UPDATED Exam Questions and
CORRECT Answers
Tissues are classified by - CORRECT ANSWER - number of layers



simple layers - CORRECT ANSWER - single layer



stratified layers - CORRECT ANSWER - more than one layer



pseudostratified layers - CORRECT ANSWER - one layer (looks like more)



simple function - CORRECT ANSWER - absorption and filtration



stratified function - CORRECT ANSWER - protection



simple epithelium found - CORRECT ANSWER - areas without much friction



stratified epithelium found - CORRECT ANSWER - areas with high abrasion



Pseudostratified epithelium found - CORRECT ANSWER - areas with little movement



Different shapes of epithelium - CORRECT ANSWER - squamos, cuboidal, columnar,
transitional


squamos epithelium is (shape) - CORRECT ANSWER - flat

,cuboidal epithelium is (shape) - CORRECT ANSWER - cube, same width and length



columnar epithelium is (shape) - CORRECT ANSWER - column, longer than wide



transitional epithelium is (shape) - CORRECT ANSWER - dome cells on apical surface ,
can change shape (stretch), found in hollow storage organs


Functions of Epithelium - CORRECT ANSWER - 1. establish boundaries
2. protection
3. absorption
4. filtration
5. excretion
6. secretion
7. sensory reception


2 groupings of epithelial tissue - CORRECT ANSWER - 1. covering and lining
2. glandular


covering and lining epithelium found - CORRECT ANSWER - on all free body surfaces,
exposed to the exterior.. ex. lining the digestive and respiratory tract


apical layer - CORRECT ANSWER - exposed to air, free surface



basal layer - CORRECT ANSWER - attached surface, usually attached to an underlying
CT


surface meaning - CORRECT ANSWER - simple/single cells

,layers meaning - CORRECT ANSWER - stratified cells



basement membrane composed of two parts: - CORRECT ANSWER - basal lamina and
reticular lamina


where is the basement membrane located? - CORRECT ANSWER - basal surface of
epithelial tissue


basal lamina - CORRECT ANSWER - noncellular sheet of glycoproteins, anchors basal
layer to connective tissue


reticular lamina - CORRECT ANSWER - collection of collagen fibers, adds strength and
integrity to the basement membrane


What connects epithelial and connective tissue? - CORRECT ANSWER - basal layer -
glycoproteins and collagen


Does epithelial or connective tissue have blood vessels? - CORRECT ANSWER -
connective tissue

vessels)


Where is covering and lining epithelial tissue located? - CORRECT ANSWER - all free
body surfaces (mouth to anus)


glandular epithelium - CORRECT ANSWER - secretory part of a gland, secretes things



gland definition - CORRECT ANSWER - cell or group of cells of specialized epithelium
that secrete substances into ducts, onto surfaces, or into the blood

, ducts - CORRECT ANSWER - tubules that direct to a specific place



are glands unicellular or multicellular? - CORRECT ANSWER - both


A gland requires this to produce its mostly watery secretory product - CORRECT
ANSWER - energy

Most exocrine glands are associated with - CORRECT ANSWER - digestion



Endocrine glands secrete into - CORRECT ANSWER - not ducts (ductless)



Endocrine glands secrete - CORRECT ANSWER - hormones



What type of gland does the pancreas have? - CORRECT ANSWER - both Endocrine and
Exocrine glands


Structural Classification of glands - CORRECT ANSWER - Unicellular and Multicellular



Unicellular glands are also called - CORRECT ANSWER - goblet cells



goblet cell - CORRECT ANSWER - unicellular exocrine gland that produces mucus



Where is mucus from goblet cells secreted? - CORRECT ANSWER - into ducts or onto
the surfaces of cells
