1

Characteristics of living things:

1) Cells
2) organized and complex
3) Reproduction
4) Respond to stimulus
5) Require energy
6) Exchange materials with environment
7) Development and growth
8) DNA - genetic material of living things
9) Regulation

2

Biology

Study of life

3

Physiology

Function

4

Anatomy

Structure

5

Four kinds of tissue:

Epithelial, muscle, connective, nervous

6

Epithelial tissue

Lines things

7

Muscle tissue

Work together to move things

8

Connective tissue

Connect one type of tissue to another

9

Nervous tissue

Electrical signals

10

Coronal

Cut perpendicular with ground from ear to ear
Cut face off

11

Transverse

Cut parallel with ground

12

Midsaggital

Cut perpendicular with ground

13

Superior

(Cranial)
Above

14

Inferior

(Caudal)
Below

15

Ventral

(Anterior)
Front of body
(Stomach side (in front) of four legged animals or Dolphins)

16

Dorsal

(Posterior)
Back of body
(Back side of (behind) four legged animals or Dolphins)

17

Medial

Toward center of body
Midline

18

Lateral

Away from midline

19

Intermediate

Between medial and lateral structures

20

Proximal

Closer to point of attachment of limb or trunk

21

Distal

Farther to point of attachment of limb or trunk

22

Superficial

(External)
Toward surface of body

23

Deep

(Internal)
Away from surface

24

Axial region

Head, neck and trunk

25

Appendicular region

Arms and legs

26

Serous membrane

Allows frictionless movement
Surround the organs in the ventral cavities

26

Dual-layered

Folded in on itself
(Parietal and visceral)

27

Parietal serous membrane

Fused to cavity wall

28

Visceral serous membrane

Membrane nearest the organs (aka viscera)

29

Thoracic cavity compartments:

Pleural cavities (2)
Mediastinum
Pericardial

30

Homeostasis

1) Body's ability to maintain relatively stable conditions even though outside environment changes continuously.
2) Dynamic state of equilibrium.
3) Body is in homeostasis when it's needs are met and it is functioning smoothly.

31

Negative feedback

- common mechanism of regulation
- causes variable to change in opposite direction of initial change
Ex. Thermostat

32

Positive feedback

- less common mechanism of regulation
- causes variable to be enhanced in direction of initial change
Ex. Contractions, breastfeeding

33

Gross anatomy

Examining large structures

34

Organ Systems

Groups of organs that function together in a coordinated manner
