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. A simple way of presenting numerical data visually - so as to emphasise the relative size of different numbers. May be arranged vertically or horizontally.






2. A brain region with an essential role in the storage and retrieval of memories.






3. Microbes that cause disease.






4. Substances in which an interaction or reaction occurs - or in which an event takes place - or chemicals or objects are transported or supported - e.g. a medium through which a wave is transmitted in the refraction of light.






5. An alternative way of modelling the energy from an electromagnetic wave; small packets of energy and the energy of each depends on the frequency of the electromagnetic wave.






6. The process of urban development - i.e. of towns and cities - and the movement of an increasing proportion of a country's population from rural to urban environments.






7. A long chain molecule made up of many repeating units.






8. Visual acuity worse than 6/60.






9. An eye-surgery technique where the epithelial layer of the eye is removed and laser treatment applied to the tissues exposed beneath (abbreviated to PRK).






10. Pain of relatively short duration and associated with actual damage to tissues.






11. A mathematical adjustment that enables disease and mortality rates to be compared from countries with different age-structures - i.e. different proportions of young - middle-aged and older people in their populations. The method involves taking a ver






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






13. A condition in which the optic nerve becomes damaged - usually because the pressure of fluid within the eye becomes too high - leading to a progressive loss of vision.






14. The volume of air inhaled and exhaled at each breath when resting (abbreviated to TV).






15. Screening that takes place haphazardly when an opportunity arises - for example - when a patient consults a doctor about something unrelated and is referred for a screening test.






16. The organelles found inside myofibres that run the length of the cell and cause contraction.






17. A value which can be used to calculate the degree to which X-rays (or other radiation) are reduced in intensity when passing through a material (e.g. human tissue).






18. The type of bone that is less dense (compared with compact bone) and contains struts (trabeculae) to provide strength. It is found within the widened areas inside the ends of the bones.






19. 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.






20. The time between one peak of a wave and the next .






21. The flow of blood back to the heart in the veins.






22. Colours of light (red - blue and green) which - when added together - make white light.






23. The integrated body system of organs - tissues - cells and proteins that functions to protect the body from potentially pathogenic organisms (microbes) or harmful substances.






24. A protein that is abundant in the extracellular matrix and can form long thin fibres to provide structure to many tissues.






25. A graph recording breathing - Which is made with a spirometer.






26. A thin membrane (a double layer of lipids) enclosing the cytosol and organelles of a cell.






27. 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).






28. The electrical forces holding two atoms together.






29. The electrical forces holding two atoms together.






30. The curved transparent layer that covers the front part of the eye. This (together with the lens) refracts light to form of an image on the retina - as well as protecting the eye from frontal damage.






31. 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.






32. The study of toxins and their effects on living organisms.






33. A substance produced by an endocrine gland that is carried around the body in the blood - and affects the structure or functions of specifically receptive target organs or tissues.






34. The areas of the medulla region in the brain that integrate sensory information from chemoreceptors monitoring the level of oxygen and carbon dioxide in the blood. They send out appropriate signals to regulate the rate of contraction of the respirato






35. The transparent fluid that fills the space between the cornea and the lens of the eye.






36. Degenerative disease of the retina that results in loss of vision in the centre of the visual field. It is caused by an impaired blood supply to the macula. This condition is usually associated with ageing.






37. A very long macromolecule found in the cell nucleus - abbreviated to DNA. It is the main component of chromosomes and is the material that transfers genetic characteristics through the generations in all organisms. The genetic information is carried






38. A technique where people learn to change their thought patterns and behaviour to create feelings of coping and self-efficacy; e.g. people in chronic pain might be taught to place a less catastrophic interpretation on their pain.






39. Countries that are only partly industrialised and where national wealth is below that of the developed economies (also known as low- and middle-income countries). They rely to a much greater degree than developed countries on subsistence farming - sm






40. The ability to stand - walk and run - supported only by the hind limbs.






41. The study of the relationship between the structure and the function of body systems.






42. 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






43. A tissue that covers a surface or lines a space inside the body - forming a barrier or interface across which substances are absorbed or secreted - e.g. the skin - gut lining - and various glands.






44. A region of cortex at the front of the brain - where the activity of neurons is associated with voluntary control of behaviour (self-control) and restraint. Biological evidence suggests that mild to moderate doses of alcohol selectively depress the a






45. A substance (usually liquid) in which other substances dissolve.






46. The environmental factors impacting on survival and reproduction in a population of organisms in which there is variation between individuals in their ability to withstand adverse conditions or benefit from advantageous circumstances. The result of t






47. A process in which light passes through a medium unaffected - e.g. light passing through clear glass.






48. A chemical that is stored within the axon terminal of a neuron and is released in response to electrical activity within that neuron. It passes the short distance to a neighbouring cell (neuron or muscle cell) where it binds to a neurotransmitter rec






49. A process at an interface of two media in which the direction of light is deviated within the new medium.






50. A condition in which the conjunctiva is inflamed.
