To solve this labeling task, we need to match each blank box on the diagram with the correct part of the microscope from the word bank. We will go through the labels systematically, starting from the top and moving down, identifying what each pointer is indicating based on standard microscope anatomy.

Left Side Labels (Top to Bottom):
1. Topmost Box: Points to the eyepieces where you look through. These are called the ocular lens.
2. Second Box: Points to the main structural frame that connects the head to the base. This is the body tube or simply the body in this context.
3. Third Box: Points to the curved handle used to carry the microscope. This is the arm.
4. Fourth Box: Points to the large knob used for rough focusing. This is the coarse adjustment knob.
5. Fifth Box: Points to the flat platform where slides are placed. This is the stage.
6. Sixth Box: Points to the lens system below the stage that focuses light onto the specimen. This is the condenser.
7. Seventh Box: Points to the very bottom support of the microscope. This is the base.

Right Side Labels (Top to Bottom):
1. Topmost Box: Points to the rotating turret that holds the objective lenses. This is the revolving nosepiece.
2. Second Box: Points to the small clips on the stage that hold the slide in place. This is the stage clip.
3. Third Box: Points to the smaller knob inside or next to the coarse knob, used for precise focusing. This is the fine adjustment knob.
4. Fourth Box: Points to the mechanism under the stage that controls the amount of light passing through. This is the iris diaphragm.
5. Fifth Box: Points to the lamps at the bottom providing illumination. This is the light source.

Bottom Center Label:
* There is a final box at the very bottom pointing to the objective lens (specifically one of the lenses attached to the nosepiece). Wait, looking closer at the lines:
* The line from the "Objective lens" box isn't explicitly drawn as a separate line in the list above, but looking at the diagram, there is a label pointing directly to one of the black cylinders hanging from the nosepiece. That must be the objective lens.

Let's re-verify the mapping based on the specific lines in the image provided.

Left Column Mapping:
1. Top box -> Points to the eyepieces -> ocular lens
2. Second box -> Points to the upper housing -> body
3. Third box -> Points to the arm structure -> arm
4. Fourth box -> Points to the large focus knob -> coarse adjustment knob
5. Fifth box -> Points to the stage surface -> stage
6. Sixth box -> Points to the condenser area -> condenser
7. Seventh box -> Points to the base -> base

Right Column Mapping:
1. Top box -> Points to the revolving nosepiece -> revolving nosepiece
2. Second box -> Points to the stage clips -> stage clip
3. Third box -> Points to the fine focus knob -> fine adjustment knob
4. Fourth box -> Points to the diaphragm -> iris diaphragm
5. Fifth box -> Points to the light -> light source

Center/Bottom Mapping:
There is a box at the very bottom center pointing up towards the objective lenses.
1. Bottom Center Box -> Points to the objective lenses -> objective lens

Final Answer:
Left Column (Top to Bottom):
1. ocular lens
2. body
3. arm
4. coarse adjustment knob
5. stage
6. condenser
7. base

Right Column (Top to Bottom):
1. revolving nosepiece
2. stage clip
3. fine adjustment knob
4. iris diaphragm
5. light source

Bottom Center:
1. objective lens
