Flashcards in Quiz 1 a&p terms Deck (23):
1

Gross anatomy

-Study by inspection
-Organs and major structures

2

Histology

Study of tissues and cells that make up organs

3

Cytology

Study of cell structure of particular cell types

4

Molecular biology

Study of the molecules that make up the organism

5

Scientific method

-Truths discovered by testing

-“If it isn’t testable, it isn’t science”

6

Hypothesis

A testable guess as to an underlying truth

7

Experiment

The testing of the hypothesis

8

Data

Info derived from experiments

9

Theory

Hypothesis that is supported by data

10

Scientific fact

A theory that has been tested exhaustively ;
(Very rare)

11

Theory of evolution

Things change

12

6 characteristics that define LIFE

-it is organized: there is definite structure
-it is made of cells: the units of life
-it metabolizes: set of carefully controlled complex chem rxns(eat, drink, sleep, defecate, exercise)
-responds to stimuli: this is quite variable
-it is homeostatic: attempts to maintain a constant internal environment
-it reproduces: there is a mechanism for continuity

13

Anatomy

-Ana: one’s self
-tomy: to cut

14

Physiology

-The study of function
-Arranged by type of function

15

Morphology

Study of shape related to fun.

“The heart is shaped like a pump.”

16

Embryology

-the study of development
-how organisms arise from primordial cells

17

Biochemistry

-Study of all chem. Interactions in an organism

18

Pathology

Study of how homeostasis is NOT maintained in an organism.

19

Pathology:
1) etiology
2) diagnosis
3) prognosis

1) why do you have that disease? Where does it come from?
2) what is it?
-syndrome-don’t know what it is
-autoimmune—not an infection/disease but acts like one. Body attacks self.
3) how to treat it/how to survive it.

20

Homeostasis

-maintenance of a constant internal enviro.
-balance
-from conception—> 16/18 years old, it is NOT maintained because everything is changing/growing/developing.
-at 21–>29 it is maintained, then it starts getting harder. As you age, the harder it gets.

21

Feedback loops

???

22

Negative feedback

-inhibits the deviation from the norm
-many homeostatic mechanisms are designed to stay at a “set point”. When it deviates, the negative feedback returns the level to “set point”.

23

Positive feedback

-encourages the change/catalyst
Ex. Blood clots; once the original clotting mechanism begins, it sends a positive feedback encouraging more clotting. Let’s keep going!
