1

Systemic Anatomy

Study of Organ systems

2

Gross Anatomy

Features visible to the unaided eye

3

Cytology

Study of cells

4

Histology

Study of Tissues

5

Microscopic Anatomy

structures that cannot be seen without magnification

6

Surface Anatomy

study of general forms and superficial markings

7

anatomy

study of structure

8

physiology

study of function

9

cell

smallest living unit in organism

10

tissue

similar cells working together to perform a specific function

11

organ

group of tissues working together to perform a more generalized specific function

12

organ system

group of organs that perform a specific function

13

organism

all organ systems working together

14

Simplest level of organization

chemical level

15

integumentary system

protects against environmental hazards, controls body temp

16

skeletal system

provides support, protects tissues, stores minerals and produces blood cells

17

muscular system

provides movement and produces heat

18

nervous system

directs responses to stimuli and controls the other systems

19

Endocrine system

directs long-term changes in activities in other organ systems

20

lymphatic system

protects body against disease

21

cardiovascular system

transports nutrients and waste throughout the body

22

respiratory system

provides area fro gas exchange to occur and produces sound

23

Digestive System

processes food and absorbs nutrients

24

Urinary system

Eliminates excess water, salt, waste products

25

Reproductive system

produces sex cells and hormones and (in females) supports embryonic and fetal development

26

Homeostasis

The maintenance of a relatively constant internal environment

27

Negative feedback

Corrective mechanism that opposes or reverses a variation for normal limits and restores homeostasis

28

Positive feedback

Mechanism that increases a deviation from normal limits following an initial stimulus

29

Anterior

the front; before

30

ventral

the belly side (human anterior)

31

posterior

the back; behind

32

dorsal

the back (human posterior)

33

cranial or cephalic

the head

34

superior

above; at a higher level

35

caudal

the tail, or coccyx in humans

36

inferior

below, at a lower level

37

medial

toward the body's longitudinal axis

38

lateral

away from the body's longitudinal axis

39

Proximal

toward an attached base

40

distal

away from an attached base

41

superficial

at or near the body's surface

42

deep

farther from the body's surface

43

Abdominopelvic Quadrants

right upper, left upper
right lower, left lower

44

what makes up an atom?

proton- positive
neutron- neutral
electron- negative

45

what organic molecule is found in all living organisms?

carbon

46

covalent bond

bond that shares electron pairs between atoms

47

ionic bond

complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions.

48

cation

positively charged ion

49

anion

negatively charged ion

50

ion

atom/molecule that has an electric charge due to loss or gain of electrons

51

what is the most important fuel molecule in the body

glucose

52

where does a substrate bind to an enzyme

the Active Site

53

Median/saggital plane

left/right

54

frontal/coronal plane

front/back

55

transverse/horizontal plane

top/bottom
