Q

Ocular lens

A

“Eye piece”; part of the microscope that is looked through

2
Q

Objective lenses

A

Attached to a nosepiece or turret at the base of the microscope’s body tube

3
Q

How do you calculate total magnification?

A

Ocular lens x objective lens

4
Q

Body tube

A

Transfers light from the objective lenses through another series of lenses to the ocular lens

5
Q

Arm

A

Connects the body tube to the rest of the instrument

6
Q

Stage

A

Platform on which the microscope slide rests

7
Q

Diaphragm

A

One of the controls that varies the amount of light reaching a specimen

8
Q

Condenser

A

Focuses light onto the specimen

9
Q

Light source

A

Illuminates the specimen on stage

10
Q

Coarse adjustment

A

Bring a specimen initially into focus; usually large knobs located on the sides of the arm, just below the microscope’s stage

11
Q

Fine adjustment

A

Used for small adjustments in focus

12
Q

How to prepare a wet mound

A
  1. Obtain a clean microscope slide and a cover slip.
  2. Use the broad end of the toothpick to scrape the inside of your cheek.
  3. Place the cells on the center of the slide.
  4. Place a water drop on the cells and stir the cells with the toothpick.
  5. Allow the cells to dry for a minute or two.
  6. Place the cover slip next to the water drop at about a 60 degree angle.
  7. Slowly lower the cover slip until it rests flat on the slide.
  8. Place a drop or two of METHYLENE-BLUE stain on the slide beside the cover slip.
  9. Use a piece of paper towel to draw the stain under the cov slip by placing it opposite the stain.

A

Towards the back of the body or the vertebral column; ex: the vertebral column is dorsal to the lungs

14
Q

Ventral

A

Towards the front of the body; ex: the sternum is central to the lungs

15
Q

Anterior

A

2 legged: toward the front of the body or the ventral surface; 4 legged: towards the head; ex: the sternum is anterior to the vertebrae

16
Q

Posterior

A

2 legged: towards the body or dorsal surface of the body; 4 legged: toward the tail; ex: the lungs are posterior to the sternum

17
Q

Proximal

A

Closer to the point of reference; ex: the femoral head is on the proximal end of the leg

18
Q

Distal

A

Further from the point of reference; ex: the foot is on the distal end of the leg

19
Q

Superior

A

Above the point of reference; ex: the eyes are superior to the nose

20
Q

Inferior

A

Below the point of reference; ex: the mouth is inferior to the eyes

21
Q

Superficial

A

Towards the surface of the body; ex: the skin is superficial

22
Q

Deep

A

Away from the body’s surface; ex: the heart is deep

23
Q

Medial

A

Towards the midline or the median plane of the body; ex: the sternum is medial

24
Q

Lateral

A

Away from the midline or the median plane of the body; ex: the ears are lateral

25
Q

Peripheral

A

Away from the midline or center of the body; ex: the cheeks are peripheral to the teeth
