Question 1

A one piece of equipment that is used by both the
pathologist and the histotechnologist.

Answer 1

MICROSCOPE

Question 2

A microscope must accomplish three things:

Answer 2

A. must magnify the objects
B. resolve the details of the object.
C. make these details visible.

Question 3

The most common and the first to be invented microscope.

Answer 3

COMPOUND MICROSCOPE

Question 4

Only use one eyepiece when viewing the specimen.

Answer 4

MONOCULAR HEADS

Question 5

Have two eyepieces and are more convenient and comfortable to use. It is the most common choice.

Answer 5

BINOCULAR HEADS

Question 6

Have a third eyepiece tube that can be used by another person simultaneously or by an LCD camera.

Answer 6

TRINOCULAR HEADS

Question 7

Provides support for the microscope.

Answer 7

BASE

Question 8

Supports and holds the magnifying and adjustment system.

Answer 8

ARM

Question 9

Is the flat platform where the slide is placed for examination.

Answer 9

STAGE

Question 10

Is located directly under the stage and holds the condenser
and diaphragm

Answer 10

SUBSTAGE

Question 11

Permits movement of the stage while holding the slide in the phase of focus.

Answer 11

MECHANICAL STAGE

Question 12

Is located at the end of the body tube for holding the objectives

Answer 12

NOSEPIECE

Question 13

Consist of a system of lenses located at the end of the body tube that is held in place by the nosepiece and is closer to the slide under examination

Answer 13

OBJECTIVES

Question 14

Is the distance between outer lens of objective and the cover glass of the slide under examination.

Answer 14

FOCAL LENGTH

Question 15

works on the same principle as an optical microscope but uses electrons instead of light and electromagnets instead of glass lenses.

Answer 15

TRANSMISSION ELECTRON MICROSCOPE

Question 16

a microscope that uses a beam of accelerated electrons as a source of illumination.

Answer 16

ELECTRON MICROSCOPE

Question 17

used in compound microscopes, where light is either passed through, or reflected off, a specimen.

Answer 17

BRIGHT FIELD MICROSCOPY

Question 18

used to observe unstained and transparent samples causing them to be clearly visible and appear brightly lit against a dark, almost purely black background.

Answer 18

DARK FIELD MICROSCOPY

Question 19

a type of light microscopy that enhances contrasts of transparent and colorless objects by influencing the optical path of light.

Answer 19

PHASE CONTRAST MICROSCOPY

Question 20

a contrast-enhancing technique that improves the quality of the image obtained with birefringent materials when compared to other techniques

Answer 20

PORALIZED LIGHT MICROSCOPY

Question 21

This microscopy requires intense, near-mono-chromatic, illumination which some widespread light sources, like halogen lamps cannot provide.

Answer 21

FLUORESCENCE MICROSCOPY
