Lab Activities

The lab work in this unit will focus on the identification of various types of
epithelial tissue and connective tissue. These activities will require the use of
a microscope, your textbook or other lab manuals to aid in the identification
of these tissues. The microscopes in our lab have three objectives lens with
powers of 4X, 10X, and 40X. When studying tissues you need to “find” the
specimen on the slide with the low power 4X lens then use the higher power
lenses to see the finer details of the tissue.

Table 1 in the study guide lists the various types of epithelial tissues that you
will observe; Table 2 lists the types of connective tissues that you are
expected to know. Both tables provide information as to the location of these
tissues in the human body; you should fill in the blanks as to the function of
these tissues.

Gloves and safety classes
Lab coat or apron

General Directions:

bag to put the cat back into after each lab period.
3. Pour the liquid in the bag down the sink.
4. Place the cat on a large aluminum dissecting tray for dissection. These
trays must be cleaned and dried after every use.
5. VERY IMPORTANT: all the hair, tissue, fat and other cat material must
be disposed of in the proper container, NOT IN THE TRASH CANS! Please
do not put gloves and paper towels in the cat tissue container.
6. After your group has finished dissection for the evening, the dissection
tray must be cleaned, dried and put away. Your lab bench area must also be
cleaned and disinfected.
