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 pressure exerted by the Earth's atmosphere at a particular location as a result of the mass of the column of air above it. At sea level - it is 760 mmHg or 101.325 kPa.






2. The amount of air that can be forcefully expired from fully inflated lungs in the first second of expiration - abbreviated to FEV1.






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






4. The material outside the cells in a tissue in which the cells are embedded. It is mainly made from proteins made by and arranged by the cells.






5. The tissues that attach muscles to bones.






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






7. 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.






8. Microscopic organisms (bacteria - fungi and protoctists) - together with viruses - whether pathogenic (disease-causing) or harmless; also known as microorganisms.






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






10. The clinical approach to tissue repair that seeks to build new tissues in a similar manner to the way in which they form naturally (rather than the way in which they repair after damage).






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






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






13. A chemical that reduces microbial contamination of water - surfaces - etc.






14. An agent - such as a chemical - ultraviolet light - or a radioactive substance that can induce - or increase the frequency of - mutations in DNA.






15. The release of water vapour by plants.






16. 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.






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






18. One of the two main branches of the windpipe or trachea - leading to the lungs.






19. A global strategy to combat trachoma - involving eyelid surgery - antibiotic treatment - attention to facial cleanliness and environmental changes.






20. A variety of conditions associated with eyesight - from total loss of sight (blindness) to partial sight loss.






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






22. 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.






23. The pressure exerted by blood pressing on the walls of the arteries. This is frequently expressed as two numbers - systolic (higher pressure during heart contraction) and diastolic (lower pressure between heart contractions) - measured in mmHg.






24. One of a family of similar chemicals that have the generic name of 'alcohol' - with the chemical formula C2H5OH.






25. 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.






26. Tissue that is found at joints and during bone repair. Its structure is a bit like bone without the mineral component - giving a smooth and resilient surface to the ends of bones to aid movement at joints.






27. Pain that is triggered by a stimulus that causes actual or potential damage to the tissues of the body.






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






29. A volume in which there are no atoms or molecules.






30. 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






31. A measure of the amount of energy from ionising radiation absorbed per kilogram of tissue. It is measured in units of grays where 1 Gy = 1 joule per kilogram.






32. The quantity of heat required to raise the temperature of a body - or a quantity of liquid - by 1 A






33. The skin layer that lies beneath the epidermis and provides the strength and elasticity of the skin.






34. 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






35. 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.






36. Type of glaucoma in which the outflow of aqueous humour from the eye is blocked because the gap between the iris and the cornea has closed.






37. A disorder of the fetus or infant caused by excessive maternal alcohol intake during pregnancy.






38. A factor that strengthens a tendency to engage in a particular behaviour.






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






40. The smallest unit of an element that still has the properties of the element. Made up of a positively charged atomic nucleus - containing protons and neutrons - surrounded by negatively charged electrons.






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






42. Substances that have the effect of reducing pain.






43. 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.






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






45. A collection of different brain regions that is activated in response to painful stimuli and is associated with the experience of pain.






46. 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






47. Drinking to get drunk rather than just for pleasure.






48. Pain that arises from tissue damage in one part of the body - but Which is felt to be arising in a different part of the body. It is said to be 'referred to' a part that is not damaged.






49. The separation of waste products from the blood.






50. The pivot point about which a lever rotates.
