______ Supports the body tube and the stage of the microscope
______ Platform where the slide is placed for viewing
______ Holds the slide firmly in place on the stage
______ Hole in the stage that allows light to pass from the lamp or mirror, through the specimen, and into the body tube
______ Lowermost part of the microscope; provides firm and steady support
______ Holds the eyepiece lens and the objective lens the correct distance apart for magnification
______ Provides the light needed to view the specimen
______ Disk located directly below the stage of the microscope; regulates the amount of light passing through the stage opening
______ Larger knob used to elevate or lower the body tube or stage a large distance with each turn
______ Smaller knob used to elevate or lower the body tube or stage a small distance with each turn; used to make fine adjustments
when focusing on a specimen
______ Located at the upper end of the body tube; focuses light on the retina in the eye; usually has a magnification of 10X; the part
you look through
______ Magnifies the specimen; includes the scanning lens (4X), lower power lens (10X), and the high power lens (40X)
______ Rotates to allow changing objective lens
