The nasal vestibule is the nostrils, simply lined with an extension of skin epithelium, in contrast to nasal cavity, which is lined with respiratory epithelium; The vestibule of the ear is the central part of the inner ear labyrinth, as used in the vestibular system The vestibulocochlear nerve connects this to the brain
The vestibule is the central part of the bony labyrinth in the inner ear, and is situated medial to the eardrum, behind the cochlea, and in front of the three semicircular canals. [ 1 ] The name comes from the Latin vestibulum , literally an entrance hall.
Human vestibular system of the semicircular canals in the inner ear. 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.
The bony labyrinth, or osseous labyrinth, is the network of passages with bony walls lined with periosteum.The three major parts of the bony labyrinth are the vestibule of the ear, the semicircular canals, and the cochlea.
How sounds make their way from the source to the human brain. In vertebrates, an ear is the organ that enables hearing and (in mammals) body balance using the vestibular system.
The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three semicircular canals via the vestibular ganglion of Scarpa.
The utricle and saccule are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [1] They use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation. The utricle detects linear accelerations and head-tilts in the horizontal plane.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
