kuuloaivokuorelle

Kuuloaivokuorelle, also known as the cochlea, is a spiral-shaped structure located within the inner ear. It plays a crucial role in the sense of hearing by converting sound vibrations into electrical signals that the brain can interpret. The cochlea is composed of three main parts: the scala vestibuli, scala media, and scala tympani. The scala media contains the organ of Corti, which houses the hair cells that are essential for sound detection. Sound waves enter the cochlea through the oval window and travel through the perilymph fluid, causing the basilar membrane to vibrate. These vibrations are then transmitted to the hair cells, which convert the mechanical energy into electrical impulses that are sent to the brain via the auditory nerve. The cochlea's unique structure allows it to distinguish different frequencies of sound, enabling humans to perceive a wide range of sounds and tones. Damage to the cochlea can lead to hearing loss, and conditions such as otosclerosis, Meniere's disease, and acoustic neuroma can affect its function.
