Lab 7 Tissues

Question 1

epithelial tissue

Answer 1

• protect tissues underneath
• selectively permeable membrane
• sensory surface

Question 2

simple epithelium

Answer 2

one layer
- squamous are irregular and flat. line lungs

cuboidal and columnar: cubes and columns. link GI tract and ducts. have cillia

Question 3

stratified epithelium

Answer 3

multiple layers

- upper layer is squamous, middle is cuboidal and basal is columnar

Question 4

glandular epithelium

Answer 4

• highly modified epithelial cells.

- line liver, mammary glands, pancreas

Question 5

pseudostratified

Answer 5

appear stratified but are simple based on arrangements

found in respiratory system

Question 6

loose connective tissue

Answer 6

a mass of proteins that form a ground substance (ex. collagen, elastin, reticulin, macrophages, adipose tissue)

Question 7

reticulin (LCT)

Answer 7

thin branch fibre that supports glands and junctions between tissues (Loose connective)

Question 8

macrophage (LCT)

Answer 8

small round cells that are immune first response (loose connective)

Question 9

adipose tissue (LCT)

Answer 9

contain fat. have nucleus but it is squished to the side

Question 10

dense connective tissue

Answer 10

tightly packed collagen fibers, pretty strong

Question 11

SPECIAL connective tissue

Answer 11

blood cells: plasma has the cells
cartilage
bone

Question 12

erythrocytes

Answer 12

rbc

Question 13

leukocytes

Answer 13

WBC

Question 14

plateletes

Answer 14

bone marrow cells

Question 15

cartilage

Answer 15

matrix of chondrin and collagen secreted by chondrocytes

Question 16

chondrocytes

Answer 16

secrete chondrin for cartilage and reside in cavities called lacunae

Question 17

bone

Answer 17

bone cells are osteocytes. form in concentric layers called lamellae. Haversian canals in the middle

Question 18

haversial canals

Answer 18

surround blood vessels and nerve cells through bone and co,,tunicate through Canaliculi

Question 19

muscle tissue

Answer 19

made of actin and myosin. bundles of these are called myofibrils

Question 20

types of muscle

Answer 20

skeletal. cardiac and smooth

Question 21

cardiac muscle

Answer 21

HAS INTERCALATED DISKS THAT ORGanize them into fibres

• these form channels to have electrical signals to move
• also branched (only type of muscle to have this)
• has fewer nuclei than skeletal

Question 22

nervous tissue

Answer 22

contain neurons, and support cells called glial AKA Schwann cells

Question 23

neuron parts

Answer 23

cell body with nucleus, dendrites are extensions, axons carry nerve impulses to the axonal end to release neurotransmitters

Question 24

Basement membrane

Answer 24

a protein layer epithelial cells sit on

ALWAYS

Question 25

microvilli onto of columnar cell

Answer 25

stomach

Question 26

flagella onto of columnar cell

Answer 26

sperm

Question 27

fibroblasts

Answer 27

Loose and dense connective tissue consist of cells called fibroblasts that make connective tissue fibers - make collagen, elastin, reticulin

Question 28

lung tissue

Answer 28

looks empty but here, there are lots of alveoli that are lined by simple, squamous epithelium

Question 29

reticular tissue

Answer 29

very corky in elasticity

Question 30

Granulocytes

Answer 30

cAN see granules Neutrophil, Eosinophil, Basophils

Question 31

Neutrophil

Answer 31

neutral staining, most numerous

Question 32

Eosinophil

Answer 32

usually rare unless there is an infection. acid staining, kills nematodes

Question 33

basophils

Answer 33

basic staining, turn into mast cells involved in inflammation

Question 34

Monocytes

Answer 34

macrophage. digest and engulf bacteria.

Question 35

Lymphocytes

Answer 35

make antibody, help macrophages, kill specific target cell

Question 36

Erythrocytes

Answer 36

red blood cells filled with hemoglobin

Question 37

Platelets

Answer 37

cell fragments used in clotting

Question 38

osteon

Answer 38

a circle of bone tissue

Question 39

hyaline cartilege

Answer 39

found in joints. most present in body

Question 40

elastic cartilege

Answer 40

found in ear and nose

Question 41

fibro cartilege

Answer 41

found in skull. strongest kinds of fibers

Question 42

smooth muscle

Answer 42

has tapered ends <0> | - one central nuclei

Question 43

skeletal muscle

Answer 43

has striations. lots of nuclei and mitochondria

Question 44

simple squamous epithelium

Answer 44

one layer, minimal barrier to diffusion, line lungs, kidneys and major cavities. associated with movement of minerals

Question 45

simple cuboidal and columnar epithelium

Answer 45

line respiratory and intestines, secrete fluid
