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.

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.
centilitre
greenstick fracture
glaucoma

23. The process of expiring or breathing out; the emission of air from the lungs.
expiration
psychological trauma
body mass index
gate theory
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.
heat capacity
closed-angle glaucoma
electromagnetic radiation
proportional morbidity
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
