Tympanic duct - Wikipedia
The tympanic duct or scala tympani is one of the perilymph-filled cavities in the inner ear of humans. It is separated from the cochlear duct by the basilar membrane, and it extends from the round window to the helicotrema, where it continues as vestibular duct.
Scala tympani: anatomy and function - Kenhub
Apr 1, 2024 · Of the three canals, the scala tympani is the most inferior canal, located beneath the scala media. Like the scala vestibuli, the scala tympani is a perilymph containing space . The scala tympani connects with the scala vestibuli apically at a small channel called the helicotrema and ends at the round window.
Cochlea: Anatomy, Function, and Treatment - Verywell Health
May 10, 2024 · The cochlea is filled with fluid (perilymph and endolymph) and is divided into three chambers called the scala vestibuli, scala media, and the scala tympani. Two of these fluid-filled chambers sense pressure changes (caused by sound) while the third chamber contains the organ of Corti, the cochlear duct, and the basilar membrane.
Inner ear: Anatomy - Kenhub
Oct 30, 2023 · Because the duct is significantly thinner than the cochlear canal, it divides the canal into two parts: the scala tympani, which is found on the basal part and the scala vestibuli, located on the apical region.
Auditory pathway: Anatomy, ear structures, transduction - Kenhub
Jul 27, 2023 · The scala media lies between the scala vestibuli and the scala tympani and contains endolymph. The spiral organ (of Corti) lies within the scala media. The scala tympani lies below the scala media, and is separated from the scala media by the basilar membrane .
The Inner Ear - Bony Labyrinth - TeachMeAnatomy
Dec 14, 2022 · The inner ear has two openings into the middle ear, both covered by membranes. The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct).
Neuroanatomy, Ear - StatPearls - NCBI Bookshelf
Apr 3, 2023 · The cochlea contains three distinct anatomic compartments: the scala vestibuli, scala media (also referred to as the cochlear duct), and scala tympani. The scala vestibuli and scala tympani both contain perilymph and surround the scala media, which contains endolymph.
Scala tympani - Structure, Function, Diagram - Anatomy.co.uk
Mar 4, 2024 · The scala tympani is one of the three fluid-filled chambers, or scalae, of the cochlea in the inner ear, integral to the process of hearing. The scala tympani is located below the scala media (cochlear duct) and is separated from it by the basilar membrane, a critical component in the auditory transduction process.
13.3: Hearing and Balance - Medicine LibreTexts
Oct 21, 2024 · At the uppermost tip of the cochlea, the scala vestibuli curves over the top of the cochlear duct. The fluid-filled tube, now called the scala tympani, returns to the base of the cochlea, this time traveling under the cochlear duct.
Scala Tympani - Ask An Audiologist
The scala tympani is one of the three fluid-filled chambers of the cochlea, a spiral-shaped structure in the inner ear. It is located below the basilar membrane and contains perilymph, a fluid that is similar to cerebrospinal fluid.
