The Vestibular System01:29

The Vestibular System

41.5K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Equilibrium and Balance01:15

Equilibrium and Balance

5.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Vebe Test01:22

Vebe Test

280
The Vebe test is a method used to measure the workability of concrete, particularly effective for dry concrete mixes. This test employs a specific apparatus that includes a cylindrical chamber, a standard slump cone, and a transparent disc-shaped rider, all mounted on a vibrating table. The cylindrical chamber has dimensions of nine and a half inches in diameter and eight inches in height.
To conduct the test, concrete is placed into the slump cone. The concrete is filled in layers and...

    Area of Science:

    • Neurology
    • Otolaryngology
    • Audiology

    Background:

    • Vestibular testing is crucial for diagnosing vertigo, dizziness, unsteadiness, and oscillopsia.
    • Traditional bedside and laboratory assessments form the cornerstone of differential diagnosis for dizziness.

    Purpose of the Study:

    • To introduce core concepts in vestibular assessment.
    • To highlight recent technological advancements in bedside and instrumented vestibular testing.

    Main Methods:

    • Review of current literature and technological developments in vestibular diagnostics.
