Actual Answers 2026-2027 Updated.
histology - Answer study of normal structure of tissues
tissue - Answer groups of cells, similar in structure, that cooperate to perform a function
ground substance, fibrous protein - Answer Cell are embedded in an ECM of _______ & _____.
epithelial - Answer type of tissue with sheets of tightly packed cells, little visible ECM
covering & linings, glands - Answer Epithelial tissue is found in what 2 primary locations?
connective - Answer type of tissue with loosely scattered cells, ECM is most prominent feature
connective - Answer type of tissue that functions in binding, supporting, protecting &
connecting parts of body
muscular - Answer type of tissue with long, cylindrical or spindle shaped cells, little visible
ECM
muscular - Answer type of tissue that functions in contracting to generate force
nervous - Answer type of tissue where cells exhibit numerous processes, mostly fluid ECM
nervous - Answer type of tissue involved in processing & transmitting info.
cell - Answer responsible for secreting and maintaining ECM
GAGs, proteoglycans, glycoproteins - Answer What are the 3 major macromolecules in ground
substance of ECM?
collagen, elastic, fibrocartilage - Answer What are the 3 main types of fibrous proteins of
ECM?
GAGs - Answer charged macromolecule that attracts water molecules in ECM
,proteoglycan - Answer "bottle brush" like structures that slow down pathogens & connect
ECM to cell membranes
glycoprotein - Answer macromolecule that binds plasma membranes to extracellular collagen
& proteoglycans
collagen - Answer type of fibrous protein used for tough, stretching resistance
reticular - Answer type of fibrous protein that forms spongelike frameworks for spleen &
lymph nodes
elastic - Answer type of fibrous protein that has coiled protein w/ ability to recoil
squamous - Answer type of epithelial cell that is flattened like fried eggs; found in epidermis
cuboidal - Answer type of epithelial cell that is squared; found in glands
columnar - Answer type of epithelial cell that is rectangular; found in small intestine
polygonal - Answer type of epithelial cell that looks like tops of columnar cells
stellate - Answer type of epithelial cell that is star shaped; nervous tissues
spheroidal - Answer type of epithelial cell that WBCs are
discoid - Answer type of epitheial cell that RBCs are
fusiform - Answer type of epithelial cell that is longer than squamous, spindle shaped & not as
tightly packed
fibrous - Answer type of epithelial cell that is much longer than they are wide
cell junction; blood - Answer physical connection b/w tissue cells; all cells (except which
ones?) are anchored to each other or their matrix by such structures
, tight junction - Answer integral membrane proteins of adjacent cells lock together to form
impermeable seal
desmosome - Answer integral membrane proteins of adjacent cells interweave b/w cells &
connect to intermediate filaments within cells; resist mechanical stress
gap junction - Answer interlinked protein pores that allow substances to pass b/w cells
apical - Answer portion of epithelial cell associated w/ external environment or organ cavity
basal - Answer portion of epithelial cell associated w/ non cellular filter b/w tissue types
T - Answer (T/F) Epithelial tissues are avascular.
F - Answer (T/F) Epithelial tissues are not nervated.
T - Answer (T/F) Epithelial tissues are capable of regeneration.
F - Answer (T/F) Epithelial tissues are rarely supported by CT.
excretion - Answer removal of wastes/toxins
secretion - Answer removal of something useful
goblet cell - Answer wineglass shaped cell amongst columnar cell tissues that secrete mucous
simple squamous - Answer type of epithelial tissue that permits rapid diffusion or transport
across cells, secretes lubricating serous fluid; found in lung alveoli, kidney glomeruli,
endothelium, serosa
simple cuboidal - Answer type of epithelial tissue that functions in absorption & secretion,
ciliated in lungs; found in liver, thyroid, mammary, salivary, kidney, tubules, & bronchioles
simple columnar - Answer type of epithelial tissue that forms brush border of microvilli, often
has goblet cells & functions in absorption & secretion; found in GI tract lining, uterus, kidneys,
uterine tubes
