Chapter 4

test thursday- 17th

Epithelium slide

hemidesmosomes- bottom

desmosomes- sides

tight junctions- top sides

adheron- sides, on contracting muscles

gap junctions- space between nervous, and muscle tissue

dermis and or connective tissue- can bleed

junctions have to disconnect and form new junctions in transitional epithelium tissue

Master notes page3- in microscope piece you will only see apical view of simple squamous, but in a photograph it can be on either side

simple squamous- looks like fish eggs

cuboidal- how to find it, find lumen, find shape, find # of layers

Columnar- find lumen, find shape, is it ciliated, then # of layers

pseudostratified- (called pseudostratified/ silliated or non/ columnar) - on the microscope it will only be ciliated, but in the pictures it can be either

page 5 bottom/ 6 top- goblet cells- can only be in columnar, so once you see know its columnar

PAGE 7 TOP- when doing practicum, when seeing stratified squamous thats keratinized, the bottom has to be dense irregular

page 7- bottom, might be mistaken as transitional

the outer layer of stratified anything doesn’t have to match the inner layer

PAGE 9- this is what strafified columnar looks like

page 10- top imaage is usally confused with squamous- you know its transitonal because the nucleai are NOT flat

Connective tissue

LOOSE:

color matters: pink

Areolar- first row, looks like thread and needles, going to be magenta

adipose- shcok absorve store energy; looks like the apical view of simple squamous however the DIFFERENCE is nucleous is on the edge. Looks like bbbles

reticular- colors pink, magenta, blac, looks like branches

DENSE:

irregular- looks like mixing pain/ scheeta

regular- looks like ramen, pink & white, or yellow and white

elastic CT, looks like bacon or lasagna

CARTILAGE:

hayline- have large lacunae

elastic- have big lacunae but has fibers that look like eyelashes

fibrocartilage- small lacunae, comes in small groups

OSSEOUS:

bone- looks like tree ring

Blood/ lypmth:

blood cells- looks like cherreos

muscle tissue

Smooth muscle- mistaked for dense regular, or dense irregular. It has more structure than dense irrelgular but less than regular

Cardicac- striated, looks like steak

skeletal- looks like fish, striated

Nervous tissue:

neuron- you will only see this in pictures
