CHAPTER 5: TISSUES

OBJECTIVES:
1.

Define the term tissue.

2.

Name the four primary adult tissue types, and give a brief description of each.

3.

Describe the functions and types of extracellular fluid (ECF).

4.

Compare and contrast the structure and function of the three types of cell junctions.

5.

Sketch a typical layer of epithelium. Label each structure and use this cell layer to discuss the characteristics of epithelia.

6.

Explain how epithelia are nourished.

7.

Discuss the classification scheme for epithelia.

8.

For each of the following epithelial tissues, give a structural description (including any special features such as cilia, goblet cells, etc.), denote a key body location, and identify its function(s):
A.

D.
E.
F.
G.

Simple Squamous ET
Simple Cuboidal ET
Simple Columnar ET
Pseudostratified Columnar ET
Transitional ET
Stratified Squamous ET (both keratinized and non-keratinized)
Glandular ET

9.

Distinguish between merocrine, apocrine, and holocrine exocrine glands and give an example of each. 10.

Define the term carcinoma.

11.

Describe the general characteristics of connective tissues (CT) and discuss the major structural differences from ET’s.

12.

Explain how CT’s are composed of cells plus an intercellular matrix composed of ground substance and fibers.
