Basilar Membrane

Basilar membrane: sound perception of the inner ear

The basilar membrane is an important structure in the cochlea of ​​the inner ear, responsible for converting sound waves into electrical signals that can be processed by the brain. Located between the cochlear duct and the scala tympani, the basilar membrane is a key element in accurately separating the different frequencies of sound waves.

The cochlea of ​​the inner ear is a complex spiral structure consisting of three canals called scalae. The basilar membrane separates the cochlear duct and scala tympani, which are filled with fluid and contain many small hairs called receptor cells.

The spiral organ, or organ of Corti, is located on the basilar membrane inside the cochlear duct. The organ of Corti is made up of more than 15,000 receptor cells, each of which is sensitive to a specific frequency of sound waves. When sound waves enter the cochlea, they cause vibrations in the basilar membrane, which in turn stimulate corresponding receptor cells on the organ of Corti.

Each receptor cell is connected to nerve fibers in the auditory nerve, which transmit electrical impulses to the brain for further processing. Thanks to the precise separation of frequencies on the basilar membrane, the brain can recognize and interpret different sound waves, allowing us to hear and understand the world around us.

In conclusion, the basilar membrane is a critical structure in the cochlea of ​​the inner ear that ensures the precise separation of sound waves into different frequencies. Thanks to this separation, we can hear and understand the different sounds that surround us in everyday life.

The basilar membrane is a thin membrane located in the cochlea of ​​the ear that separates two of the three canals that run along the length of the cochlea. The basilar membrane is an important part of the cochlea and plays an important role in the perception of sound.

The cochlea has three canals called scalae. The middle scala is called the cochlear duct, and the other two are called scala tympani. The spiral organ, which is responsible for the perception of sounds, is located on the basilar membrane, which is located inside the middle scala.

The basilar membrane consists of many hairs that are arranged in a spiral along the entire length of the membrane. These hairs are sensitive to sound waves and transmit sound information to the spiral organ.

In addition, the basilar membrane plays an important role in filtering sounds and highlighting the most important frequencies, which helps us perceive sounds better.

Thus, the basilar membrane is an important component of the cochlea and plays a key role in the perception of sounds.

The basilar membrane or ciliated membrane (lat. Membrana basilaris) is an elastic, oval-shaped membrane consisting of several thousand thin cilia; located on the border between the cochlear duct and the connecting canal (scala vestibuli). Its main function is to separate both staircases in the cochlea
