Identify the structures, functions, and diseases of the muscular system.

Identification should include

• the function of the muscular system
• skeletal muscle (striated)—moves the body and operates with conscious control
• cardiac muscle (striated)—forms the wall of the heart and is not under conscious control
• visceral (smooth)—involuntary muscles that form the walls of organs and are not under conscious control
• diseases/disorders of the muscular system.

Process/Skill Questions:

• What is the difference between voluntary and involuntary muscle? Why is each important?
• How are muscles attached to bones?
• What muscles are used when performing curl ups?
• What is the significant characteristic differentiating cardiac muscle from other muscle tissues?
• What are the major disorders of the muscular system?
• How are the cardiac, voluntary, and involuntary muscles alike? How are they different?
• What would cause muscles to atrophy?
