Term
How are they classified?
Definition
by appearance & function
Term
Most widespread tissue found in body?
Definition
Epithelial
Term
Where are Epithelial tissues found?
Definition
covers organs & lines body surfaces
Term
Functions of Epithelial tissues?

protection, secretion, absorption, excretion & sensory reception
Term
Simple squamous is best suited for?
And where is it found?
Definition
diffusion
lungs, blood/lymph vessels, body cavities
Term
Stratified squamous is best suited for? And where is it found?
Definition

protection

outer layer of skin, mouth, throat, vagina, anal canal

Term
Simple cuboidal functions in?
Definition
secretion & absorption in the kidneys and secretion in the glands
Term
Stratified cuboidal
Definition
Found in mammory glands, sweat glands, salivary glands, pancreas
Term
Advantage of several layers (stratified)?
Definition
greater protection
Term
What are often found with simple columnar epithelium?

goblet cells- produce mucus
cilia- move debris
Term
Where is simple columnar epithelium found?
Definition
Uterus, stomach, intestines
Term
What can be found in intestinal cells?
Definition
Microvilli- increases surface area & helps with absorption
Term
Where are pseudostratified epithelium found?
Definition
vas deferens, male urethra, pharynx
Term
Pseudostratified ciliated columnar epithelium & where found?
Definition
appear layered because of varying positions of nuclei but aren't
-found in respiratory tubes
Term
Transitional epithelium
Definition
changes shape--found in urinary bladder
Term
Exocrine glands
Definition
secrete products into ducts
Term
Endocrine glands
Definition
secrete into body fluids and blood
Term
Merocrine glands
Definition
release fluids by exocytosis (pancreas)
Term
Apocrine glands
Definition
loose portion of cell bodies during secretion (mammory glands)
Term
Holocrine glands
Definition
release entire cells (oil glands in skin)
Term
Connective tissues have...
Definition
good blood supply and extracellular matrix
Term
What is ECM?
Definition
basement membrane + interstitial matrix
Term
Fibroblast (C)
Definition

most common cell type, large & star-shaped

thin collagenous fibers
Term
Loose Connective (areolar)
Definition
binds parts together
Term
Adipose tissue
Definition
store fat-- beneath skin, around joints, padding kidneys and other organs
Term
Dense connective tissue
Definition
densely packed, strong but lacks good blood supply
(tendons & ligaments)

Definition
red & white blood cells & plasma
Term
What is the function of blood?
Definition
transports substances
Term
Skeletal muscles AKA
Definition
striated because they are striped
Term
Where are skeletal muscles found?
Definition
bone
Term
What do skeletal muscle cells look like?
Definition
cells are long so they are called fibers, several nuclei
Term
Where is smooth muscle found?
Definition
walls of internal organs, digestive tracts, blood vessels, bladder
Term
What do smooth muscle cells look like?
Definition
spindle-shaped, one nucleus
Term
Cardiac cells are connected to each other by what?
Definition
intercolated disks
create stripes so striated
Term
Two types of nervous tissue?
