Lab 5. Integumentary system
The integumentary system is a large organ system consisting of
the skin, hair, nails, and a variety of
It gives the body structural integrity, protects from the invasion of pathogens and
parasites, serves as an important sense organ, performs excretory functions, and helps to regulate our thermal
and water balances.
As we prepare to dissect the cadaver, the integumentary system is the first system
In this laboratory we will study the structure and composition of the integumentary system
through dissection of cats and the cadaver.
We will also examine models and microscope slides.
Study and learn the structure of the integument and its appendages.
Compare the integument and integumentary appendages of the cat with that of the human.
METHODS AND MATERIALS
We will begin our study of the integument by examining a model and illustrations.
Then, the structure of the
integument will be investigated by dissection of the cat.
The integumentary structures should then be reviewed
as the integument of the cadaver is carefully removed in preparation for later study of the muscular system.
During this laboratory the following materials will be studied: Embalmed cat with arteries and veins injected with
colored latex, human cadaver, model showing skin structure, and microscope slides showing structure of skin and
Students will need to bring examination gloves, scalpel, blades, and forceps.
Embalming fluid should not be allowed to contact your skin or eyes.
Protect your skin by wearing examination
gloves at all times when handling embalmed materials.
In case of accidental exposure to embalming fluid or
other preservatives, wash it off skin as soon as possible using soap and water.
In case embalming fluid
accidentally contacts eyes, wash eyes using clean water and seek medical advice if irritation persists.
