2. Figure 1 Vertebrate and invertebrate ears.
While the anatomy between vertebrate and invertebrate auditory organs is very different, the molecular modules in hair cells and auditory neurons in the fly consist of a transduction channel, a gating spring and adaptation motors. (A–D) The Drosophila ear. (A) The arista together with the third antennal segment function as the receiver [20]. (B) Two opposing populations of sensory cells in the second antennal segment are activated by stretch. (C) Chordotonal neurons are the sensory cells in the fly's ear. The site of transduction is most likely a part of the sensory cilium. (D) Molecular architecture of a transduction module. (E–H) The mammalian ear. (E) The tympanum is the primary receiver in the mammalian ear. Sound is transduced via the ossicles to the cochlea that contains the organ of Corti. (F) Organ of Corti contains the sensory cells — the hair cells. (G) Hair cell: the actin filled stereocilia form the hair bundle the sensory organelle. (H) Molecular architecture of a transduction module. Part (A) with permission from [20].
