Chapter 4 (Connective tissue) Flashcards
basal surface
lower attached side, faces inward toward body
apical surface
upper free side, exposed to surface
simple epithelia
single layer thick
stratified epithelia
two or more layers thick and involved in protection
all epithelial tissues have 2 names
- number of cell layers (simple, stratified)
- shape of cell (squamous, cuboidal, columnar)
cell is named according to the shape in which layer
apical
squamous
flattened and scale-like
cuboidal
box-like, cube
columnar
tall, column-like
pseudostratified columnar epithelium
appears to be multi-layered and stratified, but it is single-layered simple
pseudostratified columnar epithelium example
respiratory epithelium in bronchi of the lungs
simple squamous epithelium example
alveoli in the lungs, lining of the heart
simple squamous epithelium
alveoli are thin air sacs that have to allow the exchange of gases such as carbon dioxide and oxygen
simple cuboidal epithelium
occurs in a lot of ducts and kidney tubules
simple cuboidal epithelium example
glands and ovaries
simple columnar epithelium
layer of closely packed cells in stomach to protect underlying tissues from stomach acid
simple columnar epithelium example
gastrointestinal tract
cilia
microscopic, hair-like structures or organelles that extend from the surface and help move things around
non ciliated example
simple columnar epithelium of the stomach is
ciliated example
simple columnar epithelium respiratory tract in the lungs is
(need to be able to move mucus and bacteria)
stratified squamous epithelium
usually occurs in transition areas between 2 other types of epithelia
nonkeratinized type
the moist linings of the esophagus, mouth, vagina
keratinized variety
forms the epidermis of the skin, a dry membrane
goblet cells are in
simple columnar epithelium in stomach
goblet cells are
mucus-secreting unicellular glands
order of naming
- ciliated or non ciliated
- simple or stratified
- shape
- goblet cells or no
which can be ciliated
only columnar
pseudostratified ciliated columnar epithelium example
lines the trachea, most of the upper respiratory tract
pseudostratified non ciliated columnar epithelium example
in males’ sperm-carrying ducts
