Understanding Bone Structure

What is the function of articular cartilage?

• To fill the medullary cavity with yellow marrow

• To protect the ends of bones from friction and shock

• To cover the outside of a long bone

• To produce red blood cells

Where is red marrow found?

• Within the compact bone

• Inside the medullary cavity

• Covering the outside of a long bone

• In the epiphyses of long bones

What is the periosteum?

• A membrane of connective tissue covering a long bone

• A type of cartilage

• A hollow space inside the bone

• A type of bone marrow

What is the primary difference between spongy and compact bone?

• Spongy bone is vascular, while compact bone is not

• Spongy bone has microscopic spaces, while compact bone is densely packed

• Compact bone produces blood cells, while spongy bone does not

• Compact bone is found in the epiphyses, while spongy bone is not

What are epiphyseal plates responsible for?

• Bone growth in length

• Producing red blood cells

• Protecting bone ends from friction

• Bone growth in width

What fills the medullary cavity?

• Periosteum

• Yellow marrow

• Articular cartilage

• Red marrow

What is the diaphysis?

• The shaft of a bone

• The knobby ends of the bone

• A membrane covering the bone

• A type of bone marrow

What is the purpose of the nutrient foramen?

• To protect the bone from friction

• To allow bone growth in width

• To facilitate the transfer of blood to and from the bone

• To store yellow marrow
