Integumentary System Lab – Week Five



Introduction



The integumentary system consists of skin, hair, nails, and
nerves. As you learn about the various diseases that affect the integumentary
system, it is important for you to understand the structures that can be
affected by disease. Complete this lab to become familiar with a healthy system
and to
identify diseases related to the skin.



PART ONE: basic
functions



Provide brief answers
to the following questions to help you get acquainted with the basic functions
of a healthy integumentary system. Refer to Ch. 19 in Microbiology: Principles and Explorations.

 

1.    
How
does the integumentary system prevent disease?

2.    
How do
sweat, sebaceous (oil), and mucus secretions help prevent disease?

3.    
Which
types of bacteria are considered normal skin microflora?

4.    Suppose a sample of bacteria was taken from your skin. If
you were to perform a Gram stain on the sample, what is the likely Gram
reaction – positive or negative? Explain your answer.

Identify the selected integumentary
system structures in the following diagram:
