GENERAL HISTOLOGY

Detailed explanation-1: -Mechanical stage – flat surface on which the slide is held in place by the specimen holder. The stage can be moved up or down by the Coarse adjustment knob or Fine adjustment knob which are on the microscope arm to focus on different levels of the specimen observed.

Detailed explanation-2: -COARSE ADJUSTMENT KNOB-A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.

Detailed explanation-3: -Coarse Adjustment Knob-The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus.

Detailed explanation-4: -The upper part of the arm of the microscope comprises a hollow and tubular structure known as the body tube. The body tube can be shifted down and up using the adjustment knobs. It is the smaller knob, which is used for sharp and fine focusing of the object. For accurate and sharp focusing, this knob can be used.

Detailed explanation-5: -Since the coarse-adjustment knob is used to find the specimen, combining this with the high-power objective lens could cause you to move the stage too quickly and break the slide under the lens.
