tissues

Question 1

What do epithelial tissues do?

Answer 1

Form lining on surface of internal and external surfaces
Single layer of constantly dividing cells (Stem cells)
High turnover rate (sloughing off)
Basement membrane of connective tissue for support and adhesion

Question 2

characteristics of epithelial tissues

Answer 2

Highly innervated
Poorly vascularized
High rate of regeneration and migration
Secretion of cell products (mucus, lubricant, enzymes, pigments)
Microvilli, cilia

Question 3

whats an ulcer?

Answer 3

erosion of the epithelium

Question 4

simple squamos cells

Answer 4

lines blood vessels and air sacs of lungs. permits exchange of nutrients waste and gases

Question 5

simple cuboidal

Answer 5

lines kidneys, tubules and glands. secretes and reabsorbs water and small molecules.

simple columnar

Answer 6

lines most digestive organs. absorbs nutrients and produces mucus.

Question 7

stratified squamos

Answer 7

outer layer of skin, mouth, VAGINA. protects against drying out, infection and abrasion

Question 8

stratified cuboidal

Answer 8

lines ducts of sweat glands. secretes water and ions.

Question 9

stratified columnar

Answer 9

lines epididymus, mammary glands and larynx. secretes mucus

Question 10

glands

Answer 10

subunits of epithelial tissues

Question 11

secretory epithelia

Answer 11

Invaginated layers continuous with surface epithelia
New cellular functions (secretion of cell products (hormones, enzymes, fluids)
Supported by underlying connective tissues

Question 12

what does connective tissue produce?

Answer 12

it produces extracellular matrix

Question 13

what is the bulk of your body made up of?

Answer 13

connective tissue

Question 14

what do you need to make collagen?

Answer 14

vitamin C

Question 15

characteristics of connective tissue

Answer 15

Structure and support 
Low rate of cell replication
Highly vascularized
Production of Extracellular Matrix (ECM)
Multiple cell types
Multiple types of structural components

Question 16

fibrous connective tissue

Answer 16

Collagen and Elastin

Question 19

solid connective tissue

Answer 19

bone

Question 20

collagen characteristics

Answer 20

Ropelike, high tensile strength, flexible
Helical protein subunits
Random matrix or organized bundles
Most common protein in the body
Adhesive, structural

Question 21

ground substance characteristics

Answer 21

Flexible filler materials (rubbery)
Hydroscopic: absorb water
Molecules comprised of sugar and protein chains (proteoglycans)
GAG’s (glycosaminoglycans)
Glucosamine sulphate, Condroitin sulphate
Hyaluronic acid, Lubracin

compression

Answer 23

axial squeezing

Question 24

shear

Answer 24

tangential slicing

Question 25

torsion

Answer 25

axial twisting

Question 26

human structures are generally considered

Answer 26

viscoelastic

Question 27

Wolfs Law

Answer 27

structural bone reflects the pressures acting on it

Question 28

stress fracture

Answer 28

stressing the bone faster than it can be repaired.

Question 29

epidermis

Answer 29

Basal and stratified epithelial layers with Melanocytes

Question 30

dermis

Answer 30

Fibrous connective matrix with muscles, glands, hair follicles, blood vessels, nerves

Question 31

hypodermis

Answer 31

Fascia, adipose, vessels, nerves

Question 32

factors contributing to pigmentation

Answer 32

Melanosomes in Basal layer produce Melanin. (brown protein pigment) Genetic baseline production Modified by environmental factors

Question 33

signs of malignant melanoma

Answer 33

``` Assymetry Border that’s irregular Color that’s uneven Diameter bigger than a pea Evolving shape ```
