## hair_innervation.jpg The image is a scientific illustration from a book titled "Audiology: Science to Practice" by Kramer & Brown (2019). The figure number is 4-24. It depicts the synapse of afferent and efferent neurons with an inner hair cell (IHC) and an outer hair cell (OHC). The illustration shows two main parts: 1. **Inner Hair Cell (IHC):** - The IHC is on the left side of the image. - It has a large, dark central area that represents the nucleus. - Surrounding this are smaller, lighter areas representing the cytoplasm and organelles. - There are several small, elongated structures extending from the top of the cell. These represent stereocilia, which are hair-like projections involved in detecting sound vibrations. 2. **Outer Hair Cell (OHC):** - The OHC is on the right side of the image. - It also has a large central area that represents the nucleus and smaller areas representing the cytoplasm and organelles. - Similar to the IHC, there are several small, elongated structures extending from the top. These represent stereocilia as well. **Synapse Details:** - **Afferent Neurons (A):** - There are three afferent neurons labeled "A" on both sides of each cell. - They appear to be synapsing with the hair cells, indicating that they transmit signals from the hair cells to other parts of the auditory system. - **Efferent Neurons (E):** - There are two efferent neurons labeled "E" on the IHC and three on the OHC. - These neurons appear to be synapsing with both types of hair cells, suggesting they play a role in modulating the sensitivity of these cells. The illustration is credited to Tatiana Piatanova. The background is white, which helps highlight the details of the cells and their connections.
