Textbook Question
Chapter 10, Problem 2.1CT
The word fiber is used to describe a structure in three of the four primary (main) tissue types. In connective tissues, a fiber is a protein strand that is collagen, reticular, or elastic. The meaning of the word fiber is different in muscle tissue and in nervous tissue. Explain a fiber in each of these two tissue types.

The ratio of cells to extracellular matrix is a major difference between epíthelial tissues and
connective tissues.
What relationship between epithelial tissues and connective tissues is important for the survival and
function of epithelial tissues?
The thick, pink-staining fibers that you are viewing on
the photograph are what type of fiber?
The very fine, dark-staining (blue purple) fibers are what
type of fiber?
Most of the cells that you see are fibroblasts. They can
be identified by the dark-staining nuclei scattered
throughout the specimen. The cytoplasm of these cells
stains weakly and cannot be easily identified. Refer to
your text and describe the function of these cells.
Lack of vitamin Cin the diet interferes with the ability of fibroblasts to produce collagen. How might this
affect connective tissue function?

- Collagenopathies, conditions characterized by the production of one or more types of defective collagen proteins, are in a group of disorders called connective tissue diseases. Many collagenopathies feature arthritis or other joint problems as part of the symptoms of the disorder.
