Anatomy Test 2- BIOL 2220 Clemson
Questions With Complete Solutions
Tissues are classified by number of layers
simple layers single layer
stratified layers more than one layer
pseudostratified layers one layer (looks like more)
simple function absorption and filtration
stratified function protection
simple epithelium found areas without much friction
stratified epithelium found areas with high abrasion
, Anatomy Test 2- BIOL 2220 Clemson
Questions With Complete Solutions
Pseudostratified epithelium found areas with little movement
Different shapes of epithelium squamos, cuboidal, columnar, transitional
squamos epithelium is (shape) flat
cuboidal epithelium is (shape) cube, same width and length
columnar epithelium is (shape) column, longer than wide
transitional epithelium is (shape) dome cells on apical surface , can change shape
(stretch), found in hollow storage organs
Functions of Epithelium 1. establish boundaries
2. protection
3. absorption
4. filtration
, Anatomy Test 2- BIOL 2220 Clemson
Questions With Complete Solutions
5. excretion
6. secretion
7. sensory reception
2 groupings of epithelial tissue 1. covering and lining
2. glandular
covering and lining epithelium found on all free body surfaces, exposed to the exterior..
ex. lining the digestive and respiratory tract
apical layer exposed to air, free surface
basal layer attached surface, usually attached to an underlying CT
surface meaning simple/single cells
layers meaning stratified cells

Questions With Complete Solutions
basement membrane composed of two parts: basal lamina and reticular lamina
where is the basement membrane located? basal surface of epithelial tissue
basal lamina noncellular sheet of glycoproteins, anchors basal layer to connective tissue
reticular lamina collection of collagen fibers, adds strength and integrity to the basement
membrane
What connects epithelial and connective tissue? basal layer - glycoproteins and collagen
Does epithelial or connective tissue have blood vessels? connective tissue
Are epithelial cells vascular or avascular? avascular (no blood vessels)
