Explanation / Answer

1) In Drosophila, the bristle sensory organ is composed of a hollow hair shaft and three cells,

The dendritic tip resides in a high-K+ endolymph. This creates an electric potential of +40 mV. This in turn provides a large (approximately 120 mV) driving voltage into the neuron. Displacement of the shaft compresses the dendritic tip and opens the transduction channels generating action potentials.
