Subject : health-sciences
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A visual impairment in which the lens of the eye loses transparency and exhibits reduced light transmission.






2. To breathe more rapidly and deeply than normal.






3. Molecules or proteins released by immune system cells in the region of an injury - infection or other damage to the tissues. They have several effects including dilation (widening) of blood vessels to increase blood supply to the region. They also at






4. The number of cases of a disease - disorder or disability in a population - relative to the total number of people at risk of developing it; usually expressed as the number of cases per 1000 (or per 10 000 - or per 100 000 or per million) population.






5. A tissue made up of cells embedded in a matrix of protein fibres which includes bones - fat and tendons; they connect - support - or surround other tissues and organs.






6. A qualified doctor who has specialised in the diagnosis and treatment of eye conditions - and who can perform eye surgery.






7. The structure within the eye where the iris meets the cornea - where excess aqueous humour from the front of the eye can drain.






8. A type of chemical bond formed between a partial positive charge on a hydrogen atom and a partial negative charge on another atom. In more detail - the bond is formed by the electrical attraction occurring between the partial positive charge remainin






9. Pain that arises from damage to neurons either within the central nervous system or in the periphery of the body.






10. Deliberately deciding never to drink alcohol.






11. The neuron that stores and releases neurotransmitter at a synapse with another neuron or a muscle cell.






12. The distance between the principle focal point and the centre of a lens.






13. The production of any colour by varying the relative intensities of the subtractive primaries (cyan - magenta and yellow).






14. Memory for events or issues related to oneself.






15. A cell that is part of a malignant tumour; not subject to the body signals that tell normal cells when to divide or stop dividing - so they multiply in an uncontrolled way.






16. A class of neuron that detects the presence of stimuli in the world - such as tactile events - heat - cold or tissue damage.






17. Abnormally high acidity (excess hydrogen ion concentration) of the blood and other body tissues.






18. Blood vessels that convey blood away from the heart.






19. An estimate of the probability of developing a particular disease or disorder in a population that has been exposed to a particular risk factor - relative to the probability of developing the condition if the risk factor was not present.






20. Much of the brain is divided down its midline into two halves - the left and right of this; also referred to as the 'left brain' and the 'right brain'.






21. The unit of absorbed dose of ionising radiation; 1 Gy = 1 joule per kilogram of tissue.






22. Severe psychological shock.






23. A screening programme (sometimes called 'mass screening') that aims to screen everyone in a particular population group (rarely every citizen) - e.g. everyone over the age of 50 years - or all newborn babies. Attempts are made to screen everyone in t






24. An insoluble fibrous protein that forms clots following tissue damage.






25. Literally meaning 'alien to nature' - the term is commonly used to refer to chemicals in the natural environment that are of human origin.






26. The number of photons passing through a given area per second.






27. Over time - a need for an increasing amount of drug to obtain the same level of effect - e.g. the amount of alcohol required to produce intoxication.






28. The light-sensitive tissue at the back of the eyeball that contains the visual receptor cells (rods and cones).






29. Cells that cover all surfaces of the body. (CS 3 - 4 - 6 & 7)






30. The statistical study of the occurrence - distribution - potential causes and control of diseases and disabilities in human populations (CS 1 - 3 - 4 & 6)






31. The joining of tissues to each other that may occur abnormally during repair.






32. A group of steroid hormones produced mainly by the ovaries (some are also produced by fat deposits in the body) - which are responsible for promoting the development and maintenance of female sexual characteristics.






33. A sensory nerve cell or group of cells that responds to a chemical stimulus.






34. A clearly stated provisional explanation for a set of observations or data - devised for the purpose of testing its validity by the collection of additional data or by conducting an experiment.
