Endolymph is a clear potassium-rich lymphoid fluid that fills the cavities of the membranous labyrinth in the inner ear. Separated by the Reissner membrane, the membranous labyrinth is surrounded by the sodium-rich perilymph. For hearing, the different ion concentration between perilymph and endolymph plays a major role, while the mechanical-physical properties (principle of inertia) are … Endolymph: Structure, Function & Diseases
Many top athletic performances are characterized by exceptional balance ability. On the other hand, disorders can significantly affect quality of life. What is the ability to balance? The ability to maintain the body in a state of equilibrium or to return to it after a change is called balance ability. The ability to keep the … Balance Ability: Function, Tasks, Role & Diseases
The sense of balance is used to orient in three-dimensional space, to determine the position of the body in space, including the limbs, and to coordinate complex movements. The sense of balance is primarily fed by direct feedback from the paired vestibular organs in the inner ear; in addition, feedback from thousands of proprioceptors in … Sense of Balance: Function, Tasks, Role & Diseases
Meniere’s disease is a complex clinical condition of the inner ear that manifests as attacks of vertigo or spinning vertigo associated with hearing loss, a feeling of pressure in the ear, and ringing or ringing in the ears. About 2.6 million people in Europe and the United States suffer from Meniere’s disease. Learn more about … Meniere’s Disease: Symptoms, Causes, Treatment
Because the cause of Meniere’s disease is unknown, there are many treatments, but no cure. The goal is to reduce symptoms to a tolerable level and achieve improvement as quickly as possible. Doctors prescribe medications to relieve the nausea and vomiting, and IV fluids are also administered to promote blood flow. Meniere’s disease: betahistine reduces … Meniere’s Disease: Treatments
The three paired semicircular canals in the inner ear, equipped with mechanoreceptors, belong to the organs of equilibrium and are each nearly perpendicular to each other, providing one semicircular canal for each of the three main directions of rotation in three-dimensional space. The arcuates are sensitive to rotational accelerations, but not to uniform rotations. They … Archways: Structure, Function & Diseases
