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. The tissue that forms following healing - Which is not the same in structure as the original tissue.






2. 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.






3. A lens shape with a greater thickness at each end than through the centre.






4. A process whereby a stimulus that owes its power to conditioning loses this power by being repeatedly presented on its own; e.g. the ceasing of the capacity of a bell to trigger salivation occurs if the bell is repeatedly sounded - but without food b






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






6. The total number of people who have the condition (disease - disorder or disability) at a particular point in time - regardless of how long they have been affected.






7. Visual acuity worse than 6/60.






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






9. The total volume of gas contained in the lungs after a full inspiration (it is equal to vital capacity plus residual volume). (Abbreviated to TLC)






10. A thick ring of muscle that controls pupil size - thereby regulating the amount of light that enters the eye. It forms the coloured portion of the eye.






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






12. A two-dimensional map or projection of an object.






13. Contains protons - each of which carry a single positive electric charge - and neutrons which are uncharged.






14. The total process in an organism by which oxygen is conveyed to tissues and cells - oxidation of nutrient molecules releases useable energy - and the oxidation products (carbon dioxide and water) are given off.






15. The electrical forces holding two atoms together.






16. A graft where the donor tissue comes from another person (as opposed to an autograft where it comes from the same person).






17. A type of age-related macular degeneration (AMD) in which new blood vessels form in an attempt to restore the blood supply to the retina. The new vessels are fragile - and may leak blood into the eye.






18. A class of natural neurotransmitters that have a similar structure and action to morphine and heroin.






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






20. 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






21. 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.






22. This term indicates alcohol's effect in inducing 'psychological short-sightedness'. Alcohol lowers the range of attention - so that immediate events take on more importance than their future consequences.






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






24. 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






25. The share of the total morbidity in a population Which is due to a particular cause; it is usually expressed as a percentage.






26. For a screening procedure such as mammography - the number of true positive results expressed as a percentage of the total number of positive results (true or false). It tells (other things being equal) What the chance is that a person with a positiv






27. The cultivation of land for the purpose of crop production and/or the rearing of livestock - primarily for food - but also to provide materials - e.g. for fuel - clothing and shelter.






28. The blood pressure that is detected during heart contractions - Which is higher than the diastolic pressure.






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






30. 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






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






32. An electrically charged atom or molecule. May be positively or negatively charged; e.g. Na+ (the positively charged sodium ion) and Cl- (the negatively charged chloride ion).






33. 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.






34. A chemical reaction involving the addition of oxygen.






35. An epidemic on a world-wide scale.






36. Cells that can divide to produce daughter cells - which can then differentiate to become any of a range of different cell types.






37. A collection of neurons and other cells that is located within the protection of the backbone.






38. In screening - a person whose screening test result is negative (indicating no disease) - and who actually does not have the disease.






39. The visual condition of long-sightedness in which images of nearby objects cannot be focused sharply.






40. Counts of deaths.






41. An organelle (plural: mitochondria) in the cytosol of cells where much of cellular respiration takes place (the release of usable chemical energy from molecules derived from food).






42. A constantly repeating variation of some quantity that transfers energy from one position in a medium to another.






43. The system of muscles and bones and their various joints and linkages that facilitates support and movement in the body.






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






45. Any physical injury or severe psychological shock.






46. 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






47. A technique in which a person is placed in a particular psychological state and - in response to suggestions made by the hypnotist - can experience alterations in perception - memory and voluntary action.






48. A measure of the real impact of a particular disease - disorder or disability on people's lives (DALY) - combining an estimate of the number of years lived with a reduced quality of life - taking into account the severity of the condition (every cond






49. Matter formed from saliva mixed with mucus and any foreign material such as dust - Which is coughed up (expectorated) from the lower respiratory tract and usually ejected from the mouth.






50. Death.
