Anatomy (BIOL 2220) Exam 2 – Cummings
Questions And Answers
Epithelial tissue basal surface deepest layer, below apical layer
epithelial tissue basement membrane basal lamina (right below basal layer)
reticular lamina (network of proteins-mostly collagen- that become barrier, deep to basal lamina)
Avascular no blood vessels, blood has to diffuse through
covering and lining epithelium types simple, stratified, pseudostratified, squamous,
cuboidal, columnar, transitional
simple epithelium one layer of cells, lots of absorption and filtration
stratified epithelium more than one cell for material to go through
pesudeostratified epithelium one cell layer but looks like more than one, found in areas
with little movement
, Anatomy (BIOL 2220) Exam 2 – Cummings
Questions And Answers
squamous epithelium flat cells
cuboidal epithelium cells have same width as height
columnar cells cells are taller than they are wide
transitional lines hollow cavities like bladder, go from dome cells to flat cells, allows
organs to stretch
glands secret substances into ducts, blood, or onto surfaces
types of glands exocrine, endocrine, unicellular, multicellular, merocrine, holocrine
exocrine glands secret into channel, then into ducts
endocrine glands secretion into bloodstream (ex: hormones)
, Anatomy (BIOL 2220) Exam 2 – Cummings
Questions And Answers
unicellular glands goblet cells produce mucus
multicellular glands composed of multiple cells
merocrine glands no destruction of cells during exocytosis
holocrine glands cell accumulates excretory material and then carries it out of tissue and is
destroyed to release the material
mesenchyme embryonic tissue connective tissue is derived from
connective tissue types connective tissue proper, cartilage, bone, blood
connective tissue structural elements ground substance, fibers, cells
muscle tissue cells modified for contraction, provide movement and/or heat
, Anatomy (BIOL 2220) Exam 2 – Cummings
Questions And Answers
muscle tissue contains sarcolema (plasma membrane)
sarcoplasm (cytoplasm)
muscle tissue types skeletal, cardiac, smooth
skeletal muscle tissue voluntary, striated, multinucleated
cardiac muscle tissue involuntary, striated, uninucleated
smooth muscle tissue involuntary, non-striated, uninucleated
nervous tissue contains neurons
neuroglia
neurons detect stimuli, send messages
