Question 1

Figure 1 shows a simplified diagram of a sensory neurone.

A diagram of a sensory neurone. On the far left, there is a receptor cell. A long dendron extends from the receptor to a cell body that is positioned on a side-branch. From this junction, an axon continues to the far right, terminating at synaptic endings that connect to the central nervous system (CNS).

Draw an arrow on Figure 1 to show the direction of travel of the electrical impulse along the neurone.
