Flashcards in Animal form Deck (40)
1

epithelial tissue

covers the outside of the body and lines organs and cavities within the body; riveted by tight junctions

2

glandular epithelia

absorb or secrete chemical solutions; such as mucous membranes

3

epithelial layers

simple-single; stratified-multiple; pseudostratified-single, length varies

4

epithelial shape

cuboidal; columnar; squamous-floor tiles

5

connective tissue

fibers that function mainly to bind and support other tissues

6

collagenous fibers

nonelastic collagen protein for strength in pinching and pulling

7

elastic fibers

elastin protein for the rubbery pulling of skin back into shape

8

reticular fibers

forms a tightly woven fabric that joins connective tissue to adjacent tissues

9

muscle tissue

skeletal, cardiac, and smooth

10

basement membrane

at the base of an epithelial layer; dense mat of extracellular matrix

11

fibrous connective

large number of collagenous fibers; maximizes nonelastic strength

12

tendons

attach muscle to bone; fibrous connective

13

ligament

joins bones together at joints; fibrous connective

14

cartilage

chondrocytes secrete rubbery matrix; absorbs pressure without breaking

15

loose connective

binds epithelia to tissue and holds organs in place; fibroblasts and macrophages present

16

adipose tissue

form of loose connective; stores fat in droplets

17

blood

has extensive extracellular matrix in plasma

18

skeleton

bone- mineralized connective tissue made from osteoblasts

19

osteon

mammalian bone consists of these repeating units

20

skeletal muscle

striated muscle; fiber with bundles called myofibrils

21

sarcomere

contractile units along the length of myofibril bundles gives striated appearance

22

cardiac muscle

striated as well but is not voluntary; has intercalated disks for signal relay

23

smooth muscle

spindle shaped; involuntary body activities

24

nervous tissue

nerve cells are the basic units of the nervous system

25

mucosa

inner epithelial layer that lines the stomach lumen

26

submucosa

matrix of connective tissue that contains blood vessels and nerves

27

muscularis

consists mainly of smooth muscle tissue

28

serosa

thin layer of connective and epithelial tissue

29

thoracic cavity

body cavity that houses the lungs and heart

30

endothermic

bodies are warmed mostly by heat generated by metabolism; body temp maintained within narrow range

31

ectothermic

gain most heat from external sources; lower energy requirement

32

interstitial fluid

fills the space between vertebrate cells; provides nutrients necessary for diffusion

33

epidermis

outermost layer of skin; composed mostly of dead epithelial cells

34

dermis

supports the epidermis; contains hair follicles, glands, muscles, nerve, blood vessels

35

hypodermis

contains adipose tissue; includes fat cells and blood vessels

36

vasodilation

relaxes the muscles of the vessel walls causing an increase in diameter of superficial blood near surface

37

vasoconstriction

reduces blood flow and heat transfer by decreasing the diameter of superficial vessels

38

countercurrent heat exchange

heat in blood from artery core is transferred to vein blood returning from limbs

39

torpor

enables storage of energy; activity is low and metabolism decreases

40

estivation

summer torpor during extended high heat and scarce water
