The diagram shows a motor neurone.

A diagram of a motor neurone. It shows a central cell body with many branch-like dendrites. Extending from the cell body is a long, thin nerve fibre. Along the length of this nerve fibre are several sausage-shaped insulating segments wrapper around it. Label F points to one of these outer insulating segments. Label G points to the long, inner nerve fibre itself.

Name both structure F and structure G.
