1The smaller of the two fluid-filled sacs forming part of the labyrinth of the inner ear (the other being the utriculus). It contains a region of hair cells and otoliths which send signals to the brain concerning the orientation of the head.The maculae consist of rather shapeless compartments known as the sacculus and utriculus....
- A characterization of the ion channels which make a hair cell electrically resonant was obtained via studies of the bullfrog sacculus, a receptor for ground-borne vibration and low-frequency sound.
- Because the sacculus is buried deep within the ear, Todd and his colleagues could not measure its reaction to sound directly.
1.1 another term for saccule.Next to these developing scars, enlarged alveolar sacculi with loss of septae and bronchiolization were observed....
- Sacculus formation is common, but rupture of a sacculus is very rare.
- Ultrasonography is used for the diagnosis and follow-up of the progression of the uterine sacculus until its disappearance.
