Flashcards in Exam 1 Part 7 Deck (42):
1

coronal section

divides into poster/anterior sections. Think coronal suture

2

transverse section

across short axis

3

midsaggital section

left and right
-can be saggital

4

serial sectiosn

put individual images together for 3D view

5

sectioning

longitutinal, transverse, oblique (unusual angle)

6

dorsel

back

7

ventral

front

8

caudal

toward tail end

9

cranial

toward head

10

Rostral

toward the nose

11

medial

toward midpoint of body

12

lateral

away from midpoint of body

13

internal/deep

on the inside

14

external/superficial

on the outside

15

peripheral

at the edge

16

Body cavities

may be hard-walled; protect very fragile organs, which are further surrounded/protected by membranes

17

Thoriacic cavity

chest. surrounded by ribs and sternum

18

Mediastinum

Part of Thoriacic cavity between the lung
-heart, esophagus, great vessels, trachea

19

Pericardium

Part of thoriacic cavity. heart. double layer of membranes surrounding the heart

20

pleura

part of thoriacic cavity. Lungs

21

abdominal cavity

digestive organs

22

pelvic cavity

connective tissues surrounds

23

abdominopelvic cavity

both abdominal cavity and pelvic cavity

24

Body membranes

organs - have ET and Ct
Cover, separate, and support visceral organs; line obdy cavities

25

Body membrane types

cutaneous
mucous
synovial
serous

26

Cutaneous membrane

skin. ET: stratified squamous
CT: irregular dense

27

Mucous membrane

line tubes that enter/exit body
May be secretory, absorptive, protective
ET usually has goblet cells that secrete mucus
CT-lamina propria; areolar/loose fibrous CT
May include 3rd layers - muscularis mucosae

28

Synovial membrane

in some joints; most CT with incomplete ET layer
synovial fluid lubricates

29

synovial fluid

viscous, thick albumin
decreases friction of joints

30

Serous membrane

simple squamous eT
areolar/loose fibrous CT
occur as pairs
-parietal layer
visceral layer

31

Parietal layer

serous membrane that lines body cavities -does not open to outside

32

Visceral layer

serous membrane that covers organs

33

serous cavity

space between parietal and visceral layers

34

Parietal Pleura/visceral pleura

serous membranes around lungs

35

parietal pericardium/visceral pericardium

serous membranes around heart

36

parietal peritoneum/visceral peritoneum

serous membranes in the abdominopelvic cavity

37

intral peritoneal

within -covered by visceral peritoneum

38

Retro peritoneal

behind the visceral peritoneum
-kidneys, rectum, bladder

39

Mesentery

visceral peritoneum agaisnt veisceral peritoneum

40

Greater/lesser omenum

fat storage below and above stomach

41

Skeletal system

adult has 206 bones
each bone is an organ

42

Skeletal system functiosn

support, movement, protection
Hemopoiesis
fat storage
mineral storage
