Card Set Information
when several cells come together to do a specific job or function
4 major tissues
flat, scale like, flat nulceus
square or round, roundish nucleus
tall, slender, oval nucleus
single flat sheet
many sheets, stacked on each other
looks like many layers but is really only one
Simple squamous epithelium
lines air sacks in lungs for good gas exchange and also in capilaries
simple cubodial epithelium
specialized for secretion and lining ducts
found in glands
simple columnar epithelium
specialized for absorption n secretion
sometimes posess cilia. digestive system
stratified squamous epithelium
many layers of stacked flat cells
found in skin and espophagus
pseudostratified ciliated columnar epithelium
lines the airways.
secretes mucous onto the tissue surface
stretches, found in the urinary bladder and ureters
blood and bone
have cells, contain network of reienforcing fibers. In matrix
3 types of fiber in connective tissue
collagen, elastic, reticular
primary quality is strength
stretch then snap back into place
net like, catch and hold cells in place
what cells and fibers live in
gel like protien hardened by minerals and is therefore ridid
reasonably flexible or malleable
protiens are disolved in water.
loose areolar connective tissue
loosly connect organs to each other.
skeletal, cardiac, smooth
long and thin.
the cytoskeleton (actin and myosin filaments), bundles of striated, voluntary
: to move the skeleton
cells are branched, one nucleus, striated
involuntary special connections called intercalated discs.
only in the heart
slender and pointed (spindle-shaped)
involuntary found in organs.
major cell type is the neuron
responsible for generating and interpreting messages.
support cell for neurons
