Four general types of tissue

epithelial tissues, connective tissues, muscle tissues, nerve tissues

Covering of body surfaces and internal organs, and lining, of body cavities

epithelial tissues

Major tossue component of glands

epithelial tissues

Always has a free surface and basement membrane

epithelial tissues

Lacks blodd vessels, so nourishment comes from the underlying connective tissue by diffusion movement

epithelial tissues

Number of layer of cells in epithelial tissue

simple and stratified

Means single layer

simple

Means multiple layer

stratified

Shape of the cells in epithelial tissues

squamous, cuboidal, columnar

Means flattened

squamous

Means cube-shape

cuboidal

Means elongated

columnar

Function: Lining body cavities pr glands, absorption secretion Location: Areas that require quick transport of materials, large amount of absorption and secretion

simple

Function: Lining, protecting areas of the body that meed more strength and resistance Location: Areast that require protection and strength

stratified

Cells appear stratified but every cell contacts basement

pseudostratified

Function and location: Lining absorption, secretion, creating curent across epithilium

pseudostratified

Function: Fast transport of molecules across cytoplasm, or protection in many layers Location: Areas that require rapid exchange of molecules or protection in many layers

squamous

Function: Relatively fast absorption and secretion Location: Some exocrine and endocrine glands, ducts

cuboidal

Function: Large amount of absorption and secretion Location: Lining of the intestine and respiratory tract

columnar

Number of layers and shape of the cells change based on distention of the organ

transitional epithelium

Function: Allowing distention and recp of an organ Location: Urinary bladder, ureter, calyces, urethra

transition epithelium

A single layer thin, flattened cells. Found in areas where diffusion or filtration occurs

simple squamous epithelium

Simple squampus epithelium lining blood vessels and heart is called

endothelium

Function: Rapid exchange of gas; small, lipid-soluble molecules; and fluid Location: luminal lining of vessels, lung alveoli, body cavity serous lining

simple squamous epithelium

A single layer of cube-shaped cells. Found in areas where secretion or absorption occurs

simple cuboidal epithelium

Function: Relatively quick absorption, secretion Location: kidney tubules, pancreatic acini, small ducts, thyroid follicles

simple cuboidal epithelium

A single layer of elongated cells. Designed for protection, secretion, or absorption

simple columnar epithelium

Funtion: Large amount of absorption, secretion, protection Location: lining and glands of majority of gastrointestinal tracts

simple columnar epithelium

Function: absorption, secretion, generation of current across the epithelium Locatipn: lining of fallopian tube

ciliated simple columnar epithelium

Single layer of columnar cells that appears to be multiple-layered because of its multiple-layered nuclei

pseudostratified columnar epithelium

Single layer of ciliated columnar cells, pther types of cells intermixed

ciliated pseudostratified columnar epithelium

Function: absorption, secretion, generation pf current across the epithelium Location: most of respiratory tract

ciliated pseudostratified columnar epithelium

Many layers of flattened cells. Cells at the bottom layers are the youngest and cuboidal- shapped, and will become flattened as they move upward tp higher layers.

stratified squamous epithelium

Thick layer of cells: cuboidal cells on basement membrane, flattened, eosinophillic, anuckeate cells on apical surface

keratinized stratified squamous epithelium

Function: protection from repeated, prolonged exposure to force and friction, preventing desiccation Location: skin

keratinized stratified squamous epithelium

Thick layer of cells: cuboidal cells on basement membrane: flattened but nucleated cells on apical surface

nonkeratinized stratified squamous epithelium

Function: protection from repeated, prolonged exposure to force and friction Location: oral cavity, esophagus, vagina, anal canal

nonkeratinized stratified squamous epithelium

Two or more layers of cuboidal cells

stratified cuboidal epithelium

Function: maintaining the shape and patency of duncts Location: interlobular and intralobular ducts

stratified cuboidal epithelium

More than one layer of polygonal cells dome cells: rounded, sometimes binucleate cells protruding out into the lumen on apical surface

transitional epithelium

Function: reducing number of layers and flattening the cells as the organ distends, then recoiling back to normal shape Location: lining of calyces, renal pelvis, ureter, urinary bladder, portions of urethra

transitional epithelium

Specialized to produce and secrete chemical substances into ducts or body fluids. Made pf cuboidal or columnar cells

glandular epithelium

Use ducts to secrete their products into an open space ( sweat glands, oil glands, salivary glands, and tear glands)

exocrine glands

Secrete their products(hormones) directly into blood or body fluids ( all Hormonal glands are endocrine glands)

endocrine glands

Function: forming protective layer against force, friction, desiccation Location: areas exposed to repeated and prolonged exposure to force, friction, and air

keratinization

Function: increasing surface area of the luminal border Location: areas that require large ampunt of absorption and secretion

microvilli

Function: generating movements to create current Location: areas that require movement of fluids over the epithelium

cilia

Function: increasing surface area for absorption, serving as mechanoreceptors Location: epididymis, specialized sensory epithelium

steriocilia
