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 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






2. A chemical reaction involving the addition of oxygen.






3. 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






4. 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.






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






6. A muscular wall separating the chest (thoracic) cavity from the abdominal cavity in mammals.






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






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






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






10. A break in one of the helical strands of a DNA molecule - caused by ionising radiation.






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






12. The movement of atoms or molecules from a region of higher concentration to a region of lower concentration - until the concentration is the same throughout the available volume. Atoms and small molecules can also move across a permeable cell membran






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






14. 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






15. High blood pressure in the blood vessels supplying the lungs - a sign that blood flow is restricted in some way.






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






17. 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.






18. Immobilisation of a broken bone using something rigid.






19. Tiny particles of calcium that appear as small specks on a mammogram. When clustered in one area of the breast - they may indicate the presence of cancer cells.






20. 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






21. 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.






22. An intense conscious occupation with thoughts of the object of an addiction.






23. The total number of people who have a disease - disorder or disability at a particular point in time - expressed as a rate per 1000 (or per 10 000 - or per 100 000 or per million) population.






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






25. The flat cells that line the cardiovascular system.






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






27. 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






28. A device that produces light of a single wavelength Which is transmitted in a narrow and powerful beam.






29. 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.






30. 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.






31. The part of a neuron that consists of a long wire-like projection - ending in a terminal which participates in a synapse with another cell. Action potentials are transmitted along these.






32. A small unit of energy frequently used by physicists and denoted by the symbol eV.






33. 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






34. An epidemic on a world-wide scale.






35. Rigid structures (such as bones) that can move about a fulcrum in response to forces in order to transfer force from one place to another. They can modify the size of the force and the distance of motion.






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






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






38. 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).






39. A scale from 0 to 14 describing the acidity or alkalinity of a solution - where 7 is neutral - greater than 7 is more basic (alkaline) and less than 7 is more acidic.






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






41. 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.






42. An eye care professional qualified to perform eye tests and record the findings in a lens prescription.






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






44. The pressure that one component of a mixture of gases would exert if it were alone in a container.






45. A break in both of the helical strands of a DNA molecule - caused by ionising radiation.






46. A physiological reaction occurring in the body - triggered by the perception of aversive or threatening situations.






47. To breathe more rapidly and deeply than normal.






48. 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.






49. The electrical forces holding two atoms together.






50. 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
