Epithelial tissue histology labs Flashcards
function of stratified cuboidal epithelium?
protection, limited secretion and absorption
What type of tissue?
keratinized stratified squamous epithelium
What are two types of simple squamous epithelium?
endothelium- lines heart and blood vessels
mesothelium- protective membrane that covers the lungs, abdomen, heart and testes
identify tissue
nonciliated simple columnar epithelial tissue

keratanized stratified squamous epithelium
stratified cuboidal epithelium
stratified columnar epithelium
transitional epithelium
What are the usual functions of simple epithelium?
Simple epithelium is a single layer of cells that functions in diffusion, osmosis, filtration, secretion, or absorption.
Two types of pseudostratified columnar epithelium
nonciliated
ciliated
Two types of simple columnar epithelium
nonciliated
ciliated
What is the unique property of transitional epithelium?
It is stretchable
What are the two types of cells in this, what do they produce, and how can you tell them apart?
Light colored cells: mucous acini, produce mucous
Dark cells: serous acini, produce serous fluid
Where is transitional epithelium found?
ureter
lumen
stratified squamous epithelial
Where is ciliated simple columnar tissue found?

non keratinized stratified squamous
bowman’s space
What is the major sign of transitional epithelium?
Surface cells closest to the lumen have double nuclei

function of stratified columnar epithelium
protection and secretion
Where is ciliated pseudostratified columnar epithelium found?
the inside lining of the trachea and bronchi
function of ciliated simple columnar epithelium
in the respiratory tract cilia beat in unison to move foreign particles and mucus towards the throat where they can be coughed up or swallowed.
Four locations of simple squamous epithelium
blood vessels (endothelium), heart (endocardium), linings of the ventral cavities (mesothelium), and parietal layer of the bowman’s capsule of the kidney.
What is the reason for stratified epithelium?
protect underlying tissues in areas with considerable wear and tear.
apical surface
Where is keratinized stratified squamous epithelium found?
surface of the skin
What are the three arrangement types for cells in tissue?
simple, pseudostratified, and stratified
locations of stratified columnar epithelium
urethral lumen and conjunctiva of the eye
