BIO 248 L INTRODUCTION, POLICIES, PROCEDURES

What you will need:

• Laboratory Manual (Marieb, 6^th Edition).
• A lab coat to wear while dissecting or working with cadavers. In lieu of this, long sleeved shirts are suggested along with clothing that you won't mind the occasional stain.
• Drawing paper and pencils. White, unlined paper, size 8.5 X 11". We will provide xerox paper or you may use your own drawing quality paper. Colored or lined paper is NOT acceptable, nor are pens for drawings. Pencils may be black lead or colored (See Drawings below)

What we provide:

• Xerox paper for drawings (See above).
• Latex or vinyl gloves for handling specimens or cadavers.
• Dissection tools, pins, etc.
• Lab Guide (You're reading it), either off the web or printed for each class. There is a generic version on the front bench, but I will provide you with the one modified for this specific section at the beginning of each lab, or you can download it from the web page.

Drawings:

All drawings must be done on white, unlined, 8.5" X 11" paper. You must use pencil, either black lead or colored. Colors should be used only to replicate the appearance of tissue, not as a key to structures or in other non-realistic ways. Structures drawn should be labeled with lines leading directly to the item. Please do not use number keys or color keys. Please print labels horizontal to the observer. Indicate the magnification at which the tissue is being observed, and make the drawings to scale as you see them as much as possible. Drawings and other assignments will be due the week following the lab, unless otherwise instructed. There will be a 10 point penalty for any assignment turned in up to a week late. Assignments will not be accepted more than one week late.

Microscope Care:

Be sure to read the handout on microscope care provided in the lab.

• You are to carry the microscope with both hands from the cabinet to your desk. Coil the cord and replace the cover when finished. Microscopes should always be left on scan or low power when finished, never on high power or oil immersion.
• Never use the oil immersion objective, or even move it into position, without the use of immersion oil. Use the oil immersion objective only when subjects are too small to be properly seen under high power (e.g. certain blood cells, capillaries), and use it only after you have thoroughly viewed the tissue under lower magnification. Clean all oil off the slide and the objective lens when finished. Objectives should only be cleaned with proper lens paper and cleaning fluid.

Safety:

• Always wear protective clothing and gloves when working with cadavers and dissected specimens. Dispose of gloves in ordinary waste receptacle.
• Use maximum care with dissection instruments: scalpels, needles, pins, etc. Notify the instructor immediately of any cuts. Dispose of used scalpel blades only in sharps containers.
• Handle only your own blood, or wear gloves when aiding another student with blood testing procedures. Dispose of blood contaminated gloves and tissues in the orange biohazard bags. Dispose of lancets, slides, and toothpicks only in the sharps containers. Do not put gloves, tissues, or other papers in sharps containers.
• Be aware of the location of eye wash stations and wash eyes and other areas immediately if they contact preservative fluid.
