Name the part of the central nervous system that is displayed in this tissue section. Prioritization is based on an assessment of support to the scenarios through a prioritization matrix or count of the number of occurrences throughout the scenarios. 41. Fixed smears of speciemns are required in order to perform the Gram stain and endospore stain on the specimens. When carrying the microscope, one hand should always hold the arm (and the other hand should support the base). Stage clips: Metal clips that hold the slide in place. Specimen Labeling • Specimen labeling is not required when testing is performed in the presence of the patient and only the sample from one patient is tested at a time. 5. Image 16: Mirror sets on top of the base. The ocular is connected to the body tube, which connects to the. off the slide. Has a hole in its center to allow the light from the illuminator to reach the specimen. 40. getting fingerprints in the viewing area of the slide. The specimen is illuminated by a beam of tungsten light focused on it by a sub-stage lens called a condenser, and the result is that the specimen appears dark against a bright background. m. Stage Clip: a metal clip that holds the slide on the stage ( l ). Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots, are not. The neuronal type is found throughout the entire human nervous system except in dorsal root/sensory ganglia. A major limitation of this system is the absence of contrast between the specimen and the surrounding medium, which makes it difficult to observe living cells. Place the edge of a coverslip on the slide so that it touches the edge of the water. A suspension of yeast cells makes a good practice specimen for finding difficult objects. Pillar. It can be rotated to change the magnification. contains a lens that magnifies: eyepiece: provides support for the body tube: arm: the platform where a slide is placed to be viewed: stage: allows light to pass through the slide: stage opening: used to bring the specimen into sharp focus and bring out details: fine adjustment knob: used to focus the microscope by bringing the slide into focus . 2.

Note: Changing the order of objects can affect how the slide looks when there are overlapping objects.If the slide does not look the way you want after changing the order, press Ctrl+Z to undo the change. (Tip: If you are using thin slides and can't focus, rather than adjust the rack stop, place a clear glass slide under the original slide to raise it a bit higher). Cut out a letter "e" from a newspaper or other printed page. Flood the slide with iodine for 1 minute 5. Illuminator. 2. Thus, enriched media are capable of providing nutrients to nutritionally exacting organisms as well. A single slide can be represented either by a Slide object or by a SlideRangecollection that contains only one slide, depending on how you return a reference to the slide. Tube. Rinse with H20 6. (c) This tissue sample is being fixed in a solution of formalin (also known as formaldehyde). Part of the microscope that supports the slide that is being viewed. Staining • A technique in microscopy that is used to enhance the image of the specimen. Figure 4.3. Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year 1590 (more history here).The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope (versus an electron microscope). First of all, you have to place a coverslip over the specimen sample. Why should a glass slide and a coverslip be held by their edges? Figure 1. Architectural design and construction. Thin clear rectangular pieces of glass upon. Heat fix the sample to the slide by carefully passing the slide with a drop or small piece of sample on it through a Bunsen burner three times. Always center the specimen over this hole. Support the slide which contains the specimen. Some modern microscopes contain mechanical stage, with adjustment knobs that allow for more precise positioning of slides. COVER SLIP. Reinforced concrete design 2. Arm. The first reagent (Crystal Violet) is the primary stain.It gives color to all cells. Condenser lenses are most useful at the highest powers (400x and above). Illumination - It is the light used to illuminate the slide that contains the specimen. One knob controls forward/reverse movement of the slide. This manual is specific to a PowerPoint slide deck related to Module 4, Architectural design 13. A sputum specimen recieved at 8 am for an AFB smear reveals acid fast bacilli.
