What is the cochlea part of?
What is the cochlea part of?
The cochlea represents the ‘hearing’ part of the inner ear and is situated in the temporal bone. It derives its name from the Greek ‘kokhliās’ (meaning ‘snail’) as it forms a spiral structure during development, which makes it resemble a snail shell.
What is the cochlea?
This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves.
Where in the human body is cochlear?
Inner ear
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus….

What is the visual part of the ear?
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
What’s the main function of cochlea?
The cochlea (auditory inner ear) transforms the sound in neural message. The function of the cochlea is to transform the vibrations of the cochlear liquids and associated structures into a neural signal.
What is another name for the cochlear duct?
The cochlear duct (also known as the scala media) is an endolymph-filled cavity located between the scala vestibuli (upper) and the scala tympani (lower) in the cochlea which is part of the inner ear along with the vestibular apparatus 1,4.
What does the cochlea of the ear look like?
The cochlea is a portion of the inner ear that looks like a snail shell (cochlea is Greek for snail.) The cochlea receives sound in the form of vibrations, which cause the stereocilia to move.
Where are the hair cells located in the cochlea?
The cochlear duct contains endolymph. The scala tympani and cochlear duct are separated by the basilar membrane. Also located within the cochlea are tiny hair cells.
What kind of implant is a cochlear implant?
A cochlear implant (CI) is a surgically implanted neuroprosthetic device that provides a sense of sound to a person with moderate to profound sensorineural hearing loss.
What kind of hearing loss is in the cochlea?
Sensorineural hearing loss is technically defined as hearing loss that arises from any inner ear dysfunction. It includes sensory hearing loss that results from damaged hair cells within the cochlea. Sensorineural hearing loss is extremely common especially in the elderly population but can also be congenital.
