Name:
Integumentary System Microscope Lab
The integumentary system includes the skin, hair, nails, sebaceous glands, and sweat glands. These organs
provide a protective covering for deeper tissues, aid in regulating body temperature, limit water loss, house
sensory receptors, synthesize various chemicals, and excrete small quantities of wastes. Skin varies among
different organisms in the animal kingdom. The skin of humans is very different from the skin of amphibians.
How?
Label each of the structures in the human skin:
You will use the microscopes to look at the epithelium of a frog and the epithelium of a monkey. You will sketch each
under low power (4x), medium power (10x) and high power (40x).
Quick Review:
Locate and learn each of the following parts of the microscope. Check them off the list below as you find them.
Eye Piece (Ocular)
Arm
Diaphragm
Fine Focus
Stage
Base
Coarse Focus
Clips
Objectives
Remember:
 Begin looking for your specimen under LOW power
 Focus using the course focus and fine focus
 Move to higher power and only use the FINE focus!
 When removing the slide and putting the microscope away, please make sure the microscope is
under LOW power.
Observe the frog and monkey slides using your microscope. On your data sheet, sketch each
magnification. One of the sketches for each organism should be labeled.
Clean up your lab bench, answer the post lab questions and turn in the data sheet and post lab
questions.
