Which component of the compound light microscope connects the eyepiece to the objective lenses?

The component of the compound light microscope that connects the eyepiece to the objective lenses is the arm. The arm provides structural support and houses the components that allow the light to travel from the objective lenses to the eyepiece, where the image is magnified for the viewer. This part of the microscope is integral to the overall functionality as it also aids in carrying and positioning the microscope.

The head, which is sometimes confused with the arm, is actually the part that holds the objective lenses and eyepiece but does not connect them directly. The base serves as the foundation of the microscope, providing stability and support, while the stage is the platform where the specimen slide is placed for observation. Each of these components plays a role in the operation of the microscope, but the arm is specifically the element that facilitates the connection between the eyepiece and objectives.
