Muscle Tissues

The cellular elements of muscle tissues are specialized to produce motion by contraction. They also produce body heat. (See paragraphs 2-14 and 2-15 of lesson 2 for a discussion of muscle tissues.)

a. Smooth muscle tissue is utilized to make up the muscular portion of the various visceral organs (stomach, blood vessels, etc.).

b. Cardiac muscle tissue makes up the muscular wall of the heart--the myocardium.

c. Striated muscle tissue is used in the makeup of several types of muscles. The main type of muscle is the skeletal muscle. Other types of muscles made with striated muscle tissue are the facial or integumentary muscles and muscles of the jaw apparatus.
