## cochlea_unrolled.jpg The image is a diagram illustrating the structure of the cochlea when unrolled into a straight line for clarity. The cochlea is a part of the inner ear that plays an important role in hearing. ### Key Elements: 1. **Base and Apex:** - At one end, labeled as "BASE," you see the base of the cochlea. - At the other end, labeled as "APEX," you find the apex of the cochlea. 2. **Scala Vestibuli (Vestibular Canal):** - This is a canal that runs from the base to the apex and contains perilymph fluid. - It is located on one side of the basilar membrane, which separates it from other parts of the cochlea. 3. **Scala Tympani (Tympanic Canal):** - This canal also runs from the base to the apex but contains endolymph fluid. - It is situated on the opposite side of the basilar membrane compared to Scala Vestibuli. 4. **Basilar Membrane:** - The basilar membrane is a thin, flexible structure that separates the scala vestibuli and scala tympani from each other. - It runs along the length of the cochlea and is crucial for converting sound vibrations into neural signals. 5. **Oval Window (Window of蜗窗):** - Located at the base of the cochlea, this is a small opening that connects the middle ear to the scala vestibuli. - Sound waves from the eardrum travel through the ossicles and cause fluid movement in the scala vestibuli via this window. 6. **Round Window (Window of圆窗):** - Situated at the apex of the cochlea, it is a small opening that connects the scala tympani to the middle ear. - It allows for pressure equalization between the inner and outer ear fluids during sound vibrations. ### Labels: - The diagram includes labels such as "Helicotrema" which marks where Scala Vestibuli and Scala Tympani meet at the apex of the cochlea, forming a small channel that connects these two canals. The image is sourced from Tan et al. (2010), page 46, indicating it's an educational resource for understanding auditory anatomy. This diagram helps in visualizing how sound waves are transmitted and processed within the cochlea to produce neural signals that our brain interprets as sound.
