Skeletal System Review

How does the skeletal system help you move?

• By producing hormones

• By working with muscles

• By digesting nutrients

• By filtering blood

Explain why the skeletal system is essential for protecting internal organs. Use evidence from what you know about the functions of bones.

• Bones are soft and flexible, so they cushion organs.

• Bones provide a hard framework that shields organs from injury.

• Bones produce energy for organs.

• Bones store fat for organ use.

What is the main function of red marrow inside your spongy bone?

• It stores fat

• It makes red and white blood cells

• It supports the skeletal system

• It produces cartilage

Which type of marrow is responsible for storing fat in the skeletal system?

• Red marrow

• Yellow marrow

What are the two main parts of the human skeleton?

• Axial skeleton and muscular system

• Axial skeleton and appendicular skeleton

• Appendicular skeleton and nervous system

• Muscular system and nervous system

Which part of the skeleton includes the pelvic girdle and attached limbs?

• Axial skeleton

• Appendicular skeleton

• Muscular system

• Nervous system

Explain how the axial and appendicular skeletons differ in terms of the body parts they include.

• The axial skeleton includes the limbs, while the appendicular skeleton includes the cranium and spine.

• The axial skeleton includes the cranium, spine, ribs, and sternum, while the appendicular skeleton includes the shoulder area, pelvic girdle, and attached limbs.

• Both skeletons include the same body parts.

• The appendicular skeleton includes only the ribs and sternum.

What is the main function of ligaments in the skeletal system?

• They produce red blood cells

• They connect bone to bone

• They store minerals

• They cushion the ends of bones

Which of the following best describes cartilage?

• Hard tissue that forms the outer layer of bones

• Soft flexible tissue that covers mainly the ends of bones and helps cushion your bones

• Tissue that connects muscle to bone

• Fluid found inside joints

What is a joint?

• A type of bone cell

• A place in the body where two or more bones connect

• A mineral found in bones

• A type of connective tissue
