1. Describe the human nervous system in terms of the central nervous system and the peripheral nervous system.
2. Describe the structure and function of the eye, including accommodation and pupil reflex.
3. Identify motor (effector), relay (connector)and sensory neurones and draw diagrams.
4. Describe a simple reflex arc in terms of sensory, relay and motor neurones, and a reflex action as a means of automatically and rapidly integrating and coordinating stimuli with responses.
5. Define a hormone as a chemical substance, produced by a gland and carried by the blood.
6. State the role of the hormone adrenaline in the chemical control of metabolic activity, including increasing the blood glucose concentration and pulse rate.
7. Compare nervous and hormonal control systems.
8. Give examples of situations in which adrenaline secretion increases.
9. Define and investigate geotropism and phototropism.
10. Explain the chemical control of plant growth by auxins including geotropism and phototropism in terms of auxins regulating differential growth.
11. Define and Identify, on a diagram of the skin: hairs, sweat glands, temperature receptors, blood.
12. Describe the maintenance of a constant body temperature in humans in terms of insulation and the role of temperature receptors in the skin, sweating, shivering, vasodilation and vasoconstriction of arterioles supplying skin-surface capillaries and the coordinating role of the brain. vessels and fatty homeostasis.
12. Explain the concept of control by negative feedback.
13. Describe the control of the glucose content of the blood by the liver, and by insulin and glucagon from the pancreas.
