Lab 02: Introduction to Microscopy and Histology Flashcards

Vocabulary flashcards covering microscope parts, functions, microscopy concepts, and tissue and cell types from Lab 02.

Stage

The platform on which the slide rests for viewing.

Iris diaphragm lever

The microscope component used to regulate or adjust the amount of light passing through the specimen.

Mechanical stage

The component that controls the movement of the slide on the stage.

Condenser

The microscope structure that delivers a concentrated beam of light to the specimen.

Fine adjustment knob

The control knob used for precise focusing to bring an object in rough focus into sharp focus.

Nosepiece

The rotating part of the microscope that carries the objective lenses so different objective lenses can be brought into position over the specimen.

Ocular lens

The eyepiece lens of the microscope, which has a magnification of 10x.

Scanning objective lens

An objective lens that has a magnification of 4x.

Coarse adjustment knob

The control knob used to bring a specimen into rough focus, typically used with lower power objectives like the 4x objective.

Depth of field

The thickness of the plane that is clearly in focus; it is greater at lower magnifications and decreases as magnification increases.

Contrast

One of the three factors affecting image quality, which is altered by the light source and iris diaphragm lever.

Red blood cells

Cells whose structure enables them to transport oxygen and carbon dioxide.

White blood cells

Cells whose structure enables them to be involved in immunity.

Proper Microscope Transport Technique

Depicted in Picture A, where one hand firmly holds the arm and the other hand supports the base while keeping the microscope upright.
