Tectorial membrane
Tectorial Membrane
The Tectorial Membrane (pronunciation: tek-TOR-ee-al MEM-brane) is a structure located within the inner ear, specifically in the cochlea. It plays a crucial role in the process of hearing.
Etymology
The term "Tectorial" is derived from the Latin word "tectorius," which means "covering." This is in reference to the membrane's role in covering the organ of Corti.
Function
The Tectorial Membrane is an integral part of the auditory system. It is positioned directly above the sensory cells of the organ of Corti, and it plays a key role in the conversion of sound waves into electrical signals that can be interpreted by the brain. When sound waves enter the cochlea, they cause the Tectorial Membrane to vibrate. These vibrations are then transferred to the hair cells of the organ of Corti, triggering a series of events that ultimately result in the generation of electrical signals.
