriculus. |
The neuromasts in the sacculus are apparently oriented oppositely from those in the utriculus. |
Because the sacculus is buried deep within the ear, Todd and his colleagues could not measure its reaction to sound directly. |
Sacculus formation is common, but rupture of a sacculus is very rare. |
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. |
