Anatomy and Physiology Honors Lecture Guide Unit 3

Unit 3 Lecture Study Guide

1. List the 4 primary tissue types and give the general characteristics and functions of each one.

The four primary tissue types include the loose connective tissue it is most widely distributed and found beneath the skin. The adipose tissue stores fat and is found around the kidneys, heart, and various joints. The fibrous connective tissue is composed of strong fibers and found in tendons. The last tissue type is the elastic connective tissue and is compose of elastic fibers and found in the walls of arteries.

2. How are epithelial tissues classified?

Epithelial tissues are classified by simple (consist of one layer of cells), stratified (two or more layers of cells), and pseudostratified (appears to be layered but isn’t).

3. How does the type of epithelial tissue relate to its function? Give at least 1 example of where you would find each type of epithelial tissue.

The epithelial tissue protects, secretes, absorbs, excrete, and sensory reception. An example is the internal and external body surfaces.

4. Differentiate between exocrine and endocrine glands. Give an example of each.

The exocrine glands remove products from the body, ex. Sweat glands. The endocrine glands helps the body communicate with the nervous system ex. Insulin.

5. What is the difference between apocrine, merocrine and holocrine glands? Which is the most common?

Apocrine glands secrete by budding off cell membranes into vesicles, merocrine glands secretes into the ducts, and holocrine glands releases there secretions by the lysis of a the cell. The most common is the merocrine gland.

6. Describe connective tissues intercellular material.

Connective tissues intercellular material is a matrix that is formed of ground substances and fibers

7. What are the 8 main types of connective tissue? Briefly describe each.

1) Loose connective tissue: found beneath the skin and...
