Question 1

Arm

Answer 1

Connects the base and barrel; held in transport

Question 2

Body tube

Answer 2

Holds revolving nosepiece; houses lenses and mirrors

Question 3

Condenser

Answer 3

Focus light on specimen

Question 4

Course focus adjustment

Answer 4

Moves stage a lot; only used in low power; raises and lowers stage

Question 5

Diaphragm

Answer 5

Regulates the light (located on bottom if stage)

Question 6

Fine focus adjustment

Answer 6

Small movements of stage- up and down

Question 7

High power objective (40x)

Answer 7

Magnifies

Question 8

Iris diaphragm lever

Answer 8

Beneath condenser- further adjusts the amount of light a specimen receives

Question 9

Light source

Answer 9

Provides light for viewing specimen

Question 10

Low power objective (10x)

Answer 10

Magnifies- medium power

Question 11

Mechanical stage

Answer 11

Holds slides

Question 12

Mechanical stage adjuster

Answer 12

Top- forward and back

Bottom- stage clip side to side

Question 13

Nose piece (rotating turret, revolving nosepiece)

Answer 13

Holds objectives; rotates to change objective

Question 14

Ocular lens

Answer 14

Eye piece- where you look; usually 10x magnification

Question 15

Oil immersion (100x)

Answer 15

Magnifies; not used in a&p 1

Question 16

Scanning objective (4x)

Answer 16

Low power; red band; end position

Question 17

Slide retainer clip (stage clip)

Answer 17

Holds slides in place

Question 18

Depth of field

Answer 18

Thickness if the plane of focus; how much the specimen can move and still be in focus

Question 19

Magnification/ magnifying power

Answer 19

Amount the specimen has been enlarged in appearance, not actual size

Question 20

Parfocal

Answer 20

Stay in focus when magnification is changed; objectives can be changed with little to no refocusing

Question 21

Resolution

Answer 21

Ability to distinguish 2 distinct points; higher resolution- closer the points can be while still able to distinguish them

Question 22

Total magnification

Answer 22

Ocular lens and objective (10x times 4x is 40x magnification)

Question 23

Working distance

Answer 23

Decreases as magnification and numerical aperture both increase; distance between the front edge of the objective lens and the specimen surface when the specimen is focused

Question 24

Field of view

Answer 24

The amount of things you are looking for (as magnification goes up, field of view goes down)
