Which of the following best describes single-unit smooth muscle tissue?
a. The fibers function individually.

Suppose that a new type of muscle tissue is discovered and, like the other types, it generates tension. Would you expect this new tissue type to have the same basic structure as skeletal, smooth, and cardiac muscle tissues? Why or why not?
In an examination of a sample of muscle tissue, you notice that thesample consists of striated cells with multiple nuclei in each cell.This suggests that the sample is from which of the following typesof muscle?a. cardiac c. skeletalb. smooth d. Both b and c are correct.
All of the following characteristics apply to skeletal muscle except
a. They are striated.
b. They are multinucleated.
c. They are voluntary.
d. They contain intercalated discs.
e. They are attached to the skeleton by means of tendons.
