What does Epithelial do
Covering
What does muscle tissue do
Contracting
What does neural tissue do
conducting
What does connective tissue do
Connect
Organs are composed of
two or more tissues
Only tissue with a free surface
epithelial
Epithelial with one layer
Simple
Epithelial with multiple layers
stratified
where is stratified tissue found
places susceptible to abrasion, such as skin
Simple epithelium
single layer of cells that all touch the basement membrane
stratified epithelium
multiple layers of cells
Transitional epithelium
special kind of epithelium that allows tissue to stretch and recoil
pseudostratified epithelium
all cells touch the basement membrane but grow to different heights
Superior View looks like a fried egg, side view is flat cells with flat nuclei
Simple Squamous
Square cells, nuclueus large and round, ring of cells
simple cuboidal
Tall, rectangular cells, oblong nucleus usually located in upper half of cell
Simple columnar
nuclei are scattered, columnar cells ciliated, every cell touches the base membrane, large goblet cells interspersed
Pseudostratified
When mulitple different cell types present in stratified epithelium, what cells classify the tissue
the type at the free surface
Stratified Squamous
Transition in cell shape from cuboidal or columnar cells in the lower region to flat cells on top
Three types of Muscle tissue
Skeletal, Cardiac, Smooth
Purpose of skeletal muscle
allows body skeleton to move
Cardiac Muscle purpose
pump blood through the vascular system
Smooth muscle purpose
control movement of materials
Skeletal Muscle Identification
Striations, multiple nuclei and long cells, cant see ends
