State one difference between nervous and hormonal control systems.
State one difference between nervous and hormonal control systems.
Fig. 3.1 is a diagram of the junction between two neurones in a healthy person.
Fig. 3.2 is a diagram of the junction between the same two neurones in a person who has Parkinson's disease. This disease affects the nervous system.

A neurone is a type of specialised animal cell.
Nerves and hormones coordinate the functions of the body.
Suggest why blinking of the eyes is coordinated by nerves and not hormones.
