Quiz: Skeletal and Muscular Systems

What are the main functions of the skeletal system? Select all correct answers.

• Facilitates movement

• Supports the body

• Protects organs

• Takes in oxygen

• Excretes waste from the body

Marrow is found in the bones. What is the function of marrow in the skeletal system?

• To produce fats

• To produce calcium

• To produce cartilages

• To produce blood cells

Which statement correctly describes how the skeletal system and muscular system work together to allow for movement?

• The bone moves which pulls the tendon and muscle along with it.

• The muscle contracts and pulls the tendon which pulls the bone and allows the body to move.

• The muscle contracts and pulls the ligament which moves the bone at the joint.

• The tendon contracts which pulls the muscle and bone along with it and allows the body to move.

There are three types of muscle tissue.

• True

• False

Which statement correctly describes the types?

• A. Cardiac muscles contract the heart. Skeletal muscles move the bones. Smooth muscles are found in the arteries and veins.

• B. Cardiac muscles contract the heart. Smooth muscles move the bones. Skeletal muscles are found in the arteries and veins.

• C. Cardiac, skeletal, and smooth muscles are all voluntary.

• D. Cardiac, skeletal, and smooth muscles are all involuntary.

The skeletal system protects the organs and provides support for the body. Which of the following is an example of protection?

• The rib cage protects the heart and lungs.

• The femur supports the weight of the body.

• The skull supports the brain.

• The spine supports the body's posture.

How would you build a model using these materials to show how the skeletal and muscular systems provide movement?

• By using clay to form muscles and sticks for bones

• By drawing a diagram on paper

• By using a computer simulation

• By writing a description
