Student objectives:
1. Define histology and tissue
2. Describe the functional relationship between cells and tissues
3. Describe the general characteristics of the 4 major types of tissue
4. Identify and differentiate among the types of epithelial tissue and indicate a location and function of each type of epithelial tissue
a. Simple squamous epithelium
b. Simple cuboidal
c. Simple columnar epithelium
d. Stratified squamous epithelium
e. Stratified columnar
i. Pseudostratified
f. Transitional epithelium
g. Glandular epithelium
5. Identify and differentiate among the types of connective tissues and indicate a location and function of each type of connective tissue
a. Areolar connective tissue
b. Adipose connective tissue
c. Dense (fibrous)
d. Fluid connective tissues
e. Hyaline/Elastic/Fibrous cartilage
f. Bone
6. Identify and differentiate among the types of muscle tissues and indicate a location and function of each type of muscle tissue
a. Skeletal muscle
b. Cardiac
c. Smooth muscle
Describe how muscle characteristics vary among the different muscle types
Striated versus non-striated
Nuclei number and location
Cell shape and arrangement
Voluntary versus involuntary
7. Identify nervous tissue and indicate a location and function for nervous tissue
a. Distinguish between neurons and neuroglia
8. Understand that tissues combine to form membranes. Be able to describe what the different membranes are and where they might be found.
Review questions:
1. Define a tissue. What are the similarities/differences between cells, tissues and organs?
2. List the four major types of tissues. What are their general characteristics?
3. The function of a tissue is actually a function of its cells. And the function of a cell is a function of its organelles. Knowing this, what type of organelles would be particularly abundant in skeletal muscle tissue that requires a lot of energy and in dense regular connective tissue that consists of tough protein strands?
4. In what areas of the body is epithelial tissue located? What are the characteristics of epithelial tissue?
5. Explain how epithelial tissue is classified according to the number of cell layers and cell shape.
6. What type of epithelium would you expect to find in the smallest blood vessels, the capillaries, which are the site of diffusion of substances between the blood and other tissues and why? What type of epithelium would you expect to find lining the vagina and why?
7. What is the function of connective tissue? How does it differ from other types of tissue?
8. What are the three major components of connective tissues?
9. How are the connective tissues classified? Describe each connective tissue in relation to the way it is classified.
10. Compare the vascular supply of bones and ligaments and discuss how this may be relevant to the clinicalcourse (ie. Healing time) of an ankle sprain versus an ankle fracture.
11. Functionally, what is unique about muscle? Describe how the three different types of muscle are similar to and different from one another.
12. Functionally, what is unique about nervous tissue? What is the role of the neuroglia and neurons?
13. What are the different tissue membranes and what role does each play?
14. Form = Function. For each of the four different tissues explain how the appearance/form of that tissue is specific to its function/to the job that it does.
