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. Drinking to get drunk rather than just for pleasure.






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






3. The thinnest blood vessels.






4. 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.






5. A measure of the dose of ionising radiation to an organism which takes into account the sensitivity to radiation of different organs in the body. Multiplied by a tissue weighting factor for that organ. Then the amounts for all the affected organs are






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






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






8. Counts of deaths.






9. The term given to those units of measurement that scientists all over the world have agreed to use in their publications; e.g. the second (s) - the kilogram (kg) - and the metre (m).






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






11. 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.






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






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






14. A class of animals characterised by having the body covered in hair - by having a four-chambered heart - and by feeding their young on milk produced by the female.






15. A small airway branching from a bronchus.






16. Qualified to employ a range of equipment such as X-rays - MRI scanners - etc. to produce images to diagnose an injury or disease. They will then have undergone further specialist training in mammography. (Two types - diagnostic and therapeutic; the l






17. The effects of ionising radiation are said to be this if there is a threshold below which there is no effect - and if above that threshold - the severity depends on the amount of radiation received.






18. Disease - disorder or disability.






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






20. A general loss of intellectual abilities including memory - judgement and abstract thinking - as well as personality changes.






21. A bean-shaped tissue packed with immune system cells found at intervals along the vessels of the lymphatic system. They filter potentially harmful substances and organisms (microbes) from body fluids that drain into the lymphatic system; the filtered






22. A chemical that has the effect of blocking the action of a natural substance such as a neurochemical. (






23. 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.






24. A bundle of the axons of neurons in the peripheral nervous system. (Occasionally employed informally to refer to a bundle of axons within the central nervous system.)






25. The neuron that has receptors for the neurotransmitter released by a presynaptic neuron at the junction (synapse) between these adjacent cells.






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






27. Any physical injury or severe psychological shock.






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






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






30. A system of glands (also known as ductless glands) - each of which secretes one or more hormones directly into the bloodstream. (CS 1 - 2 & 3)






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






32. An uncharged particle in the nucleus of an atom.(






33. 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.






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






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






36. The system of organs and structures in which gas exchange takes place. In mammals it consists of the airways - the lungs and the muscles that mediate the movement of air into and out of the lungs.






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






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






39. 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






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






41. The build-up of levels of a chemical contaminant in the bodies of animals at successive levels in a food chain.






42. A process causing evolutionary change over time (from one generation to the next). Individuals that hold an advantage in terms of survival and reproduction - in competition with other individuals - will pass on characteristics that contribute to that






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






44. Haemoglobin bound to oxygen molecules. Transports oxygen from blood vessels in the lungs to the cells in the rest of the body.






45. The process whereby oxygen is taken up by cells and used in chemical reactions involving the oxidation of nutrient molecules (e.g. glucose) derived from food; these reactions release usable chemical energy for cellular processes. (CS 5 & 7)






46. Deliberately deciding never to drink alcohol.






47. The unit used to measure equivalent dose and effective dose (Sv).






48. Particulates suspended in air that are less than 10 micrometres in diameter.






49. A molecule that facilitates a reaction but Which is left unchanged at the end; catalysis refers to the action of this.






50. A tube conveying a body fluid - especially a glandular secretion - for example milk from the lobules of the mammary gland to the nipple.
