| Term | Definition |
|---|---|
| embryo forms | inner cell mass |
| endoderm | inner layer, becomes epithelium of gut, respiratory, and lower urinary tract |
| ectoderm | outer layer, forms hair and hooves |
| mesoderm | formed from cells between hypoblast (endoderm)and epiblast(ectoderm) , becomes the coelom |
| somatic layer | gives rise to bones, ligaments, blood vessels, andconnective tissue |
| epiblast | develops into the ectoderm |
| hypoblast | develops into the endoderm |
| splanchnic layer | forms the heart, gut, muscles, and blood vessels |
| notochord | develops from the mesoderm, eventually becomes the spine |
| endothelium | forms inner lining of the heart, blood vessels, and lymph vessels |
| cuboidal cells | equal height and width, found on outer coveringof the ovary and glandular tissue like thyroid, kidney tubules |
| transitional cells | expand when bladder is full and contract when bladder is empty |
| pseudostratified cell | appears to have many layers but onl has one |
| apocrine gland | accumulate secretory products then pinch off or die |
| mucous membrane | line the hollow organs and cavities like the digestive, respiratory, urinary and reproductive systems |
| dense regular connective tissue | arranged in parallel bundles and forms tendons |
| smooth muscle tissue | involuntary, non-striated and makes up walls of blood vessels or tubular organs |
| hemolysis, or the bursting of red blood cells occurs when a ____ solution is infused | hypotonic |
| molecules that require a carrier protein to cross the lipid bilayer of the cell membrane but does not require energy is | diffusion |
| infusion of a solution greater than 5% glucose would result in water being drawn out of red blood cells. this is called | crenation |
| the majority of total body water is found in | intracellular fluid |
| fluid that bathes tissue cells is found in the extracellular and intercellular space | interstitial fluid |
