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. Structures in the kidney that filter the blood and produce the urine.






2. A narrow beam of light used to show the direction of travel of light from a source.






3. Ducts lined with epithelial cells that originate in the dermis and release sweat onto the surface of the skin.






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






5. Two or more atoms held together by chemical bonds - e.g. hydrogen (H2) - water (H2O) - carbon dioxide (CO2).






6. The concentration of ethanol in blood given in mg per 100 ml.






7. The yellow central area of the retina containing the fovea.






8. The problem of trying to explain how the subjective feelings of consciousness arise from the physical matter of the brain.






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






10. Death.






11. 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.






12. An internationally recognised health indicator - defined as the number of babies in every 1000 live births who die in their first year of life.






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






14. In screening - a person whose screening test result is positive (indicating disease) - but who actually does not have the disease.






15. An outbreak of an infectious disease in a community - region or country - characterised by a sharp increase in the number of cases - followed after an interval by a decline to a normal level






16. Tells you which type of atoms are bonded together to make up a compound or molecule - using symbols for its constituent elements. It also shows How many of each type of atom there are (e.g. the formula for carbon dioxide - CO2 - shows it has one carb






17. Diseases in which the pathogen causing the disease lives part of its life cycle in water; e.g. cholera - cryptosporidiosis.






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






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






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






21. A molecule that has both negatively and positively charged regions.






22. The pivot point about which a lever rotates.






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






24. 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'.






25. The type of blood cell that transports oxygen; also known as a red blood cell.






26. A condition in which a person exceeds a certain threshold for the proportion of body weight that consists of fat. In most assessments based on body mass index - a BMI of greater than 30 is defined as clinically obese.






27. 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






28. An atom that is better than other atoms at attracting electrons to itself; e.g. oxygen






29. 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






30. The number of new cases in a given period - usually a year - expressed as a rate per 1000 (or per 10 000 - or per 100 000 or per million) population






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






32. Injury causing physical damage to the body.






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






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






35. A characteristic of an organism is said to be adaptive if an individual possessing that characteristic has an advantage over other members of the same species in terms of survival or reproduction; e.g. ability to evade predators - attractiveness to t






36. The time between a pathogen entering its host and the host beginning to show disease symptoms; varies from one infectious disease to another.






37. A bond between two atoms formed when an outer electron from each of the atoms is shared between them to form an electron pair bond.






38. A cancer that has the ability to spread or metastasise into healthy tissue. (Also called 'invasive' cancer)






39. Often abbreviated to 'risk factors'; anything that is statistically associated with an increased chance of developing a particular disease - disorder or disability in a population; when the incidence of the disease is examined in different population






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






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






42. A fracture where the bone bends and only breaks on one side; commonest in children - whose bones tend to bend rather than break completely.






43. A form of notation (also known as 'scientific notation') used for expressing very large or very small numbers.






44. 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.






45. 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.






46. 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.






47. A medically qualified person who has chosen to specialise in clinical radiology - the use of imaging to diagnose - treat and monitor various disease processes.






48. Diseases that cannot be transmitted from person to person (also known as 'non-infectious diseases' or 'chronic conditions' or 'long-term conditions'); they mainly develop slowly over time and persist for a long period - or are irreversible; e.g. canc






49. The end of an axon which participates in a synapse with another cell.(






50. The change of thickness of the lens of the eye so that focal length changes. This allows light from objects at different distances to be sharply focused in turn on the retina.
