Tissues Flashcards
4 types of tissue
- Epithelial
- Connective
- Muscle
- Nervous
Simple Epithelium
one layer of epithelial tissue
Type of simple Epithelium tissue
- simple squamous
- simple cuboidal
- simple columnar
- ciliated columnar
simple squamous
one layer of flattened cells
simple cuboidal
one layer of cube shaped cells
ciliated simple columnar
single layer of ciliated cylinder-shaped cells
simple squamous epithelial location
alveoli (air sacs in lungs)
simple squamous epithelial function
thinnest possible barrier to allow for rapid diffusion and filtration
simple cuboidal epithelial location
lining of the kidney
simple cuboidal epithelial function
forms secretory tissue of most glands and small glands
nonciliated simple columnar epithelial
single layer of cylinder-shaped cells
simple ciliated columnar epithelial function
secretion of mucin and movement of mucous along apical surface of epithelial by cilia
simple ciliated columnar epithelial location
lining of the larger bronchioles of the respiratory tract and uterine tubes
nonciliated columnar epithelial function
secretion of mucin
nonciliated columnar epithelial location
lining of most digestive tracts
ciliated pseudostratified columnar epithelium
single layer of cells with varying heights, all cells connect to the basement membrane, not all cells reach the apical surface
ciliated pseudostratified columnar epithelium function
protection, also involved in the movement of mucous across surface by ciliary action
ciliated pseudostratified columnar epithelium location
lining of the larger airways in the respiratory tract, including nasal cavity
stratified epithelium
two or more layers of cells
keratinized stratified squamous epithelium
multiple cell layers the base cells are cuboidal and the apical layer of cells are squamous
the top layer of cells are dead and filled with the protein keratin
keratinized stratified squamous epithelium location
epidermis of the skin
keratinized stratified squamous epithelium function
protection of underlying tissue from abrasion
nonkeratinized stratified squamous epithelium
multiple cell layers, base cells are cuboidal apical cells are squamous
nonkeratinized stratified squamous epithelium function
protection of underlying tissue from abrasion
