15.(4 marks) The vestibular system allow us to understand changes in motion. For the following situations please include the specific name of the structures involved and how the structure functions. Diagrams are permitted.a) A dancer is doing a pirouette during a performance - how is his vestibular system detecting this rotational movement?b) A race car driver must stop suddenly to avoid hitting another car – how is her vestibular system detecting this change in velocity?

Using the histograms to the right that depict action potential frequency of each neuron labelled please draw in the missing neurons and the neurotransmitter that would result in this signalling output. Also, name the phenomenon which allows this to occur. 17.
