Joints) Study Guide Questions 2025
simple epithelial tissue - Correct Ans-- one cell layer thick
- function mostly in absorption and filtration
- found in areas that don't have a lot of friction
stratified epithelial tissue - Correct Ans-- more than one cell layer thick
- major function is in protection
- found in areas with lots of abrasion
pseudostratified epithelial tissue - Correct Ans-- looks like more than one cell layer thick
because of the nuclei but is only one cell layer thick
- greek pseudo means fake or false
- each cell has contact with the basal layer of the basement membrane
- sometimes apical surfaces are not equal
- found in areas with little movement
-ex. respiratory tract
squamous - Correct Ans-flat
cuboidal - Correct Ans-- same length and width
- involved in secretion
columnar - Correct Ans-- greater length then width
- found in high numbers in the digestive and respiratory tract
transitional - Correct Ans-- characterized by a dome shape at the apical surface
- transitional epithelium line hollow storage organs like the bladder
- as the storage containers fill up, the dome shape flattens, changing the capacity of
storage vessel
- this allows for filling of the storage container (bladder) without the stretching of the
container.
- eventually the container fills enough and is stretched
general functions of epithelial tissue - Correct Ans-- established boundaries
- protection
- absorption
- filtration
- excretion
- secretion
- sensory reception

establishes boundaries
- general function of epithelial tissue - Correct Ans-epithelial tissue acts as the limiting
boundary of the human organism
protection
- general function of epithelial tissue - Correct Ans-the epithelial tissue in the digestive
tract prevents us from digesting our own organs, and protect against the abrasive action
of food
absorption
- general function of epithelial tissue - Correct Ans-nutrients are absorbed through
epithelial tissue during digestion
filtration
- general function of epithelial tissue - Correct Ans-found mostly in the kidney
excretion
- general function of epithelial tissue - Correct Ans-we excrete metabolic wastes out of
the digestive system through epithelial tissue
secretion
- general function of epithelial tissue - Correct Ans-glandular epithelial tissue secretes
things
sensory reception
- general function of epithelial tissue - Correct Ans-- some cells in the epithelial tissue
are modified for sensory reception
- tactile/ touch sensory receptors in the skin allow for us to feel the ants crawling on our
body
apical surface - Correct Ans-exposed to the air/ free surface
basal surface - Correct Ans-- attached surface that is connected to something
- normally attaches epithelial tissue to connective tissue
the word surface is used to refer to... - Correct Ans-simple/ single cells
the word layers is used in reference to.... - Correct Ans-stratified cells
basement membrane - Correct Ans-- at the basal surface of epithelial tissue
- composed of the basal lamina and reticular lamina
Anatomy (BIOL 2220)
, Anatomy (BIOL 2220)
basal lamina - Correct Ans-- part of basement membrane
- noncellular sheet of glycoprotein
- basal layer secretes glycoprotein to help anchor the basal layer to the connective
tissue
reticular lamina - Correct Ans-- part of basement membrane
- collection of collagen fibers
- adds strength and integrity to the basement membrane
what two things work together to connect epithelial tissue to connective tissue - Correct
Ans-glycoproteins and collagen
basement membrane keeps _______ anchored - Correct Ans-- epithelial tissue
- if not, out skin would literally fall/ slough off
epithelial cells are avascular meaning/ because... - Correct Ans-- avascular means no
blood vessels
- every living cell needs to be able to exchange nutrients/ wastes with the circulatory
system
- the basement membrane keeps epithelial and connective tissues intact to allow for
that exchange to occur
covering and lining epithelial tissue - Correct Ans-- all free body surfaces (surfaces
exposed to the atmosphere) have epithelial tissue lining them
- mouth to anus is basically a tube
- things in the digestive tract are technically outside of our body; therefore the lining of
the digestive tract is covering and lining epithelial tissue
- the linings of the digestive, respiratory, and parts of the reproductive tract have
epithelial tissue
glandular epithelial tissue - Correct Ans-- glandular epithelial tissue is the secretory part
of the gland
- part that secretes things
- adrenal gland secrete epinephrine
gland - Correct Ans-- a cell or groups of cells of specialized epithelium that secretes
substances into ducts, onto surfaces of cells, or into the bloodstream
- requires energy to produce and secrete its secretory products
ducts are... - Correct Ans-tubules that directs to a specific place
can glands be unicellular or multicellular - Correct Ans-yeah
true or false
secretions are mostly, but not always water based - Correct Ans-true
Anatomy (BIOL 2220)
, Anatomy (BIOL 2220)
do cellular secretions use endo- or exocytosis - Correct Ans-- exocytosis
- an active transport process
exocrine glands - Correct Ans-- secrete into ducts
- most are associated with digestion
- exocrine secretions from the pancreas include enzymes to break down large nutrients
- these secretions travel through a duct that lead to the small intestine where they are
used to break down the nutrients
endocrine gland - Correct Ans-- ductless glands
- secrete hormones
- these hormones get into the bloodstream and are circulated throughout the body
do some organs have both exocrine and endocrine glands
- give an example - Correct Ans-pancreas
- part of the pancreas secretes digestive enzymes into ducts (exocrine)
- part of the pancreas secretes insulin and glucagon into the bloodstream (endocrine)
unicellular glands - Correct Ans-- also called GOBLET CELLS (unicellular exocrine
gland)
- produce and secrete mucus into ducts or onto the surfaces of cells
- goblet cells are a type of mucous gland because mucus contains mucin
- mucus act in the trapping of foreign substance as well as in lubrication
structures that produce mucus are called - Correct Ans-mucous glands
mucous glands secrete a protein called - Correct Ans-mucin
multicellular glands - Correct Ans-- cells within a multicellular gland
- there can be multiple tasks within a multicellular gland
- these tasks are based on the structure of the cells making up the gland (structure
dictates function)
- can be simple, branched, or multibranched
simple, branched, multibranched multicellular glands - Correct Ans-LOOK AT SLIDE 16
ON TISSUE POWERPOINT
merocrine glands - Correct Ans-- multicellular glands
- produce substances and store the substances within the cell
- cell eventually released substances into a duct without any damage to the cell
