|---|
| diaphragm (microscope) | a circular disc with different sized of openings in to that allow different amounts of light to pass through to the specimen |
| organ | a collection of tissues joined in structural unit to serve a common function |
| organ system | collection of organs that work together to perform specific tasks |
| diaphragm (human body) | a wall of muscle that separate the two cavities of the trunk |
| tissue | an ensemble of similar cells and from the same origin, that together carry out a specific function |
| organism | any unicellular or multicellular contiguous living system (such as animal, fungus, micro-organism, or plant). |
| cranium | cavity of the body that holds the brain |
| pelvic cavity | contains all the organs of the excretory and reproductive system |
| trunk | everything except the head/neck and limbs |
| coarse focus | larger nob on the microscope, moves the stage in large amounts, allows a specimen to get into initial focus |
| objective lens | one of three different lenses that are nearest to the specimen |
| abdominal cavity | organs located below the diaphragm that contain mainly the digestive system organs |
| integument | refers most commonly to the natural covering of an organism or an organ, such as its skin, husk, shell, or rind |
| metabolism | set of chemical reactions that happen in the cells of living organisms to sustain life |
| fine focus | smaller nob on the microscope that moves the stage in very small amounts; allows the viewer to bring the speculum into sharp focus |
| endocrine | system of the body that deals with the different glands |
| cell | the basic "unit" of life |
| ocular lens | the lens that you look through on a microscope |
| homeostasis | the property of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties such as temperature or pH |
| thoracic | upper section of the trunk, above the diaphragm, contains: lungs, heart and esophagus |
| stage & clips | where a slide is placed and secured, there is an opening that allows light to pass through the specimen |
