• Skeletal muscle

• Connective muscle

Which of the following describes the function of smooth muscle?

• Production of heat

What is the main structural difference between skeletal and smooth muscle tissue?

• Skeletal muscle is involuntary, while smooth muscle is voluntary.

• Skeletal muscle is striated, while smooth muscle is non-striated.

• Smooth muscle has intercalated discs, while skeletal muscle does not.

• Smooth muscle is attached to bones, while skeletal muscle is not.

Which of the following best describes the role of muscles in maintaining posture?
