## cochlea_section_nerve.jpg The image is a detailed black-and-white illustration of a cross-section through the inner ear, specifically focusing on the cochlea. The drawing shows various parts labeled with text for educational purposes. At the center of the image is the **cochlea**, which appears as a spiral structure resembling a snail shell. The cochlea is divided into three fluid-filled canals: the **scala vestibuli** (on the left side), the **scala tympani** (on the right side), and the **scala media** (in the center, not labeled in this image but implied by the other two). These canals are separated by membranes. The **vestibular membrane**, which is part of the **scala vestibuli**, is shown with a label. It appears as a thin layer separating the scala vestibuli from the scala media. The **basilar membrane** and the **spiral ligament** are also labeled within the scala media, indicating their positions relative to each other. The **spiral organ (organ of Corti)** is depicted at the base of the cochlea where it connects with the basilar membrane. This structure contains hair cells that are crucial for hearing. The **hair cells**, which are sensory cells, are shown as small protrusions on the basilar membrane. The **stria vascularis** and **Reissner's membrane** (not labeled in this image but implied by the surrounding structures) are also part of the scala media. The **cochlear nerve** is shown extending from the spiral organ into the brain, indicating its role in transmitting auditory information to the brain. The **spiral ganglion**, which contains sensory neurons that connect with the hair cells and send signals along the cochlear nerve, is not explicitly labeled but can be inferred as part of this structure. The image provides a clear view of the intricate anatomy involved in hearing, making it useful for educational purposes.
