CH4 Skeletal System REVIEW

The primary function of the skeletal system that provides shape and internal framework for the body is

• protection

• support

• storage

• movement

Which function of the skeletal system occurs in trabecular bone?

• protection

• storage

• blood cell formation

• movement

Which mineral stored in bone is essential for muscle contraction and blood clotting?

• potassium

• calcium

• iron

• sodium

The ribs protect which organs?

• liver and kidneys

• heart and lungs

• brain and spinal cord

• stomach and intestines

Which organ is enclosed by the skull?

• Kidneys

• Brain

• Liver

• Lungs

The two main types of bone tissue are:

• hard and soft

• trabecular and cortical

• trabecular and cancellous

• cortical and compact

Compact bone is composed of structural units called:

• trabeculae

• osteons

• lacunae

• lamellae

The porous network of bone that contains red bone marrow is called:

• cortical bone

• trabecular bone

• medullary cavity

• epiphyseal plate

Which type of bone is located primarily in the outer layer of all bones?

• cortical

• trabecular

• cancellous

• spongy

The periosteum is important because it:

• contains marrow

• covers the outer bone surface

• stores minerals

• lines the medullary cavity
