Simple Epithelial Tissues Vocabulary/Questions
What is the function of epithelial tissue?-✔✔ Lining tissue that forms
boundaries with environment. Protect, absorb, filter, secrete
What structures do all epithelial tissues share?-✔✔ Top surface is called
free surface or apical surface. Bottom = basal surface, membrane under
basal is basement membrane. All of these are avascular. Classified by
number of layers and shape.
How do simple and stratified epithelial tissues differ?-✔✔ Simple epithelial
tissues have only one layer of cells while, while stratified epithelial have
more than one layer.
Simple squamous epithelium-✔✔ Single flat layer of cells that is
permeable. Rapid diffusion of materials found in blood vessels and lung
tissue.
Simple cuboidal epithelium-✔✔ single layer of cube shaped cells. Function
is to secrete and absorb. Found in tissues of kidney.
simple columnar epithelium-✔✔ Single layer of tall closely packed cells.
May have cilia and goblet cells that secrete mucus. Function is to secrete
mucus for protection. Found in lining of digestive tract.
stratified squamous epithelium-✔✔ Thick layers provide protection. Found
in epidermal layers of skin
stratified cuboidal epithelium-✔✔ More than one layer of cuboidal cells.
Rare in body. Found in salivary + mammary glands.
What is pseudostratified epithelium?-✔✔ Cell nuclei are found at different
levels. Appears stratified but isn't. Function is to secrete and absorb. Found
in upper respiratory tract
