Long Bone Anatomy

Front

What is the primary function of red marrow?

Back

Red marrow is responsible for the production of blood cells, including red blood cells, white blood cells, and platelets.

Front

What is the diaphysis of a long bone?

Back

The diaphysis is the long, tubular shaft of a long bone, which provides strength and support.

Front

What is articular cartilage?

Back

Articular cartilage is a shiny white substance that covers the ends of bones at joints, reducing friction and absorbing shock.

Front

What is the periosteum?

Back

The periosteum is a tough membrane that covers the outer surface of bones, providing protection and serving as an attachment point for muscles and tendons.

Front

What type of marrow is found in the medullary cavity of adult long bones?

Back

In adults, the medullary cavity primarily contains yellow marrow, which is involved in fat storage.

Front

What is the role of yellow marrow in the body?

Back

Yellow marrow serves as a storage site for fats and can be converted back to red marrow if necessary.

Front

What is spongy bone?

Back

Spongy bone is a porous type of bone found at the ends of long bones and in the interior of others, providing structural support and reducing weight.

Front

How does the structure of long bones contribute to their function?

Back

The structure of long bones, with a strong diaphysis and supportive spongy bone at the ends, allows them to withstand stress and support body weight.

Front

What is the significance of the medullary cavity in long bones?

Back

The medullary cavity reduces the weight of the bone and houses bone marrow, which is crucial for blood cell production.

Front

What is the difference between red marrow and yellow marrow?

Back

Red marrow produces blood cells, while yellow marrow primarily stores fat.
