What does utricle mean?
Definition of utricle : any of various small pouches or saccate parts of an animal or plant: such as. a : the part of the membranous labyrinth of the inner ear into which the semicircular canals open. b : a small usually indehiscent one-seeded fruit with thin membranous pericarp.
What does saccule mean?
a little sac
Definition of saccule : a little sac specifically : the smaller chamber of the membranous labyrinth of the ear.
What is a utricle cyst?
Utricle cysts are pear-shaped lesions usually smaller than 10 mm with a simple fluid signal on all modalities unless when complicated by infection or hemorrhage. Müllerian duct cysts are focal failure of regression and saccular dilatation of the embryological müllerian ducts.
What is a prostatic utricle?
The prostatic utricle is an enlarged diverticulum in the posterior urethra, which result from incomplete degradation of the Müllerian ducts or decreased androgenic stimulation of the urogenital sinus [1].
What is an otolith in humans?
The otoliths (ear-stones) are small structures in the inner ear used to register gravity and linear acceleration.
What’s the difference between the utricle and saccule?
Both the utricle and the saccule provide information about acceleration. The difference between them is that the utricle is more sensitive to horizontal acceleration, whereas the saccule is more sensitive to vertical acceleration.
What is an apiece?
Definition of apiece : for each one : individually.
What is utricle urethra?
Prostatic utricle. The prostatic utricle is a small, epithelium-lined diverticulum of the prostatic urethra. It is located in the verumontanum between the two openings of the ejaculatory ducts and extends backward and slightly upward for a very short distance within the medial lobe of the prostate.
What is the utricle in the prostate gland?
Prostatic utricle is a rudimentary structure in the posterior urethra of males. It is an embryological remnant, 4- to 6-mm long opening between two ejaculatory ducts on verumontanum. It denotes the caudal end of fused müllerian duct, conforming to vaginal and cervical portion of the duct [15].
Where is the ejaculatory duct open?
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra above the seminal colliculus.
What’s the difference between saccule and utricle?
What is function of utricle and saccule?
The utricle and saccule are the two otolith organs in the vertebrate inner ear. They are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). They use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation.
How do the utricle and saccule differ from the semicircular canals?
There are two sets of end organs in the inner ear, or labyrinth: the semicircular canals, which respond to rotational movements (angular acceleration); and the utricle and saccule within the vestibule, which respond to changes in the position of the head with respect to gravity (linear acceleration).
How do you spell Hi Jinx?
High jinks, also spelled hi-jinks, is defined in our dictionary as “boisterous or rambunctious carryings-on” or “carefree antics or horseplay,” and if it sounds a bit old-fashioned, that’s because it is. High jinks was in its heyday in the mid-1900s, though it still sees plenty of use today.
What crumby means?
Crumby means “full of crumbs.” Crummy means “lousy.” In British English, crumby and crummy can mean the same thing.
Is it a piece or apiece?
Apiece means each. For example: The movie tickets cost $9.50 apiece. As two words, a piece means per piece, for something that comes in discrete pieces. For example: “We sold cake for $5 a piece” means that we sold each piece of cake for $5.
What plane is the utricle?
sagittal plane
The macule of the utricle is set in the sagittal plane, so it is best placed to detect lateral tilting of the head. The information gathered by the receptors of the saccule and utricle is carried to the hindbrain by the vestibular nerve. The ganglion cells of the vestibular nerve fibers are true bipolar cells.
What is the meaning of the word utricle?
Definition of utricle. : any of various small pouches or saccate parts of an animal or plant: such as. a : the part of the membranous labyrinth of the inner ear into which the semicircular canals open.
What is the urethral utricle?

What is macula utriculi?
A dilated portion of the membranous labyrinth receiving the ampullae of the semicircular canals; contains an area of sensory epithelium, the macula utriculi. 2. Synonym (s): utricle of vestibular labyrinth
How many seeds are in a utricle?
Fruit a perfectly or incompletely 3-celled many-seeded capsule, or a 1-celled 1-seeded utricle. Utricle bursting irregularly, enclosing an oblong longitudinally ribbed seed (or nutlet).
