The bony labyrinth houses the three semicircular canals and the two otolithic organs (the utricle and saccule).
Which part of the brain processes vestibular signals?
The primary processor of vestibular signals is the vestibular nucleus complex that extends from the rostral medulla to the caudal pons. Many signals are sent from the vestibular nucleus to either the thalamus, cortex, or cerebellum that help to process and adjust efferent signals to postural or ocular muscles.
Where is the vestibular sensory organ located?
The vestibular sensory organ is a paired structure located symmetrically on either side of the head within the inner ear. Inside each end organ are the hair cells, the detection units for both linear and angular acceleration. Extending from each hair cell are fine, hairlike cilia; displacement of the cilia alters the electrical potential of the cell. Bending the cilia in one direction causes the cell membrane to depolarize, while hyperpolarization is induced by movement in the opposite direction. Changes in membrane potential induce alteration in the firing of nerve impulses by the afferent neurons supplying each hair cell.
What is the vestibular system?
The vestibular system is a complex set of structures and neural pathways that serves a wide variety of functions that contribute to your sense of proprioception and equilibrium 1). These functions include the sensation of orientation and acceleration of the head in any direction with associated compensation in eye movement and posture.
Which system is compromised of a nexus of peripheral sensory end organs and a complex network of central
The vestibular system is compromised of a nexus of peripheral sensory end organs and a complex network of central neurons. The peripheral anatomy and physiology are grossly responsible for sensing the degree and direction of acceleration, as well as providing a sense of orientation of the head with respect to gravity.
Which system is responsible for the processing of sensory inputs?
The central connections, including most notably the vestibular nuclei, are grossly responsible for processing the numerous sensory inputs. The accurate and ubiquitous perception of movement and self-orientation occurs, in part, because of a healthy vestibular system.
Is the vestibular system a motor system?
On its most basic level, the vestibular system is both a sensory system as well as a motor system. As a sensory system, the vestibular response not only provides an accurate representation of self motion but also is integral in constructing an “internal map” of one’s center of mass in space with respect to gravity.
Where do vestibular nerves come from?
Most of the afferent nerve signals come from the peripheral vestibular system found in the inner ear within the petrous temporal bone. The inner ear contains a bony labyrinth and a membranous labyrinth. The bony labyrinth is filled with a fluid known as “perilymph” which is comparable to cerebrospinal fluid and drains into the subarachnoid space. Suspended within the bony labyrinth is the membranous labyrinth that contains a fluid known as endolymph unique in composition due to its high potassium ion concentration. Endolymph within the membranous labyrinth surrounds the sensory epithelium and interacts with hair cells within the vestibular apparatus to cause nerve transmission.
Where is the vestibular system?
The vestibular system is comprised of several structures and tracts, but the main components of the system are found in the inner ear in a system of interconnected compartments called the vestibular labyrinth.
What is the vestibular system and what does it do?

They also are covered by a gelatinous cap in which are embedded small granular particles ...
What nerves are responsible for taste?
There is no single sensory nerve for taste. The anterior (front) two-thirds of the tongue is supplied by one nerve (the lingual nerve ), the back of the tongue by another (the glossopharyngeal nerve ), and the throat and larynx by certain branches of a third (the vagus nerve ), all of which subserve touch, temperature, and pain sensitivity in the tongue, as well as taste. The gustatory fibres of the anterior tongue leave the lingual nerve to form the chorda tympani, a slender nerve that traverses the eardrum on the way to the brainstem. When the chorda tympani at one ear is cut or damaged (by injury to the eardrum), taste buds begin to disappear and gustatory sensitivity is lost on the anterior two-thirds of the tongue on the same side. The taste fibres from all the sensory nerves from the mouth come together in the medulla oblongata. Here and at all levels of the brain, gustatory fibres run in distinct and separate pathways, lying close to the pathways for other modalities from the tongue and mouth cavity. From the medulla, the gustatory fibres ascend by a pathway to a small cluster of cells in the thalamus and then to a taste-receiving area in the anterior cerebral cortex.

What are the sensory structures of taste?
The sensory structures for taste are the taste buds, clusters of cells contained in goblet-shaped structures called papillae that open by a small pore to the mouth cavity. A single taste bud contains about 50 to 75 slender taste receptor cells, all arranged in a banana-like cluster pointed toward the gustatory pore.
Where are the taste buds located?
Taste buds are located primarily in fungiform (mushroom-shaped), foliate, and circumvallate (walled-around) papillae of the tongue or in adjacent structures of the palate and throat.
What Is Kinesthetic Sense?
