| Term | Definition |
|---|---|
| cytology | study of cells |
| histology | study of tissues |
| microscopic anatomy | structures that cannot be seen without magnification |
| gross anatomy | structures visible to the naked eye |
| surface anatomy | study of how deep or close to the surface |
| regional anatomy | study of a specific area |
| systemic anatomy | study of a body's organ system |
| order of organ systems | atoms-> molecules-> macromolecules-> organelles-> cells-> tissues-> organ-> organ systems |
| ribosomes | protein synthesis |

| osteoblasts | build up bone |
| osteoclasts | break down bone |
| osteoprogeniter | precursor |
| red bone marrow | red blood cell production |
| periosteum | lining outside the bone |
| indosteum | inner lining of the bone ; bulk of red blood cell production |
| flat bones | ribs, sternum, skull bones |
| sarco- | something to do with muscles |
| mys-, myo- | dealing with muscles |
| skeletal muscle | voluntary, controlled by the somatic nervous system |
