Unit 3 Lecture Study Guide

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

a. Epithelial Tissue is the skin. Muscular tissue is the muscle. Nervous tissue is the nerve. Connective Tissues deals with the connective membranes in the body.

2. How are epithelial tissues classified?

b. The number of layers of cells and the shapes of cells.

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.

c. The shape of the tissue directly relates to its function. For example a simple squamous is extremely flat and it relates to diffusion and lining.

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

d. Exocrine uses ducts to secrete fluid while endocrine uses glands to direct its secretition directly into the blood stream.

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

e. Merocrine is no loss of cytoplasm. Apocrine are fragments of the gland go into secretion. Holocrine is when the whole cell becomes part of secretion.

6. Describe connective tissue’s intercellular material.

f. Mesenchyme is the common tissue of origin. The ground substance is unstructured.

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

g. Fibroblasts secrete proteins. Adipose is common in tissues. Mast cells are common beneath membranes. Leukocytes respond to injury. Plasma cells secrete antibodies. Macrophages provide protection. Chondroblasts form cartilage. Osteoblasts form bone. Hematopoietic stem cells form blood cells.

8. Describe the 3 types of cartilage? Which is the most abundant?

h. Hyaline, Fibrocartilage, and elastic. Hyaline is the most abundant.

9. Differentiate between the 3 types of muscle tissue.

i. Skeletal, cardiac, and smooth. Skeletal...
