Introduction To Health Sciences Vocab

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. Recognisable assemblages of plants and animals - such as woodland - grassland - rivers - etc. - in which a distinct set of plants and animals live together and interact with one another.






2. The entire range or extent of some quantity - arranged in order; e.g. electromagnetic or visible light.






3. Disease - disorder or disability.






4. Most common type of age-related macular degeneration - in which the blood supply to the retina is reduced - resulting in gradual loss of vision.






5. A measure of how well a person sees - determined by the minimum distance at which two lines (or points) can be distinguished at a test distance.






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






7. The proportion of young - middle-aged and older people in a population. In developing countries - tends to be 'younger' than that of developed countries.






8. The total amount of air that can be forcefully expired from fully inflated lungs - abbreviated to FVC.






9. 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.






10. The share of all deaths in a population Which is due to a particular cause; it is usually expressed as a percentage.






11. An experience Which is accessible only to the person who experiences it in terms of the contents of his or her conscious mind. Such experience is not open to objective observation or measurement by any other individual and hence is contrasted with 'o






12. That part of the nervous system that exerts control over the skeletal muscles and thereby over behaviour.






13. Countries that provide universal education for their children - with populations that have high rates of literacy - comprehensive health services and which meet certain other development indicators - such as 100% access to safe drinking water and san






14. Negatively charged particle of almost no mass that surround the nucleus of an atom.






15. Vital to many chemical reactions in the body. Crystals containing these form an important part of the structure of bones.






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






17. A shell - typically made from plaster or fibreglass - which can be put around a limb in order to encase and support a broken bone until it has healed.






18. The process of reducing pain - e.g. by taking morphine.






19. A technique for monitoring the activity of the different regions of the brain. One method involves injecting a radioactive tracer substance and measuring its later appearance in different brain regions; high concentrations correspond to regions of hi






20. A) A transparent and flexible convex structure behind the iris that (together with the cornea) refracts light. b) A transparent object - usually made of glass or plastic - that refracts light. Found in spectacles - magnifying glasses and microscopes.






21. Immune system cells that circulate around the body helping to protect it from infection and some other types of disease; also known as white cells.






22. A study in which neither the participants (e.g. patients) nor the experimenters (e.g. therapists) know into which group the participants have been allocated (e.g. either drug or placebo groups).






23. Fuel derived from plant matter or animal waste - e.g. wood - straw - dried animal dung.






24. A subunit of the litre - the standard scientific (SI) unit for measuring volume; there are 100 of these in a litre.






25. A) A process in which the photon energy is captured by a medium - without transmission or reflection. b) The process by which the molecules released from digested food pass through the wall of the gut and into the surrounding blood vessels.






26. A visual impairment in which the lens of the eye loses transparency and exhibits reduced light transmission.






27. A covalent bond formed by the sharing of two electrons - one from each atom at either end of the bond.






28. A physiological reaction occurring in the body - triggered by the perception of aversive or threatening situations.






29. A disease in which an excessive loss of bone structure occurs.






30. An early and reversible consequence of excessive alcohol consumption during which fat accumulates within the cells of the liver.






31. The layer of the eye - between retina and sclera - which absorbs any light that has not interacted with the rods and cones in the retina.






32. A single point on the optical axis of a lens onto which all light rays parallel to that axis are directed.






33. Condition in which the full range of colours cannot be clearly distinguished.






34. A study in which the participants do not know into which group they have been allocated - e.g. whether they have received a drug or a placebo.






35. Refers to an infectious disease that can be transmitted by physical contact.






36. The energy needed to break a bond between two atoms.






37. The body system consisting of the heart - blood vessels and blood. It circulates blood throughout the body and is also known as the circulatory system.






38. Brain region involved in processing memories and emotional reactions.






39. The opening at the centre of the iris that allows light to enter into the eye.






40. A cancer that has the ability to spread or metastasise into healthy tissue. (also known as 'malignant' cancer)

45. The process of expiring or breathing out; the emission of air from the lungs.






46. The part of a neuron that consists of a long wire-like projection - ending in a terminal which participates in a synapse with another cell. Action potentials are transmitted along these.






47. Rigid structures (such as bones) that can move about a fulcrum in response to forces in order to transfer force from one place to another. They can modify the size of the force and the distance of motion.
