- 18. A handle located between the eyepiece and the stage on a CLM
- 20. The microscope used to view larger bulkier items. This microscope has a maximum magnification of 125X
- 21. A medulla pattern that has consistent breaks
- 22. The objective lens that has the same magnification power as the eyepiece
- 24. The microscope that provides the greatest magnification power of all microscopes at 500,000X. This microscope requires a vacuum system and does not provide the real color of the specimen
- 26. The objective lens that has a magnification power of 40X
- 27. The innermost layer of hair that has unique patterns. This layer is the thickest layer in animal hair and is used to determine if it is animal or human hair by dividing the thickness of this layer by the thickness of the entire hair
