Period:
Unit 2/Chapter 6: Integumentary System (p. 169-191)
OBJECTIVES:

Explain why the skin is called the cutaneous membrane.

Name the layers of the skin, describe the structure (tissues) of each, and name a general
function of each.

Discuss the four cell types present in the epidermis.

List the four/five layers of the epidermis and explain the process of keratinization.

Explain the protective role of keratin, and in turn, the epidermis.

Name the pigment responsible for skin and hair color, and explain how people of different
races (i.e. and skin color) differ in regards to it, and the cell that produces it.

List some factors that promote the production of melanin (besides DNA).

Distinguish between the papillary layer and reticular layer of the dermis, and locate the
appropriate sensory receptor in each of these layers.

Compare and contrast tactile (Meissner’s) and lamellated (Pacinian) corpuscles in terms of
their structure, function, and location.

Describe the structure and function of the subcutaneous layer.

Explain what is meant by the term epidermal derivative, and list four examples.

Describe the general structure of a hair follicle and identify two other structures that are
usually associated with them.

Distinguish between merocrine (eccrine) and apocrine sweat glands in terms of structure,
secretion content and odor, activation, and major body locations.

Name two modified apocrine glands of the skin.

Describe the structure, function, secretion, and location of sebaceous glands.


Discuss the many functions of skin.

Describe some major homeostatic imbalances of the skin.

Sketch a typical layer of skin and label each layer and all structures. Then in complete
sentences, discuss the function of each layer and structure.

Discuss heat production and loss as it relates to the integumentary system.

Define the terms hyperthermia and hypothermia and discuss the cause(s) of each condition.

Discuss the healing of cuts/wounds that occur to the skin.

Distinguish between 1st degree, 2nd degree, and 3rd degree burns, and discuss the
process by which each burn heals.
