Deiter's cells, also known as Deiters' cells, are a type of supporting cell in the cochlea of the inner ear. They are named after the German anatomist Otto Deiters, who first described them. Here's a step-by-step explanation of their role:

1. Deiters' cells are located in the organ of Corti, which is the sensory organ of hearing. This organ is located within the cochlea, a snail-shaped structure filled with fluid.

2. These cells provide physical support to the hair cells, which are the actual sensory receptors that detect sound vibrations. They help to anchor the hair cells to the basilar membrane, a structure in the cochlea that separates two fluid-filled spaces and plays a key role in the mechanical process that converts sound waves into nerve impulses.

3. Deiters' cells also play a role in maintaining the ionic environment of the cochlea, which is important for the proper functioning of the hair cells.

4. They do not directly transmit vibrations from the tympanic membrane (eardrum) to the incus (an ossicle, or small bone in the middle ear), or from the incus to the cochlea via the oval window. These tasks are performed by the ossicles and the oval window, respectively. The vibrations that reach the cochlea are then detected by the hair cells, with the support of the Deiters' cells.

5. Finally, it's worth noting that Deiters' cells, like other cells in the inner ear, can be damaged by factors such as loud noise, certain medications, and aging. This can contribute to hearing loss.
