Intro to Skeletal System Review

Front

What is the diaphysis?

Back

The diaphysis is the long, tubular shaft of a long bone, which is primarily composed of compact bone and contains the medullary cavity.

Front

Where is red marrow found and what is its function?

Back

Red marrow is found in the cavities of certain bones, such as the vertebrae, ribs, and pelvis, and is responsible for the production of blood cells.

Front

What bone is located in the forearm on the thumb side?

Back

The radius is the bone located in the forearm on the thumb side.

Front

What is articular cartilage?

Back

Articular cartilage is a smooth, white tissue that covers the ends of bones in joints, allowing for smooth movement and reducing friction.

Front

What are vertebrae?

Back

Vertebrae are the individual bones that make up the vertebral column (spine), providing support and protecting the spinal cord.

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue that envelops the bones except at the surfaces of the joints.

Front

What is the function of yellow marrow?

Back

Yellow marrow primarily serves as a storage site for fat and is found in the medullary cavity of long bones.

Front

What is the role of spongy bone?

Back

Spongy bone, also known as cancellous bone, provides structural support and flexibility, and houses red marrow for blood cell production.

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity of bone shafts where red and yellow marrow is stored.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter, less dense, and found inside bones.
