| 词汇 | utricle |
| 释义 | utricle noun[ C ] anatomy specializeduk /ˈjuː.trɪ.kəl/ us /ˈjuː.trɪ.kəl/ a small bag-like structure in the body, especially part of the inner ear that helps control balance: The semicircular canals, the saccule, and the utricle are the end-organs concerned with the maintenance of bodily equilibrium. The vestibule contains two membranous sacs, the utricle and the saccule, which are in close contact and communicate indirectly. The semicircular canals are sensitive to motion, and a sac called the utricle is sensitive to the pull of gravity. The utricle and saccule are otolithic, or stone-containing, organs. In the male, this portion becomes a small blind pocket, the prostatic utricle, opening into the prostatic urethra.

The fertile fruit is an indehiscent, glabrous utricle c. 1.3 mm long with a thin and semi-translucent wall. In addition to gravity, the saccule and utricle respond to linear head acceleration, while the semicircular canals are stimulated by angular acceleration in the three planes of space. The hollow cylinder section leading from the bifurcation to the utricle is likewise lined with upward-pointing curved hairs.
