(a)[3]
Motor neurones and sensory neurones carry out different jobs in nervous coordination. Contrast the structure and function of sensory neurones and motor neurones.
(b)[3]
Using the data in Table 10.1, comment on how: - myelination is related to mean impulse transmission speed; - axon diameter is related to mean impulse transmission speed.
(c)[3]
Fig. 10.1 shows a graph of an action potential in a mammalian neurone. With reference to Fig. 10.1 suggest why: - no additional action potential can occur during A and B. - it is difficult for another action potential to occur during C.
