What are the vestibular cores?

vestibular nuclei are structures in mammals that are part of the vestibular system that provides the body its sense of balance and awareness of the orientation of the body in space. They are associated with a vestibular nerve that carries sensory data from the ear canals. These structures are located in the brain stem, which is an area at the bottom of the brain associated with the spinal cord. Three of them are the lower vestibular nucleus, the lateral vestibular core and the medial vestibular core, in Medulle Obrongat, the lowest part of the brain stem. The fourth, superb vestibular core, is in the structure immediately above Medulla Oblongata called PONS. It connects to the vestibular system with a vestibular nerve, a branch of a larger vestibulocochlear nerve, which Carries signals from ears to the brain.

The vestibular system is located in the inner ear and consists of two parts, otolites and semicircular channels. Semicircular channels are small passages filled with liquid lined with extremely sensitive hair cells similar to tIm which are used to detect sound. These structures may feel the movement of liquid in semicircular channels caused by rotary movement when the head orientation changes.

Otoles contain small, thick crystals that lie in a less dense gel. When the body is exposed to linear acceleration, the crystals move slightly, which detects hair cells in Otolitch. This information then travels from the inner ear along the vestibular nerves to the vestibular core.

This sensory data helps the body to monitor their own location and movements in three -dimensional space. Therefore, for example, it is possible that people drive in a car or elevator to the sense when it is in motion, even if they see nothing outside. It is also coordinated with the feeling of the body's view to provide a context that helps to interpret visual data, such as determining whether the movement of objects in the field of view of the body is the result of the movement of objects, the organism itself nEbo or orientation on the shift of the head of the body while standing in place.

The functioning of the vestibular core is essential for the body's ability to maintain balance and remain in operation or walking. As a result, damage causes dizziness, nausea and engine management problems due to reduced brain ability to monitor the position and movement of the body. Vestibular cores are also important for vision, because information from the vestibular system, which says the brain, when the head orientation of the head is changed to the object they looked at.
