appendages

something that is attached

1

membrane

a thin sheet like structure that may have important functions in the body

2

cutaneous membrane

the primary organ of the integumentary system

3

serous membrane

a 2 layered epithelial membrane that lines the body cavities and covers the surface of organs

4

integument

refers to the skin

5

basement membrane

the connective tissue layer of the serous membrane that holdsand supports the epithelial cells

6

parietal portion

the part of the serous membrane that lines the walls of a body cavity

7

visceral portion

the part of the serous membrane that covers the surface of organs in the body cavities

8

pleura

the serous membranes in the thoracic cavities

9

peritonium

the serous membranes in the abdominal cavities

10

Pleurisy

a painful pathological condition characerized by inflammation of the serous membranes (pleura) tha tline the chest cavity and cover the lungs

11

mucous membrane

epithelial membranes that line body surfaces opening directly to the exterior

12

mococutaneous junction

the transitional area that serves a a point of "fusion" where skin and mucous membranes meet

13

synovial membrane

line the spaces between bones and joints that move are classified as connective tissue membranes

14

synovial fluid

helps reduce friction between the opposing surfaces of bones in moveable joints

15

bursae

small , cushionlike sacs found between moving body parts

16

sebaceous glands

oil glands

17

epidermis

the outermost layer of the skin

18

dermis

the deeper layer of the skin

19

Hypodermis or subcutaneous tissue

a thick layer of loose connective tissue and fat

20

stratum germinativum

the cells of the innermost layer of skin

21

keratin

a tough, waterproof material that provides cells in the outer layer of the skin with a horny, abrasion-resistant, and protective quality

22

stratum corneum

the tough outer layer of the epidermis

23

pigment

a substance that gives color to the skin

24

Melanin

the brown pigment

25

cyanosis

when oxygen levels decrease ofr if actual blood flow is reduced dramatically, the skin turns a bluish-gray color

26

dermal papillae

parallel rows of peg-like projections

27

follicles

specialized structures required for hair grown

28

lanugo

the hair of a newborn infant

29

hair papilla

a small cap-shaped structure of cells

30

root

the part of the hair hidden in the follicle

31

shaft

the visible part of the hair

32

arrector pilli

a smooth involuntary muscle attached to the base of a dermal papilla attached tothe base of a follicle

33

Meisserner's corpuscle

is located close to the skin surface, it detects sensations of light touch

34

Pacinian corpuscle

is located deep in the dermis; it is capable of locating pressure on the skin surface

35

sudoriferous gland

sweat glands

36

Eccrine sweat glands

more numerous, and widespread sweat glands. They make perspiration

37

Apocrine sweat glands

they secrete thicker secretion

38

Sebum

prevents drying and cracking of the skin

39

keratin

protects the body from excessive fluid loss
