Any dysfunction of vestibular system leads to various diseases, the most common among them is Benign Paroxysmal Positional Vertigo (BPPV). BPPV is most found in elderly people causing vertigo/dizziness which leads to fall and serious injuries. The primary system in inner ear helping in human body balancing and postural adjustment is the cupula. Cupulolithiasis is a type of BPPV caused when Cupula.

They synapse in vestibular nuclei of the brainstem and in the nodulus or flocculus of the cerebellum. Vestibular nuclei: Four vestibular nuclei are located bilaterally in the medulla oblongata and pons. They receive The cupula is a gel-like membrane that sits over the hair cells that detect the angular acceleration of head movement. Examples of angular head motion includes nodding your head yes, shaking your head no, or tilting your head side to side.

Vestibular System Inner Ear Relationship Balance

THE VESTIBULAR NERVE The inner ear has its own blood and nerve supply. The vestibulocochlear nerve (cranial nerve VIII) travels from the inner ear to the brainstem and is still considered part of the peripheral system until it enters the brainstem. The vestibular nerve has 2 portions: the superior vestibular nerve and the inferior vestibular nerve. Background and objective: The cupula in the ampulla of the semicircular canal, like the tectorial membrane in the cochlea, forms the essential link in transferring endolymph fluid movement stimuli to the hair cells. Clear understanding of physiological cupula movement only started evolving towards the end of the 1970s.

2011-06-02 The vestibular system is a proprioceptive system involved in the detection of head position and movement with respect to gravity.

The vestibulocochlear nerve (cranial nerve VIII) travels from the inner ear to the brainstem and is still considered part of the peripheral system until it enters the brainstem. The vestibular nerve has 2 portions: the superior vestibular nerve and the inferior vestibular nerve. The vestibular apparatus is present in the petrous part of the temporal bone. It consists of a system of membranous tubes and chambers.

An Isolated Semi-intact Preparation of the Mouse Vestibular

These opposing deflections of the cupula affect the vestibular nerve in different ways, which have been demonstrated in experiments involving the labyrinth removed from a cartilaginous fish. The vestibular system monitors the motion and position of the head in space by detecting angular and linear acceleration. The 3 semicircular canals in the inner ear detect angular acceleration and are positioned at near right angles to each other. Each canal is filled with endolymph and has a swelling at the base termed the ampulla.
