Anatomy (BIOL 2220) Exam 2 – Cummings
UPDATED Exam Questions and
CORRECT Answers
Tissues - CORRECT ANSWER - Collection of cells that work together to perform a
particular function
Histology - CORRECT ANSWER - Study of tissues
Epithelial tissue functions - CORRECT ANSWER - establishes boundaries
protection
absorption
filtration
excretion
secretion
sensory reception
Epithelial tissue types - CORRECT ANSWER - covering and lining (body inner donut)
glandular (covers glands)
Epithelial tissue apical surface - CORRECT ANSWER - upper free surface
Epithelial tissue basal surface - CORRECT ANSWER - deepest layer, below apical layer
epithelial tissue basement membrane - CORRECT ANSWER - basal lamina (right below
basal layer)
reticular lamina (network of proteins-mostly collagen- that become barrier, deep to basal lamina)
,Avascular - CORRECT ANSWER - no blood vessels, blood has to diffuse through
covering and lining epithelium types - CORRECT ANSWER - simple, stratified,
pseudostratified, squamous, cuboidal, columnar, transitional
simple epithelium - CORRECT ANSWER - one layer of cells, lots of absorption and
filtration
stratified epithelium - CORRECT ANSWER - more than one cell for material to go
through
pesudeostratified epithelium - CORRECT ANSWER - one cell layer but looks like more
than one, found in areas with little movement
squamous epithelium - CORRECT ANSWER - flat cells
cuboidal epithelium - CORRECT ANSWER - cells have same width as height
columnar cells - CORRECT ANSWER - cells are taller than they are wide
transitional - CORRECT ANSWER - lines hollow cavities like bladder, go from dome
cells to flat cells, allows organs to stretch
glands - CORRECT ANSWER - secret substances into ducts, blood, or onto surfaces
types of glands - CORRECT ANSWER - exocrine, endocrine, unicellular, multicellular,
merocrine, holocrine
exocrine glands - CORRECT ANSWER - secret into channel, then into ducts
, endocrine glands - CORRECT ANSWER - secretion into bloodstream (ex: hormones)
unicellular glands - CORRECT ANSWER - goblet cells produce mucus
multicellular glands - CORRECT ANSWER - composed of multiple cells
merocrine glands - CORRECT ANSWER - no destruction of cells during exocytosis
holocrine glands - CORRECT ANSWER - cell accumulates excretory material and then
carries it out of tissue and is destroyed to release the material
mesenchyme embryonic tissue - CORRECT ANSWER - connective tissue is derived from
connective tissue types - CORRECT ANSWER - connective tissue proper, cartilage, bone,
blood
connective tissue structural elements - CORRECT ANSWER - ground substance, fibers,
cells
muscle tissue - CORRECT ANSWER - cells modified for contraction, provide movement
and/or heat
muscle tissue contains - CORRECT ANSWER - sarcolema (plasma membrane)
sarcoplasm (cytoplasm)
muscle tissue types - CORRECT ANSWER - skeletal, cardiac, smooth
