Lab - Chapter 4 Tissue Level of Organization Flashcards
4 Tissue types _______ Epithelial, Connective, Muscle and Nervous
A
Epithelial tissue forms skin, lines digestive system, urinary tract _______ all passageways that communicate with the outside
And
Epithelial tissue function _______ physical protection, control permeability, provides sensation and produce secretions
Is
Sensory cells are contained _____ Neuroepithela
In the
Glandular Epithelial Cells 2 functions ______ discharge secretions and release into Interstial fluids or blood
Are
Epithelial Polarity _____ structure, internal space and the difference between exposed and attached surfaces
Is
Exposed Epithelial _____ Apical surface Microvilli
Is
Mitochondria concentrated near the base of the cell _____ for high energy use
is
Cellularity _____ Cells bind close together
Is
The base of Epithelium _____ a bound non cellular membrane
has
Avascularity _____ without vessels
is
Damaged cells _____ constantly replaced
are
Apical Surface Cells ______ exposed cells
are
Basolateral Surface Cells _____ the base and attachments
are
Ciliated Epithelium have 250 cilia that beat ____ unison
in
Intercellular connections _____ firmly attached transmembrane proteins
Are
Transmembrane Proteins ______ called “Cell Adhesion Molecules”
Are
Cell Junctions _____ special attachment Points
Are
Cellular Gap Junction _____ 2 cells held together by interlocking cell proteins
is
Tight Cellular Junction _____ Lipids tightly bound together
is
Demosomes ______ Strong playable cells that can endure twisting and stretching
Are
Epithelial cells must ___ attached or they will die
be
Cellular repair can be ____ daily basis
On a
Simple Epithelium ___ only one layer attached at the base
Is
Stratified Epithelium ____ several layers in exposed areas
Is
Simple Squamous ____ most delicate and is for absorption and diffusion in lungs or cavity lining
Is
Stratified Squamous _____ used where stresses are
Are
Two kinds of Stratified Squamous Cells, Keratinized (outer surface) _____ Non Keratinized (inner surface like oral cavity or anus)
And
Cuboidal Epithelial _____ square shaped and same size
Is
Simple Cuboidal ____ used for limited absorption or secretion
Is
Stratified Cuboidal _____ Rare
Is
Transitional Epithelial ____ Stratified cells that can change from Squamous to Cuboidal
Is
