| 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 |
