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 .
This diagram linearly (unless otherwise mentioned) tracks the projections of all known structures that allow for balance and acceleration to their relevant endpoints in the human brain. Another diagram showing neural pathway of vestibular/balance system. Arrows show the direction of information relay.
The primary role of the vestibular system is to maintain head and eye coordination, upright posture and balance, and conscious realization of spatial orientation and motion. The vestibular system is able to respond correctly by recording sensory information from hairs cells in the labyrinth of the inner ear.
This test can provide site-specific information on vestibular system and its function. [ 25 ] Another way of testing the VOR response is a caloric reflex test , which is an attempt to induce nystagmus (compensatory eye movement in the absence of head motion) by pouring cold or warm water into the ear.
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 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.
The intern was going over quantification data in vestibular swabs tied to historical sexual assault cases when he or she noticed specific data was missing, prosecutors said in an affidavit.
The vestibular system is important for balance, or equilibrium. It includes the saccule, utricle , and the three semicircular canals . The vestibule is the name of the fluid-filled, membranous duct that contains these organs of balance and is in turn encased in the temporal bone of the skull as a part of the inner ear.
