## Question 2.5.4 (2 marks)

The diagram below shows a motor neuron with three structures labelled P, Q and R. Write down the letters P, Q and R in the order in which a nerve impulse travels through this neuron.

Figure: A nerve cell drawn from left to right. At the left, R marks the short branching fibres that spread out from the cell body. P marks the round cell body with its nucleus. A long fibre with a series of white sheath segments runs to the right and ends in branching tips, marked Q, next to a muscle.
