What you can expect

• Learning anatomy requires much memorization.
• Learning physiology exposes you to new concepts,
  some of which require practice and perseverance
  to understand.
• This lab course provides a foundation for further
  studies in health sciences.

5
Strategies

• Prepare for the lab before coming to class.
• Make sure you bring what is required to lab.
• Get together with others to discuss and clarify
  concepts.
• Study at least 2 times a day everyday to memorize
  anatomy.

6
Communication

• Make sure you have an activated e-mail account.
• Know how to find assignments and course
  information on my web site.
• Visit me during office hours if you have any
  questions.

7
Your Responsibilities

• Attend all labs and arrive on time.
• Be prepared for lab. Class should be the second
  time you have encountered the material.
• Finish lab assignments on time.
• Be prepared for the lab practical.
• Ask questions if something isnt clear.
• If you need any special accommodations, talk to
  me now, so we can make the necessary
  arrangements.

Care of microscope

• To carry a microscope, one hand grabs the arm and
  the other hand supports the bottom of the base.
• Never touch the lens with your fingers. The oil
  from your hands can etch the glass.
• Only clean the lens with lens paper. Other paper
  has fiber that can scratch the lens.
• When you finish using your microscope rotate to
  the lowest power objective (4X) and roll the
  nosepiece so that the space between the stage and
  nosepiece is reduced.

17
Focusing a microscope

• Turn the coarse adjustment knob to raise the eye
  tube.
• Rotate the nose piece until the 4X objective
  clicks into place.
• Adjust the diaphragm. Look through the eyepiece
  and adjust until you see a white circle of light.
• Place the slide on the stage. Gently slide the
  slide clips in place.
• Center the specimen over the aperture.

18
Focusing a microscope

• Looking from the side, lower the eye tube using
  the coarse knob until the objective almost
  touches the slide.
• Looking through the eyepiece, VERY SLOWLY rotate
  the coarse adjustment knob until the specimen
  comes into focus.
• Switch to a higher power objective and repeat
  step 6 and 7.
• Look through the eyepiece and use the fine
  adjustment knob to focus the specimen.

19
Magnification and resolution

• Magnification is the enlargement of a specimen.
  To determine magnification you take the power of
  the eyepiece X the power of the objective.
• Example A 10X eyepiece and a 4X objective
  magnifies the specimen 40X.
• Resolution is the amount of detail you can see.
  This is limited by the wavelength of light that
  illuminates the specimen.
