- 2. 7.1 Nervous control in7.1 Nervous control in humanshumans 1. Describe the human nervous system in terms of the central nervous system (brain and spinal cord as areas of coordination) and the peripheral nervous system which together serve to coordinate and regulate body functions. 2. Describe the structure and function of the eye, including accommodation and pupil reflex.
- 3. 7.1 Nervous control in7.1 Nervous control in humanshumans 3. Identify motor (effector), relay (connector) and sensory neurones from 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.
- 4. 7.2 Hormones7.2 Hormones 1. Define a hormone as a chemical substance, produced by a gland, carried by the blood, which alters the activity of one or more specific target organs and is then destroyed by the liver.
- 5. 7.2 Hormones7.2 Hormones 4. Compare nervous and hormonal control systems.
- 6. 7.2 Hormones7.2 Hormones 2. State the role of the hormone adrenaline in the chemical control of metabolic activity, including increasing the blood glucose concentration and pulse rate. 3. Give examples of situations in which adrenaline secretion increases.
- 7. 7.3 Tropic responses7.3 Tropic responses 1. Define and investigate geotropism (as a response in which a plant grows towards or away from gravity) and phototropism (as a response in which a plant grows towards or away from the direction from which light is coming). 2. Explain the chemical control of plant growth by auxins including geotropism and phototropism in terms of auxins regulating differential growth.
- 8. 7.4 Homeostasis7.4 Homeostasis 1. Define homeostasis as the maintenance of a constant internal environment. 4. Explain the concept of control by negative feedback. 5. Describe the control of the glucose content of the blood by the liver, and by insulin and glucagon from the pancreas.
- 9. 7.4 Homeostasis7.4 Homeostasis 2. Identify, on a diagram of the skin: hairs, sweat glands, temperature receptors, blood vessels and fatty tissue. 3. 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 vaso- constriction of arterioles supplying skin-surface capillaries and the coordinating role of the brain.
