Question | Answer |
---|---|
histology | study of tissues |
mesenchyme | connective tissue proper,cartilage,bone and blood dervie from this embryonic tissue |
smooth muscle tissue | found in walls of hollow organs,two layers,uninucleate and spindle shaped |
cardiac muscle tissue | only in the heart, involuntary movement,branching uninucleate cells that fit togther: intercalated discs |
skeletal muscle tissue | meat of flesh attached to the skeleton,voluntary control,long cylinclrical and several nuclei per cell |
matrix componet: fibers | provides support, includes collagen fibers,elastic fibers and reticular fibers |
matrix componet: ground substance | composed of interstitial fluid,cell adhesion,proteins and protenoglycans |
hematopoietic | blood forming tissue replenishes the body's supply of red blood cells |
adipose | fat tissue provides insulation for the body tissues; source of stored food |
areolar connective tissue | soft packaging material that cushions and protects body organs |
dense connective tissue | ligaments and tendons |
osseous tissue | bone |
connective tissue | primarly for protection,support and to bind together other tissues fo the body |
exocrine glands | retain ducts, secretions empty through ducts to epithlial surface; both external and internal glands |
endocrine gland | ductless glands, secretions are all hormons extrued directly into the blood or lymphocic vessels that weave through glands |
transitional shape | shape that can change; flat when full, round when emtpy |
columnar shape | column shaped |
cuboidal shape | cubed shaped |
squamous shape | flat and wide shaped |
stratified | many layers; protects |
simple | one layer; absorbs and for secretion |
what are the four types of tissue | epithelial, connective, muscular, nervous |
connective tissue characteristics | contains a matrix; contains rich supply of blood vessels |
matrix | non-cellular, non-living material between cells of connective tissue |
characteristics of epithelical tissues | regeneration,avascularity,supported by connective tissues,celluarity,polarity |
