chapter 4 part 3 epithelium

Question 1

connective tissue

Answer 1

protect, support and bind organs
-RBC, WBC and platelets included

Question 2

fat

Answer 2

conenctive tissue that stores energy

Question 3

tissue development

Answer 3

4 tissue develop from the three primary germ layers

Question 4

epithgelial tissue

Answer 4

forms from all 3 germ layers
-have free apical surface and an attached basal surface

Question 5

connective tissue and muscular tissue

Answer 5

form from mesoderm

Question 6

nervous tissue

Answer 6

form from ectoderm

Question 7

epithelial basal layer

Answer 7

secretes the basal lamina

Question 8

basal lamina

Answer 8

underlying connective tissue that secretes the reticular lamina
-both basal and reticular lamina form a noncellular basement membrane on which the epithelium sits

Question 9

naming epithelium

Answer 9

-always names based on the shape of cell in the apical (outermost) layer

Question 10

serous membrane

Answer 10

-made of simple squamous epithelium
-lines inner walls of body cavities
-secrete serous fluid for lubrication and movement

Question 11

simple cuboidal

Answer 11

-lines kidneys and glands

Question 12

goblet cells

Answer 12

-columnar cells that have differentiated to be able to secrete mucous
-simple columnar
-in ciliated tissue

Question 13

statified squamous

Answer 13

-has apical surface made of flat cells
-the many layers protect against strong friction forces
-outer layer of the skin

Question 14

stratified cuboidal

Answer 14

-has apical surface
-2 or more layers of cells
-sweat glands and urethra
-1 layer would not be enough for the functions it does

Question 15

stratified columnar

Answer 15

very rare

Question 16

transitional

Answer 16

-has an apical surface
-not stretched= empty bladder
-flat cells= full bladder

Question 17

pseudostratified ciliated

Answer 17

upper respiratory tract

Question 18

endothelium

Answer 18

specialized simple squamous epithelium that lines the entire circilatory system and makes blood flow easy
-from mesoderm (middle layer)

Question 19

mesothelium

Answer 19

found in serous membranes like the pericardium, pleura and peritoneum
-from mesoderm (middle layer)

Question 20

endothelium and mesothelium

Answer 20

-the only epithelial tissue from the third germ layer

Question 21

extracellular matrix

Answer 21

help cells attach and communicate with one another
-affects cell growth, movement, and repairs damaged tissues
-it is secreted by cells/ surrounds them in tissue
-secretions specific to tissue

Question 22

molecules that make up the extracellular matrix

Answer 22

-adhesive proteins, structural proteins and proteoglycans
-can also have fibers, salts, water and dissolved macromolecules

Question 23

functions of epithelia

Answer 23

-passage of substances at cells lining the air sacs in the lungs and the nephrons in the kidney
-secreting substances in the pancreases
-absorbing in digestion

Question 24

stratified epithelium

Answer 24

-regenerate from below
-all about protection
-named based on the shape of the cell at the apical layer

Question 25

stratified squamouos

Answer 25

-the deep layers of the cells may appear cuboidal or columnar
-the ticket epithelial tissue for protection
-keratinized (protective protein) is for the epidermis

Question 26

non keratinized statified squamous

Answer 26

forms the moist lining of body organs (esophagus, mouth, vagina)

Question 27

gland

Answer 27

one or more cells that make and secrete an aqueous fluid
-2 types
-endocrine and exocrine

Question 28

endocrine glands

Answer 28

have no contact with the exterior body and produce hormones

Question 29

how are exocrine glands classified?

Answer 29

by their structure or method of secretion

Question 30

goblet cells are?

Answer 30

unicellular exocrine glands

Question 31

examples of multicellular glands?

Answer 31

-sweat, oil, pituitary and adrenal glands

Question 32

simple exocrine glands

Answer 32

ducts with few branches

Question 33

pancrease/ compound gland

Answer 33

compound exocrine gland that has ducts that end in tubiles or sac like structures

Question 34

aveoli/ compound gland

Answer 34

ducts end in simple sacs

Question 35

lateral surface features

Answer 35

-tight junctions, desmosomes and gap junctions
