Canalithiasis is the most commonly accepted mechanism, wherein the otoliths that detach from the utricle or saccule and floating freely in the endolymph system of the semicircular canals cause neuronal stimulation.
In addition, little is known on tumor affection of the different parts of the vestibular system, as well as a potential relationship between the function of the individual parts of the vestibular system, i.e., the neuroepithelia of the saccule, utricle, and cristae of the semicircular canals.

Ocular VEMPs indicate repositioning of otoconia to the utricle after successful liberatory maneuvers in benign paroxysmal positioning vertigo.
In amphipods, isopods and decapods, where the structure and location of the AG have been analyzed, it was suggested the existence of only one kind of gland, characterized by the presence of thin lines or lobes of compacted cells associated with the subterminal region of the spermatic duct in amphipods, or at the end of each testicular utricle in isopods.

Thus, the cranially located appendix testes and caudally located prostatic utricle are typically the only vestigial structures derived from paramesonephric ducts [14].
And we found that two separate Sox2 expression domains were present at this time, a dorsal domain that corresponds to the sensory primordia of the utricle and a more ventral domain that corresponds to the sensory primordia of the saccule and the prosensory domain of the cochlea.
The sensory organs of the vestibular system are represented by the utricle, the saccule, and the three semicircular canals; they can perceive the gravity vector, the position of the head, and the linear, torsional, and angular accelerations that the head undergoes.
This diagnostic method relies on the fact that the utricle and saccule are not only sensitive to linear acceleration, but also to loud sound.
