inner layer; covers organ; stomach, spleen liver, intestine)

Answer 7

visceral layer

Question 8

outer layer that lines body cavity (Located in abdomen, lining abdominal and pelvic cavity)

Answer 8

parietal layer

Question 9

relationship between total magnification and depth of focus?

Answer 9

Each time you switch to a higher power, the depth of focus is reduced.
- magnification increase (objective is close to slide), field of view decrease

Question 10

distinguish fine detail of object

Answer 10

resolution

Question 11

change magnification without refocusing

Answer 11

parfocal

Question 12

distance from objective lens to slide

Answer 12

working distance

Question 13

relationship between the ocular lens magnification, the objective
lens magnification and the total magnification?

Answer 13

ocular lens magnifies object an additional 10x more than the objective lens. Total magnification is the product of both lenses

Question 16

what is in left lower quadrant

Answer 16

left ureter, intestines, reproductive organs (fallopian tube, ovary)

Question 17

what is in left upper quadrant

Answer 17

Liver, stomach, pancreas, left kidney, spleen, and the left adrenal gland.

Question 18

what supports the objective lenses

Answer 18

revolving nose piece

Question 19

what are the 3 objective lenses

Answer 19

4x lens = low power objective lens
10x lens = medium power objective lens
40x= highest power
