Q: Which of the following is the correct formula for calculating total magnification on a compound microscope?

$$\text{Total Magnification} = \text{Objective Lens Magnification} \times \text{Ocular Lens Magnification}$$

Q: If you are using a 10X ocular lens and a 40X objective lens, what is the total magnification?

$$\text{Total Magnification} = 10 \times 40 = 400$$

Q: A student observes a specimen under low power (10X objective, 10X ocular) and measures the field diameter as 2 mm. What would be the estimated field diameter under high power (40X objective, 10X ocular)?

$$\text{Field Diameter}_{\text{high}} = \frac{\text{Field Diameter}_{\text{low}} \times \text{Total Magnification}_{\text{low}}}{\text{Total Magnification}_{\text{high}}} = \frac{2 \times 100}{400} = 0.5\ \text{mm}$$

Accepted Answer

Cranial cavity

Question 6

A transverse section through the abdomen would result in which type of view?

Accepted Answer

A horizontal view dividing the body into superior and inferior parts.

Question 7

Which of the following is the correct formula for calculating total magnification on a compound microscope?

Accepted Answer

$$	ext{Total Magnification} = 	ext{Objective Lens Magnification} 	imes 	ext{Ocular Lens Magnification}$$

Question 8

If you are using a 10X ocular lens and a 40X objective lens, what is the total magnification?

Accepted Answer

$$	ext{Total Magnification} = 10 	imes 40 = 400$$

Question 9

Which of the following statements about working distance in microscopy is correct?

Accepted Answer

Working distance decreases as objective lens magnification increases.

Question 10

A student observes a specimen under low power (10X objective, 10X ocular) and measures the field diameter as 2 mm. What would be the estimated field diameter under high power (40X objective, 10X ocular)?

Accepted Answer

$$	ext{Field Diameter}_{	ext{high}} = \frac{	ext{Field Diameter}_{	ext{low}} 	imes 	ext{Total Magnification}_{	ext{low}}}{	ext{Total Magnification}_{	ext{high}}} = \frac{2 	imes 100}{400} = 0.5\ 	ext{mm}$$

Question 11

Which microscope part is responsible for adjusting the amount of light passing through the specimen?

Accepted Answer

Iris diaphragm lever

Question 12

When preparing a wet mount of the letter 'e', what is the correct sequence of steps?

Accepted Answer

Place the letter 'e' on the slide, cover with a cover slip, add a drop of water at the edge of the cover slip.

Question 13

Which directional term best describes the position of the lungs relative to the heart?

Accepted Answer

Lateral

Question 14

A patient complains of pain in the right lower quadrant of the abdomen. Which organ is most likely involved?

Accepted Answer

Appendix

Question 15

Which of the following best describes the term 'proximal'?

Accepted Answer

Closer to the origin of a body part or the point of attachment of a limb to the body trunk.

Question 16

Which of the following is a correct real-life application of the term 'distal'?

Accepted Answer

The fingers are distal to the elbow.

Question 17

Which of the following statements about the dorsal and ventral body cavities is correct?

Accepted Answer

Question 18

A patient is lying face down on an examination table. Which anatomical term best describes this position?

Accepted Answer

Prone

Question 19

Which of the following best describes the function of the coarse adjustment knob on a microscope?

Accepted Answer

It allows large movements to adjust the height of the stage to initially focus the specimen.

Question 20

If you observe a specimen under the 4X objective lens and the field diameter is 4 mm, what is the field diameter under the 10X objective lens?

Accepted Answer

$$	ext{Field Diameter}_{10X} = \frac{4 	imes 4}{10} = 1.6\ 	ext{mm}$$
