The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea , a part of the auditory system , it constitutes the labyrinth of the inner ear in most mammals .
Research indicates that the vestibular bulbs are more closely related to the clitoris than to the vestibule because of the similarity of the trabecular and erectile tissue within the clitoris and bulbs, and the absence of trabecular tissue in other genital organs, with the erectile tissue's trabecular nature allowing engorgement and expansion during sexual arousal.

The vestibular system is the region of the inner ear where the semicircular canals converge, close to the cochlea. The vestibular system works with the visual system to keep objects in view when the head is moved. Joint and muscle receptors are also important in maintaining balance.
The orifice of the vestibular aqueduct is the hind part of the medial wall; it extends to the posterior surface of the petrous portion of the temporal bone. It transmits a small vein and contains a tubular prolongation of the membranous labyrinth , the endolymphatic duct , which ends in a cul-de-sac between the layers of the dura mater within ...
The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation. The cupula is located within the ampullae of each of the three semicircular canals. Part of the crista ampullaris, the cupula has embedded within it hair cells that have several stereocilia associated with each kinocilium. The ...
The vestibulospinal tract is part of the "extrapyramidal system" of the central nervous system. In human anatomy, the extrapyramidal system is a neural network located in the brain that is part of the motor system involved in the coordination of movement. [2]
The vestibular aqueduct parallels the petrous apex, in contrast to the cochlear aqueduct, which lies perpendicular to the petrous apex. It transmits a small vein , and contains a tubular prolongation of the membranous labyrinth , the ductus endolymphaticus , which ends in a cul-de-sac , the endolymphatic sac , between the layers of the dura ...
The vestibular duct or scala vestibuli is a perilymph-filled cavity inside the cochlea of the inner ear that conducts sound vibrations to the cochlear duct. [ 1 ] It is separated from the cochlear duct by Reissner's membrane and extends from the vestibule of the ear to the helicotrema where it joins the tympanic duct .
