containing vesicles, the synaptic cleft and neurotransmitter receptor molecules Define how an impulse causes the release of a neurotransmitter from vesicles into the synaptic gap and how the neurotransmitter diffuses across to bind with receptor molecules, in the membrane of the neurone after the synaptic gap, causing the impulse to remain List that in a reflex arc the synapses ensure that impulses travel in one direction only Outline that many drugs, 14.2 Sense organsCore Outline sense organs as groups of receptor cells responding to specific stimuli: light, sound, touch, temperature and chemicals Recognise the structures of the eye, restricted to cornea, iris, pupil, lens, retina, optic nerve and blind spot Define the purpose of each part of the eye, limited to: cornea, refracts light, iris, controls how much light enters pupil, lens, focuses light onto retina, retina, contains light receptors, some sensitive to light of different colours, optic nerve, carries impulses to the brain Clarify the pupil reflex in terms of light intensity and pupil diameter only, Supplement Describe the pupil reflex in terms of light intensity and antagonistic action of circular and radial muscles in the iris Describe accommodation to view near and distant objects in terms of the contraction and relaxation of the ciliary muscles, tension in the suspensory ligaments, shape of the lens and refraction of light State the distribution of rods and cones in the retina of a human List the meaning of rods and cones, limited to greater sensitivity of rods for night vision and three different kinds of cones absorbing light of different colours for colour vision Recognise the point of the fovea, 14.3 Hormones in humansCore Express a hormone as a chemical substance, created by a gland and carried by the blood, which alters the activity of one or more specific target organs Recognise specific endocrine glands and their secretions, limited to adrenal glands and adrenaline, pancreas and insulin, testes and testosterone and ovaries and oestrogen Pronounce adrenaline as the hormone secreted in fight or flight situations and its effects, limited to improved breathing and pulse rate and widened pupils (knowledge to do this 0610 IGCSE Biology past year papers) Provide examples of situations in which adrenaline secretion increases List the utilities of insulin, oestrogen and testosterone, Supplement Evaluate the role of the hormone adrenaline in the chemical control of metabolic activity, with increasing the blood glucose concentration and pulse rate Compare hormonal control systems and nervous in terms of speed and longevity of action, 14.4 Homeostasis Core Explain homeostasis as the maintenance of a continuous internal environment Name and identify on a diagram of the skin: sweat glands, receptors, sensory neurones, blood, hairs, hair erector muscles, vessels and fatty tissue Define the upkeep of a constant internal body temperature in humans in terms of sweating, shivering, insulation, and the role of the brain (limited to blood temperature receptors and coordination), Supplement Describe that homeostasis is the control of internal conditions within set limits Describe the concept of control by negative feedback Explain the control of the glucose concentration of the blood by the liver and the roles of insulin and glucagon from the pancreas State the symptoms and treatment of Type 1 diabetes (detail of cells is not required) Describing the maintenance of a constant internal body temperature in humans will be examined in these IGCSE Biology past year papers in terms of vasodilation and vasoconstriction of arterioles supplying skin surface capillaries, 14.5 Tropic responsesCore Explain gravitropism as a reply in which parts of a plant grow towards or away from gravity Explain phototropism as a answer in which parts of a plant grow towards or away from the way from which light is coming Explore gravitropism and phototropism in shoots and roots, Supplement Explaining the phototropism and gravitropism of a shoot as examples of the chemical control of plant growth will be tested in these IGCSE Biology past year papers Describe the role of auxin in controlling shoot growth, limited to: auxin made in shoot tip (only), auxin spreads through the plant from the shoot tip, auxin is unequally distributed in response to light and gravity, auxin stimulates cell elongation Explain the use in weed killers of the synthetic plant hormone 2,4-D, 15.2 Medicinal drugs Core Explain the purpose of antibiotics for the handling of bacterial infection Outline that some bacteria are unaffected to antibiotics which reduces the effectiveness of antibiotics State that antibiotics destroy bacteria but do not upset viruses, Supplement Explain how improvement of resilient bacteria such as MRSA can be reduced, limited to using antibiotics only when essential and ensuring treatment is completed Explaining why antibiotics kill bacteria, but do not affect viruses will be examined for these IGCSE Biology past year papers, 15.3 Misused drugs Core Explain the effects of excessive alcohol intake and misuse of heroin, limited to: powerful depressant drugs, effect on reaction times and self-control, addiction and withdrawal symptoms, negative social implications, e.g. And effects of protein-energy malnutrition, e.g covers both the Core and the.
