All sensory hair cells of the inner ear exist in extracellular fluid, but in some areas the fluid has the characteristics of intracellular fluid, as far as concentrations of K + and Na + are concerned. The membranous labyrinth contains the intracellular fluid-like endolymph, and is surrounded ...
Inner Ear a membranous labyrinth; main part of the organs of hearing and equilibrium in vertebrates and man. The inner ear is filled with a fluid—endolymph—and embedded in the cartilaginous or bony skeletal labyrinth. The slitlike cavity between the inner ear and skeletal labyrinth is filled...
Related to inner ear:middle ear,Inner ear infection inner ear n. The portion of the ear located within the temporal bone that is involved in both hearing and balance and includes the semicircular canals, vestibule, and cochlea. Also calledinternal ear,labyrinth. ...
Its small size coupled with its inaccessibility presents unique challenges for drug delivery. In addition, the sensitive and complex inner ear structures are important considerations for drug delivery systems development. The cochlea is a bony spiral filled with three fluid spaces that continue Catheter...
Inner Ear Theinner earis a fluid-filled cavity situated deep within thetemporal boneof the skull. It consists of two functional components—thecochlea, which is part of theauditory system, and thelabyrinth, which contains thesemicircular canalsand is part of thevestibular system(seeFig. 7.21). ...
An inner ear catheter has a distal end in vibratory communication with the fluid of the inner ear, a proximal end in vibratory communication with the acoustic transducer, and a lumen filled with a catheter fluid for coupling vibratory signals between the distal end and the proximal end....
The fluid mechanics of the inner-ear disorder BPPV The inner ear of mammals contains fluid-filled semi-circular canals with a flexible sensory membrane (called a cupula) which detects rotational acceleration. Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common disorders... M ...
Acute otitis media (AOM): The infection and inflammation of the middle ear4 Otitis media with effusion (OME): AOM with the buildup of noninfected fluid in the middle ear5 Chronic suppurative otitis media (CSOM): An ongoing inner ear infection with persistent drainage lasting for more than tw...
Your inner ear is a labyrinthof fluid-filled tubes and sacs. It has three main parts: The cochlea, a shell-shaped structure that sends sound impulses to the brain The semicircular canals, which use your head’s movement to sense your position in space ...
