define prodromal period
the time during which patient experiences vague
symptomes such as fatique or loss of appetite before the
onset of specific signs and symptoms.
3 terms for death in latin
mors, mortis
exitus letalis
define normality
What is termed a normal value for a laboratory test is established statistically from test results obtained from a selected sample of people/animals.
The normal values refer to the 95% distribution (mean plus or minus two standard deviations [mean ± 2 SD]) of test results for the reference population.
Reliability refers to
the extent to which an observation, if repeated, gives the same result.
Validity refers to
the extent to which a measurement tool measures what it is intended to measure.
This often is assessed by comparing a measurement method with the best possible method of measure that is available.
Although predictive values rely in part on sensitivity and specificity, they depend more heavily on
the prevalence of the condition in the population.
Despite unchanging sensitivity and specificity, the positive predictive value of an observation rises with prevalence, whereas the negative predictive value falls.
define self-limiting
(a.k.a. self-recovering) is a term used in clinical medicine to refer to any disease whose natural history is to resolve without treatment
define recidiviation
to relapse into a previous condition or mode of behavior: to exhibit recidivism
These symptoms are then called recidive.
alt. term for relapse
recidiviation, recidive
define metaphylaxis

Metaphylaxis is always combined with the treatment of the diseased individuals.

define insolation
exposure to the sun’s rays.
the amount of solar radiation reaching a given area.
name 3 types of radiation capable of causing injury
- Ionizing Radiation
- Ultraviolet Radiation
- Nonionizing Radiation
describe Ionizing Radiation injury
Causes ionization of molecules and atoms in the cell, by directly hitting the target molecules in the cell, or by producing free radicals that interact with critical cell components.
describe Ultraviolet Radiation
The degree of risk depends on:
the type of UV rays,
the intensity of exposure, and
the amount of protective melanin pigment in the skin.
describe Nonionizing Radiation injury
Unlike ionizing radiation, which can directly break chemical bonds,
nonionizing radiation exerts its effects by causing vibration and rotation of atoms and molecules.
Phytophotodermatitis caused by
contact with the photosensitizing compounds found naturally in some
plants and vegetables like parsnips, citrus fruits, and more.
is a form of plant dermatitis
alt. terms for Sunburn and Photodermatitis
sun poisoning
photoallergy
Teratogens are
environmental agents that can harm the developing fetus
Teratology is the study of
