Question
**Correctly Identify the Following Structures of the Cochlea** The provided image is a detailed illustration of the cochlea, a key component of the inner ear responsible for hearing. The cochlea is shown from different views to provide a comprehensive understanding of its anatomy. Below are the structures that need to be identified: 1. **Cochlear Duct**: This is a fluid-filled cavity within the cochlea located between the scala tympani and scala vestibuli, also known as the scala media. 2. **Cochlear Nerve**: This nerve carries auditory information from the cochlea to the brain. 3. **Scala Tympani**: This is one of the three fluid-filled passages in the cochlea, located below the cochlear duct. 4. **Scala Vestibuli**: Another fluid-filled passage in the cochlea, positioned above the cochlear duct. 5. **Vestibular Membrane**: Also called Reissner's membrane, this structure separates the cochlear duct from the scala vestibuli. 6. **Spiral Organ**: Also known as the organ of Corti, it contains hair cells that convert sound vibrations into electrical signals. 7. **Spiral Ganglion**: These neurons transmit auditory information from the hair cells of the cochlea to the brain. 8. **Oval Window**: A membrane-covered opening that leads from the middle ear to the vestibule of the inner ear. Each structure is critical for the process of hearing and contributes to the conversion of sound waves into neural signals that can be interpreted by the brain. Understanding these components is essential for comprehending how the auditory system functions. In the image, these structures are marked with lines pointing to different parts of the cochlea. To correctly identify each part, follow the lines from the boxes labeled on the left to the respective anatomical parts on the right. The image includes cross-sectional and side views of the cochlea to depict these structures accurately.
