Light adjustment knob: It allows you to adjust the light where you can see the specimen, and set it so that you can comfortably use the microscope without straining your eyes. If the knob was broken and the light was too bright, you should not want to use it. Many people don't worry with it and put their light at maximum causing them eyestrain or headaches after some time.
And the lenses are also important.
The parts of a microscope can be classified into two main categories: optical components, which include the eyepiece, objective lenses, and stage, and mechanical components, which include the frame, focusing system, and illumination system. The optical components are responsible for magnifying and focusing the specimen, while the mechanical components support and adjust the position of these optical parts.

Some common microscope rules include always starting with the lowest magnification, focusing carefully using coarse and fine adjustment knobs, keeping the lenses clean, handling slides gently, and using the microscope in a well-lit area. Additionally, it's important to never force any parts, such as the stage or focusing mechanisms, and to always carry the microscope with two hands.
There're two knobs at the side of a light microscope (this is just my experience, it may be different if you're using different brands of microscope or even an electron type microscope). For first focus, adjust the larger knob (also known as rough adjustment) followed by the final focus (to sharpen the image), by adjusting the smaller knob (known as fine adjustment).
The two lenses in a compound microscope used in most classrooms today are the objective lens, located near the specimen, and the eyepiece lens, located at the top of the microscope where the viewer looks through. The objective lens magnifies the specimen, and the eyepiece lens further magnifies the image for the viewer.
When carrying a microscope, it is important to support both the base and the arm of the microscope to ensure stability and prevent damage to the instrument. Holding both parts securely will help maintain the balance of the microscope and prevent any potential accidents.

base and the arm
your hands should be on the arm of the microscope and under the base
The brain and the nerves!
there are two parts to answer your question. firstly, the arm of the microscope, and then lift up the microscope and place your hand under the microscope and grab the base. in short there is the arm and the base.

A microscope typically has two main parts: the optical system, which includes the lenses and eyepiece, and the mechanical system, which includes the frame and stage where the slide is placed. Some microscopes may also have additional parts like illuminators or digital imaging components.

A microscope is typically carried by holding the arm with one hand and supporting the base with the other hand. This helps ensure stability and prevents the microscope from tilting or falling.
