Question

Here is my labeling of the anatomy of a microscope. I'm missing one thing here. Can you tell me what it is?

Answer 1

Also, it isn't on this labeling sheet, but there are these two knobs next to the diaphragm, that are not the coarse and fine adjustments, what are they?

Answer 2

I don't know what your missing piece is - I honestly cannot remember - but the two 'knobs' as you put it are clips to help hold your samples in place as you look at them.

Answer 3

There's the "head" of the microscope.
And it looks you would write "head" at the very top of the right column of words.
