Front 1

primary tissues

Back 1

epithelial, connective, nervous and muscular

Front 2

matrix (extracellular material)

Back 2

material surrounding the cells and composed of the fibrous proteins and ground substance

Front 3

fixative

Back 3

a chemical like formalin that prevents decay and makes the tissues more firm

Front 4

stains

Back 4

enhances detail

Front 5

longitudinal section

Back 5

tissue cut in the long direction

Front 6

cross section (transverse section)

Back 6

tissue cut perpendicular to the longitudinal section

Front 7

oblique section

Back 7

cut in between the longitudinal and cross sections, at an angle

Front 8

smear

Back 8

the tissue is rubbed or spread across the slide rather than sliced

Front 9

spread

Back 9

the tissue is laid out on the slide; placing a small square of tissue paper or tuft of lint on a sheet of glass

Front 10

epithelium

Back 10

type of tissue composed of one or more layers of cells either covering an organ surfaceor forming the secretory tissue and ducts of a gland

Front 11

basement membrane

Back 11

between the epithelium and the connective tissue

Front 12

simple squamous

Back 12

thin flat scaly cells

Front 13

simple cuboidal

Back 13

square or round cells

Front 14

simple columnar

Back 14

tall narrow cells

Front 15

pseudostratified columnar epithelium

Back 15

not all cells reach the free surface and the taller cells cover the shorter ones

Front 16

goblet cells

Back 16

produce protective mucous over the mucous membranes

Front 17

stratified epithelia

Back 17

range from 2-20 layers and only the deepest layer reaching the basement membrane

Front 18

stratified squamous

Back 18

two kinds- keratinized and non-keritinized and are flat multi-layered cells

Front 19

stratified cuboidal

Back 19

multi-layered square or round cells

Front 20

stratified columnar

Back 20

rare but found in the pharynx, larynx, anal canal and male urethra

Front 21

keratinized

Back 21

found on the skin surface, which are alive and covered with a layer of compact dead squamous cells

Front 22

non-keratinized

Back 22

lackes the surface layer of dead cells. Are exfoliated and dead.

Front 23

connective tissue

Back 23

ususally occupy less space and fall into 3 categories: fiborous ct, supportive ct, and fluid ct

Front 24

fibers

Back 24

3 types of protein fibers: collagenous fibers made of collagen, reticular and are thin fibers coated with glycoprotein and elastic and made of elastin able to stretch and shrink back to small size

Front 25

fiborous ct

Back 25

two types: loose and dense

Front 26

loose ct

Back 26

areolar, reticular and adipose tissue and there is much space occupied by ground substance

Front 27

dense ct

Back 27

the fibers occupy more space than the cells and ground substance. There is regular and irregular

Front 28

regular dense ct

Back 28

the collagen fibers are closely packed and leave relatively little open space and the fibers are parallel to each other

Front 29

irregular dense ct

Back 29

thick bundles of collagen and little room for cells and ground substance but the collagen bundles run in different directions

Front 30

reticular tissue

Back 30

mesh of reticular fibers and fibroblasts and forms the structural framework of organs and tissues like lymph nodes, spleen, thymus, and bone marrow

Front 31

adipose tissue

Back 31

adipocytes are the dominant cell and may occur singly or in small clusters in areolar tissue

Front 32

cartilage

Back 32

supportive connective tissue with a flexible rubbery matrix and gives shape to external ear

Front 33

chondroblasts

Back 33

secrete the matrix and surround themselves with it until they become trapped in little cavities called lacunae and when they are enclosed here are called chondrocytes

Front 34

hyaline cartilage

Back 34

clear and glassy appearance

Front 35

elastic cartilage

Back 35

conspicuous elastic fibers

Front 36

fibrocartilage

Back 36

coarse and readily visible bundles of collagen

Front 37

perichondrium

Back 37

dense irregular connective tissue that surrounds the elastic cartilage and most hyaline cartilage

Front 38

osseous tissue

Back 38

makes up most of the mass of a bone

Front 39

spongy bone

Back 39

fills the heads of long bones

Front 40

compact (dense) bone

Back 40

more dense calcified tissue with no spaces visible to the naked eye

Front 41

central canal

Back 41

run longitudinally through the shafts of long bones like the femur

Front 42

lamellae

Back 42

onionlike layers around each central canal

Front 43

osteon

Back 43

central canal and its surrounding lamellae

Front 44

osteocytes

Back 44

mature bone cells

Front 45

canaliculi

Back 45

delicate canals and radiate from lacunas to its neighbors and allows osteocytes to contact each other

Front 46

blood

Back 46

liquid connective tissue that travels through tubular vessels and transports cells and disolved matter from place to place

Front 47

plasma

Back 47

ground substance of which is linked with blood

Front 48

formed elements

Back 48

cells and cell fragments

Front 49

erythrocytes

Back 49

red bloos cells

Front 50

leukocytes

Back 50

white blood cells

Front 51

platelets

Back 51

small cell fragments scattered amid the red blood cells and are involved with clotting and other mechanisms for minimizing blood loss
