1

A study of the changes in anatomy (structure) that occur in organs, tissues and cells because of injury or disease.

Pathology

2

A study of the changes in functions of organs, systems, or the body. It explains the processes that result in the development of the disease, signs and symptoms.

Pathophysiology

3

A dysfunctional change in the ability of cells / tissues / organ systems.

Disease

4

Characteristic combination of signs and symptoms associated with a particular state.

Syndrome

5

Physical, mental, and well-being

Health

6

A state of suffering or distress

Illness

7

Values occur within a range of values and may vary depending on technology used for measurement

"Normal"

8

Health indicators adjustments due to:

🔹age
🔹gender
🔹 genetic
🔹 environment
🔹 activity level

9

Sequence of events in the response of cells and tissue to a stimulus/pathogen starting from the initial stimulus to the ultimate expression of disease

Pathogenesis

10

Pathogeneses comprised of:

1. Risk factor
2. Precipitating factor
3. Ethology
4. Mechanism, progression, and resolution of disease

11

Risk factors include both:

Modifiable and non-modifiable

12

________ are triggers that promote the manifestations (sign and symptoms) of the disease.

Precipitating Factors

13

Examples of precipitating factors are:

▪️dust, animals as allergens
▪️smoking for asthmatic
▪️stress for those with CV
▪️poor nutrition for diabetes

14

____ is cause of disease

Etiology

15

_____ causes : due to inside factors

Intrinsic causes

I.e. congenital defects, genetic disorders, immune dysfunction

16

_______ causes: due to outside factors

Extrinsic causes

I.e. Trauma, burns, radiation, poisons, alcohols, bacteria, viruses, worms, insects, nutritional excess or deficit

17

Initial damage that produces effects on the body

Onset of a disease

18

typically a sudden onset that lasts a short period of time, followed by full resolution

Acute diseases

19

Typically a gradual (insidious) onset where a signs are vague or mild. (ex. Hepatitis)

🔘typically accompanied by periods of
remission and exacerbation

Chronic diseases

20

Analysis of signs and symptoms coupled with a consideration of the pathogeneses leading to the identification of the patient's disease

Diagnosis

21

Defines the probability of recovery

Prognosis

22

Probability for a reduced quality of life

Morbidity

23

Probability of death

Mortality

24

The study of disease in population

Epidemiology

25

Probability that a disease will occur (ex. 1 in 5)

Incidence

26

Number of percentage of a population with a disease (ex. 500,000 or 20%)

Prevalence

27

a stable incidence and prevalence within a given population

Endemic

28

A large rise in incidence or prevalence w/n a given population

Epidemic

29

A spread of an epidemic across continents

Pandemic
