one of the 5 ducts of the umbilical cord
label
in general, the lumens of blood vessels and lymphatic vessels are lined by a single layer of flat cells called
endothelium

simple columnar
have microvilli at apical border to increase surface area
what
gallbladder
lumen lined by simple columnar
have microvilli to increase surface area
what can increase surface area
microvilli- border of intestine, and kidneys
sterocilia- border of epididymis
fingerlike projections into the lumen that increase surface area
villi and stereocilia
common places for pseudostratified columnar epithelium
trachea and epididymis

stereocilia
type of microvilli that increases surface area
what holds stratified squamous epithelium together
intercellular bridges
These spine-like cytoplasmic processes (known as tonofilaments, which are a type of intermediate filament) anchor back to the desmosomes (not viewable) within the cell, helping to link the cells together
Finger-like projections of pale, pink ___ (loose connective tissue) extend up to the epithelium of the skin.
papillae
esophagus
lip of dog
keratinized stratified squamous epithelium connected by intercellular bridges
what
planum nasolabiale cow

what is the long pink projection
the planum nasolabiale,
stratified squamous epithelium have lost their nuclei at surface where cells have become keratinized
papillae (loose connective tissue)
special epithelium is layered, non-absorptive, stretchable, and found primarily in the urinary passages.
transitional epithelium
transitional epithelium
The apical cells can be either ___ or ____ depending on the degree of distention of the lumen.
flat or ballon shaped
When the lumen is full (i.e., with urine), the epithelium stretches and distends, causing the cells to flatten. When the lumen is empty, the cells become more cuboidal or balloon-shaped.
top cells are flat therefore the lumen is ___
full of urine
transitional cells of ureters of horse
urinary bladder
