1

The basis for communication in anatomy and physiology assumes _____?

Anatomical position

2

Dorsal Cavities (2)

Cranial and Vertebral

3

Ventral Cavities (2)

Thoracic and abdominopelvic

4

Superior and anterior

S: toward the head- I: toward the feet

5

Proximal and distal

P: closer the sagittal D: farther from sagittal } extremities

6

Anterior (ventral) and posterior (dorsal)

Ventral: front of body/organ
Dorsal: back of body/organ

7

Sagittal plane

Divides body in half at the midpoint

8

Frontal plane

divides body in anterior and posterior

9

Transverse

divides superior and inferior

10

Medial and lateral

medial is towards sagittal
Lateral away from sagittal

11

Separates thoracic and abdominal pelvic cavity

Diaphragm

12

Pericardium: heart

Visceral: covers the heart
Parietal: covered by fibrous pericardium

13

Pleura: lungs

Visceral: covers lungs
Parietal: lines cavity walls

14

Peritoneum: abdominal

Visceral: covers abdominal organs
Parietal: lines cavity walls

15

Protection: skin, nails, hair

Integumentary

16

Support and protection: bones, ligaments

Skeletal

17

Movement: skeletal muscles, tendons

Muscular

18

Detects change & sensory: brain, spinal cord, nerves

Nervous

19

Hormones: glands, pancreas, ovaries, testes

Endocrine

20

Transports: heart, arteries, veins

Cardiovascular

21

Immune cell production: lymph nodes, spleen

Lymphatic

22

Gas exchange: pharynx, larynx, lungs

Respiratory

23

Breakdown and absorption: mouth, stomach, intestines

Digestive

24

Removes waste and liquid: kidneys, uterus, bladder

Urinary

25

sperm and egg production, fetal development: penis, vagina, ovaries, testes

Reproductive systems

26

Protective layer that bounds cells

plasma membrane

27

power house, center of control

nucleus

28

surrounds and protects nucleus

nucleus membrane

29

center of nucleus: contains ribosomal RNA and protein

Nucleolus

30

Strands of DNA: represents your genetic coding

chromatin and DNA

31

membrane network attached to ribosomes: protein synthesis cellular transportation

Rough endoplasmic reticulum

32

membrane network without ribosomes: lipid synthesis and cellular transport

Smooth endoplasmic reticulum

33

flattened sacs near nucleus: packing glycoproteins for transport and secretion

Golgi Apparatus

34

double membrane with folded inner membrane: synthesis of ATP

mitochondria

35

Sacs containing digestive enzyme: destroys cellular debris and worn-out organelles

lysosomes

36

proteins in cilia, flagellum & centrioles: support and mobility within cells

microtubules cytoskeleton

37

threads of protein actin: maintain & change cell shape, muscle contraction within cell mobility

micro fibrils cytoskeleton

38

movement along concentration gradient from high to low

diffusion

39

diffusion of water molecules across the plasma membrane

osmosis

40

solution with high solute concentration

hypertonic

41

solution with low solute concentration

hypotonic

42

relatively equal number of solute molecules and solvent molecules

isotonic

43

cells grow, synthesize material needed for S phase

G1 phase

44

replicates DNA

S phase

45

completes growth and production of enzymes

G2 phase

46

chromosomes condense and become visible
spindle apparatus form
centrioles migrate

prophase

47

chromosomes align along metaphase cell
spindle attach to kinetochores
extend from centrosome

metaphase

48

spindle fivers pull sister chromatid to opposite poles
each pole has identical set of genes

anaphase

49

nuclear envelope reassembles
chromosomes re-condense
spindle disappears
divides into 2 cells

telophase
