Flashcard 11/6 HBS

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity of bone shafts where yellow marrow is stored, and it plays a role in the production of blood cells.

Front

What is articular cartilage?

Back

Articular cartilage is a smooth, white tissue that covers the ends of bones where they come together to form joints, providing a cushion and reducing friction during movement.

Front

What is yellow marrow?

Back

Yellow marrow is a type of bone marrow that primarily stores fat and is found in the medullary cavity of long bones.

Front

What diagnostic imaging technique is especially useful for soft tissue injuries, such as ligament tears?

Back

MRI (Magnetic Resonance Imaging) is especially useful for diagnosing soft tissue injuries, as it provides detailed images of soft tissues.

Front

What is compact bone?

Back

Compact bone is the dense, hard outer layer of bone that provides strength and support, making up the majority of the bone's structure.

Front

What is the function of the medullary cavity in bones?

Back

The medullary cavity serves as a storage area for fat (yellow marrow) and is involved in the production of blood cells (red marrow in certain bones).

Front

How does articular cartilage contribute to joint function?

Back

Articular cartilage reduces friction between bones in a joint and absorbs shock, allowing for smooth movement.

Front

What are the differences between yellow marrow and red marrow?

Back

Yellow marrow primarily stores fat and is found in the medullary cavity, while red marrow is involved in blood cell production and is found in certain bones.

Front

What are the advantages of using MRI over X-rays for soft tissue injuries?

Back

MRI provides more detailed images of soft tissues, allowing for better visualization of ligaments, tendons, and cartilage compared to X-rays, which primarily show bone.

Front

What is the composition of compact bone?

Back

Compact bone is composed of tightly packed osteons (Haversian systems) that provide strength and structure, with a matrix of collagen fibers and mineral deposits.
