Low power(10x)
High Dry(45x or 40x)
Oil immersion(100x)
Eyepeice+objective lens=total magnification |

|
Definition
Camel hair brush
Lens cleaner/Lens paper

|
|
Term
|
Definition
Most common type of microscopy
light source emits light in the visible wavelength range
Object appear dark against a light background
Elements with a low refractive index can be easily
overlooked if light is too intense |
|
|
Term

Definition
Specialized parts added to the sub-stage condenser
Out-of-phase

|
Term
|
Definition
Light waves that travel in pairs in asynchronized patterns
(Makes objects more visible) |
|
|
Term
|
Definition
Light waves that travel in pairs in synchronized pattern
(Objects that cannot be contrasted from their surroundings are not easily recognized) |
|
|
Term
| Phase contract microscopes are useful in identifying what? |
|
Definition
| Hyaline casts or mmixed cellular casts, mucous threads, and trichomonas |
|
|
Term
|
Definition
Used to see and differentiate low refractive elements like crystals and lipids
Unidirectional light beam is directed through an object
As light passes through the object, the path of the light beam is rotated
Rotation of light producess characteristic colors from crystals and lipids
These colors are not seen in the brightfield microscope
these elements are birefringent |
|
|
Term
| Polarized microscopy is used to confirm what? |
|
Definition
| The identification of fat droplets, oval fat bodies, and fatty casts that produces maltese cross pattern |
|
|
Term
| Principle of microscopic examination |
|
Definition
Examination of urine sediment in urine
Correlate microscopic results with the physical and chemical analysis |
|
|
Term
| purpose of micro examination |
|
Definition
| Detect and ecaluate renal urinary tract disorders or diseases |
|
|
Term
| Purpose of urine fat stain |
|
Definition
Enhanced the identification of urinary fat sediments through the use of sediment stain
|
|
|
Term

Definition
|
|
Term
(Polarizing microscopy can be used to confirm the presence of fat droplets and lipid-coontaining cells)
Triglycerides and neutral fat stains
Cholesteral |
|
Definition
Orange-red
No stain but produces polarization |
|
|
Term
| Common structures found in urine sediment |
|
Definition
CELLS - Erythrocytes, leukocytes, epithelial cells, renal tubular epithelial cells, Transitional epithelial cells, Squamous Epithelial cells
Crystals - Precipitated urine salts
Casts - Formes in tubules
Misc - Parasites, Bacteria, Yeast, Mucous |
