-
what is the study of tissue
histology
-
what are the four basic tissue
epithelial, connective, muscle, neural
-
what tissue cover exposed surfaces and internal cavities and passageways
epithelial
-
what tissue often contains secretory or gland cells, scattered among other cell types
epithelial
-
what tissue are derived from epithelia but more secretory cells
glands
-
which gland secretes on external areas
exocrine gland
-
which gland secretes hormones into interstitial fluid
endocrine gland
-
what tissue provides physical protection, control permeability, provide sensation, and produce specialized secretions
epithelial
-
what feature of the epithelial tissue faces exterior and internal space
apical surface
-
what feature of the epithelial tissue has microvilli often found on cells of digestive, urinary, and reproductive tracts
apical surface
-
what feature of the epithelial tissue has cilia often found on cells lining respiratory and some parts of the respiratory tract
apical surface
-
what feature of the epithelial tissue faces lumen (space) when lining hollow organs
apical surface
-
what feature of the epithelial tissue is attached to adjacent tissues, and have membraneous organelles comparable to other cell types
base
-
what feature of the epithelial tissue include base and lateral surface (attached to neighboring cells)
basolateral surfaces
-
what are the three epithelial shapes
squamous (thin and flat) cuboidal (small boxes) columnar (slender rectangles)
-
what is the single later and double layer in epithelial cells called
simple and stratified
-
what epithelial cells are made of peripheral and transmembrane proteins
hemidesmosomes
-
what epithelial cells are deepest attached
basal lamina
-
what basal lamina contains glycoproteins and fine protein filaments
clear layer (lamina lucida)
-
what basal lamina contains bundles of coarse protein fibers, gives strength and restricts diffusion
dense layer (lamina dense)
-
what intercellular attachments form barrier that prevents lumen contents from getting past cells
occluding junctions
-
what intercellular attachments adjacent plasma membranes tightly bound with proteins
occluding junctions
-
what intercellular attachments attaches terminal webs of adjacent cells
adhesion belt
-
what intercellular attachments reinforces occluding junctions
adhesion belt
-
what intercellular attachments has dense protein band surrounding cell
adhesion belt
-
what intercellular attachments permits chemical communication to coordinate activates of adjacent cells
gap junction
-
what intercellular attachments is formed by interlocking junctional proteins (connexons), ciliated epithelial tissue, cardiac muscle tissue
gap junction
-
what intercellular attachments interlock cytoskeletons of adjacent cells, very strong
desmosomes
-
what intercellular attachments formed by cell adhesion molecules and intercellular cement
desmosomes
-
what epithelial cell is this and flat, irregularly shaped
simple squamous
-
what epithelial cell is found in protected regions, where absorption and diffusion takes place
simple squamous
-
what epithelial cell is along kidney passages, inside eye, alveoli of the lung
simple squamous
-
what epithelial cell has a slippery surface reduces friction, lining ventral body cavity, lining heart and blood vessels
simple squamous
-
what epithelial cell is located where mechanical or chemical stresses are severe, series of layers
stratified squamous
-
what epithelial cell is in skin, mouth, throat, esophagus, rectum, anus, vagina
stratified squamous
-
what are the two types of stratified squamous cells
keratinized and nonkeratinized
-
what type of stratified squamous is tough and water resistant found at surface of skin
keratinized
-
what type of stratified squamous is resistant abrasion but can dry out and found in oral cavity, pharynx, esophagus, anus, vagina
non-keratinized
-
what epithelial cell resemble hexagonal boxes with nucleus in center
cuboidal epithelial
-
what are the two types of cuboidal epithelium
simple and stratified
-
what cuboidal epithelium lines exocrine gland and ducts, portions of kidney, secretory chambers of thyroid gland
simple cuboidal
-
what cuboidal epithelium is rare, in ducts of various exocrine glands
stratified cuboidal
-
what epithelial cell is ususally stratified epithelium that stretches and recoils
transitional epithelium
-
what epithelial cell is located in urinary bladder, urethra, and urine-collecting chambers of kidneys
transitional epithelium
-
what epithelial cells appear rectangular in sectional view
columnar epithelium
-
what epithelial cell is enlongated nuclei near basal lamina
columnar epithelium
-
what type of columnar epithelium is located in the stomach, intestine, uterine tubes, and kidney ducts
simple columnar
-
what type of columnar epithelium is located in nasal cavities, trachea, and larger airways of lungs
pseudostratified columnar
-
what epithelium varies in cell shape and functions, cells typically possess cillia
pseudostratified columnar
-
what epithelium has nuclei located at different areas of cells, so appears stratified; every celll attached to basal lamina

stratified columnar
-
what epithelium is relatively rare, either two or multiple layers, columns appear on superficial cells
stratified columnar
