Answer:
1. Base - acts as microscopes support.
2. Mirror- used to reflect light from an external light source up through the bottom of the stage.
3. Diaphragm - known as the iris. Its found under the stage of the microscope and its primary role is to control the amount of light that reaches the specimen.
4. Stage - the section on which the specimen is placed for viewing.
5. Stage Clip - hold the specimen slides in place.
6. Low-power Objectives - examining large specimens or surveying many smaller specimens.
7. High-power Objectives -ideal for observing very fine detail, such as nerve cells in the retina or the striations in skeletal muscle.
8. Revolving Nosepiece - holds two or more objective lenses and can be rotated to easily change power.
9. Arm - Supports the tube and connects it to the base.
10. Fine Adjustment Knob - slow but precise control used to fine focus the image when viewing at the higher magnifications.
11. Body Tube - separates the objective and the eyepiece and assures continuous alignment of the optics.
12. Coarse Adjustment Knob - allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.
13. Eyepiece - also known as the ocular. this is the part used to look through the microscope.
