Reissner S Membrane

Reissner's membrane (Reissner S Membrane) is a thin membrane that separates the scala vestibule and the middle scala cochlea duct, located inside the cochlea of ​​the inner ear. This membrane was named after the German anatomist Ernst Reissner, who first described it in 1863.

Reissner's membrane is essential for the functioning of the auditory system. It acts as a barrier between perilymph, the fluid that fills the cochlear duct, and endolymph, the fluid that fills the cavities of the cochlea. This difference in the composition of liquids allows the creation of the electrochemical potential necessary for the functioning of the receptor cells responsible for the perception of sound waves.

In addition, the Reissner membrane tends to vibrate in response to sound waves that pass through the cochlea, resulting in stimulation of receptor cells. This allows us to hear sounds and determine their pitch and volume.

Despite its importance, Reissner's membrane can be damaged by various factors such as injury, infection, or aging. This can lead to impaired hearing function and the development of various diseases such as balance problems or tinnitus.

In conclusion, Reissner's membrane is a key element of the auditory system, playing an important role in transmitting sound waves from the cochlea to the receptor cells and ensuring the normal functioning of the auditory system. Its understanding and study is of great importance for the development of methods of treatment and prevention of hearing disorders.

Reissner's membrane is a thin membrane that separates the scala vestibule (the place where the first stage of sound processing occurs) and the scala mediali (the place where the next stages of sound processing occur). This membrane plays an important role in the functioning of the cochlea, as it protects the scala media from external influences and allows it to function correctly.

The Reissner membrane consists of two layers of tissue: outer and inner. The outer layer is a fibrous tissue that provides strength to the membrane and protects it from damage. The inner layer consists of elastic fabric that allows the membrane to stretch and contract, which is necessary for the transmission of sound waves.

The importance of Reissner's membrane is that it ensures the correct functioning of the cochlea of ​​the inner ear. If the membrane is damaged or missing, sound may travel through the scala, which may cause hearing damage. In addition, the Reissner membrane is also involved in regulating pressure in the cochlea, which is important for proper hearing function.

Some diseases can damage Reissner's membrane. For example, this can occur with diseases of the middle ear, such as otitis media, or with head injuries. In such cases, the membrane may be damaged or missing, which can cause hearing problems and other health problems.

Thus, Reissner's membrane plays an important role in the functioning of the cochlea of ​​the inner ear and is necessary for the proper functioning of hearing. Damage or absence of this membrane can lead to serious consequences for health and quality of life. Therefore, if you notice any changes in your hearing or other ear-related symptoms, it is recommended that you see a doctor for diagnosis and treatment.

Reisner's membrane is a two-layer fold lining the middle layer of the cochlea, along which the acoustic wave reaches the stapes. Despite the insignificant number of cells, the membrane is important in the perception of sounds, since it divides the middle ear into two isolated chambers, between which there is no connection. Otherwise, the eardrum would weaken the vibrations of the middle ear, reducing their sound conductivity to the stapes ossicles

Discovered in 1926 by Irish otolaryngologist Thomas Gillam Reisner.

The thickness of the shell is about 0.2 mm and contains connective tissue that enhances sound transmission. The membrane extends from the base of the cochlea to the anterior part of the middle ear canal, forming a hemispherical apex in front of the auditory axis, which separates the styloid canals at the apex.
