Integumentary Structures Objectives

Describe the major structures of the integumentary system including cells and their products.
List the various functions of the integumentary system.
Explain how the integumentary system relates to thermoregulation.

Warm up:

From your notes, what is the difference between an observation and an inference?

This video introduces the integumentary system.

Now that you have background on basic integumentary structures in the skin, this video introduces their functions.

You are not turning in your lecture notes for this guide, there is a different media piece introduced on the next page. However you will still be able to use your notes for the quiz.

From your lecture notes, name the tissues that make up the epidermis, dermis, and hypodermis of the skin.

The suffix –cyte means _________.

Keratinocytes in the epidermis produce __________.

Melanocytes in the epidermis produce __________.

Fibroblasts in the dermis build (make) ___________.

Epithelial tissues typically ____ organs.

List the three basic shapes of cells within epithelial tissues.

Connective tissue are typically the _____ of an organ.

List five different types of connective tissues.

What happens to the connective tissue of the dermis if fibroblasts do not produce sufficient collagen? Wound healing can be quite slow.

The skin plays a significant role in thermoregulation.

Heating the Body

From your lab activity, what occurs in the skin that will lead to an increase in heat retention and a decrease in heat loss?

Cooling the Body

What occurs in the skin to release/dissipate heat?

Amazingly, some of the things we commonly experience with our skin have only recently been explained, like skin wrinkling in water.

The next section explores integumentary health and safety.

Check your knowledge. Can you:
