Flashcards in Worksheet 4 Deck (30):
1

Epithelial Type 1

Duties- Protection, secretion and absorption
Ex- caers organs
lines hallow organs

2

Connective type 2

duties- provides support,binds,protection
Example- important in injury healing process
Flexible/ slight elastic
Fibroblasts- common type
dense/ ligaments connect to bone to bone

3

Muscle

made up of threaded like fibers when connected produce movement
Skeletal - found in muscles attach to bones
Smooth- involuntary contractions/ stomach
Cardiac- found only in the heart controlled involuntary

4

Nervous

Basic nerve called a neuron
Axons to other neurons found in brain/ spinal cord /neves
communicate with each other with muscles and glands

5

Fibroblasts

most common type of cell in connective tissue and produce new tissue fibers

6

Macrophages

Start as white blood cells and carry out

7

mast cells

found near blood vessels/ release blood heparih( prevent blood clotting )

8

Osteoblasts

cells with singular nuclei that synthesize bone

9

neorun

basic nene cell regulate many body functions

10

Phagocytosis

this is when a cell engulfs a solid

11

ligament

connect bone to bone

12

tendon

connect muscle to bone

13

connective tissue

provides support and protection of underlying structures/ in a gel like substance "healing"

14

membrane

thin sheet like structures
-madeup of epithlial and connective tissues/ 4 types of membranes
serars
mucous
cutaneous
synovizic

15

elastic

less strong but more flexible then collagenous fibers / found where flexibility is required

16

Synovial membrane

a thin membrane in freely moving joints that line the joint capsule and secretes synovial fluid

17

voluntary muscle contractions

is controlled by the central nervous system skeletal

18

involuntary muscle contractions

smooth muscle/ your body handles all as needed

19

melanin

a dark pigment that provides skin color
absorbs uv sunlight which prevents mutations in the dna and other damagins effects.

20

epidermis

skin/outer layer
made up of epithelial tissues plate like barrier

21

dermis

skin/ thicker then the epidermis
includes
connective tissues epithelial tissues/ smooth, nerves, blood

22

pili muscle -

when person is emotionally aroused or cold goose bumps muscle contracts so hair follicle becomes erect

23

Evaporative heat loss

cold water does not reduce core temp

24

acne

of inflamed or inflected sebaceas in the skin

25

psoriasis

a skin disease marked by red itchy scaly patches

26

Wart

a small hard caused by virus

27

Muscle tissues

Skeletal- voluntary
smooth involuntary
cardiac - involuntary

28

3 types of cartliage

Hayline cart- glassy found on end of bores
elastic- ears
fibrocartilage disks- thick pad like disks protection shock absorb

29

voluntary

allow you to move them

30

involuntary

you have control
