Exam 1 Part 4

Question 1

stratified cuboidal ET

Answer 1

2-3 layers; sweat and salivary glands

Question 2

stratified columnar ET

Answer 2

not common

Question 3

Transitional ET

Answer 3

similar to stratified squamous ET but surface cells rounded

capable of changing shape to allow for istention; urinary system (bladder + ureters)

Question 4

pseudostratified columnar ET

Answer 4

appears stratified but each cell contacts basement membranes; not all cells exposed
may be ciliated and associated with goblet cells that secrete mucus
in respiratory system cilia help move mucus/particles and direct to digestive system

Question 5

sensory epithelia

Answer 5

associated with nervous tissues

-connects to nervous cells

Question 6

Glandular epithelia

Answer 6

cell, tissue, or organ that produces and secretes a substance for use in or elimination from the body

Question 7

Gland

Answer 7

can be one cell or many

Question 8

Gland types

Answer 8

exocrine

endocrine

Question 9

exocrine gland

Answer 9

secrete products into ducts or to lumen of organ

-eventually goes outside body

Question 10

exocrine gland examples

Answer 10

salivary glands
pancrease (digestive enzymes)
sebacous -oils
mammary glands and sweat glands
goblet cells

Question 11

endocrine gland

Answer 11

secrete hormones directly into blood capillaries

stay with body

Question 12

endocrine gland examples

Answer 12

thyroid gland
adrenal gland
pancreas (insulin/glucagon

Question 13

glandular epithelia

Answer 13

cells doing the secreting

Question 14

Connective Tissue

Answer 14

most abundant tissue in body; very diverse
provides support -structurally and metabolically for other tissues
cells well separated -extensive matrix
capable of mitosis
most are highly vascularized

Question 15

CT functions

Answer 15

support
transport (blood)
protection
binding
fills space (fat)
storage (fat, bone (Ca2+))
insulation, cushions

Question 16

CT types

Answer 16

connective tissue proper
supportive connective tissue
fluid connective tissue

Question 17

Cell types in CT proper

Answer 17

fibroblasts

adipocytes

Question 18

fibroblasts

Answer 18

produces fibers in matrix
large, flat, branched
CT proper

Question 19

adipocytes

Answer 19

fat cells

CT proper

Question 20

Cell types in supportive CT

Answer 20

chondrocytes

osteocytes

Question 21

chondrocytes

Answer 21

mature cell of cartilage

Question 22

osteocytes

Answer 22

mature cell of bone

Question 23

blood cells

Answer 23

RBC, WBC (platelets)

some WBC leave the blood and wander tissues

Question 24

Matrix of CT can be

Answer 24

liquid
largely fibrous
solid

Question 25

Fibers of CT proper

Answer 25

collagen
elastic
reticular

Question 26

Collagenous fibers

Answer 26

protein called collagen
very tough, flexible, whitish, resist stretching
-ligaments, tendons, skin

Question 27

Elastic fibers

Answer 27

protein elastin
stretch and recoil, yellowish
ex. arteries, respiratory passages, skin

Question 28

reticular fibers

Answer 28

protein called reticulin
delicate, form network, not individually strong
ex. lymph nodes, spleen, liver

Question 29

ground substance

Answer 29

H2O, minerals, macromolecules
varies from viscious fluid to solid
surround/contains cells and fibers
NOT matrix

Question 30

CT =

Answer 30

ground substance + fibers + cells

Question 31

CT proper types

Answer 31

Loose
Areolar
Reticular

Question 32

loose CT

Answer 32

most general type, no regular arrangement
binds and packs tissues, connects skin and muscle (fascia) surrounds nerves and blood vessels
highly vascular
holds interstitial fluid
collagen and elastic fibers, fibroblasts, some immune cells
flexible in all directions

Question 33

adipose tissue

Answer 33

mostly adipocytes, few fibers
stores fat, cushions organs, insulates
organelles pushed to edges; appears empty, colorless
energy storage throughout body
