LT4.2 Bone Anatomy & Function

Front

What is the proximal epiphysis?

Back

The proximal epiphysis is the end of a long bone that is closest to the body's trunk, typically involved in joint formation.

Front

What is the diaphysis of a bone?

Back

The diaphysis is the shaft or central part of a long bone, primarily composed of compact bone.

Front

What type of bone is found in the diaphysis?

Back

The diaphysis is primarily made up of compact bone, which provides strength and support.

Front

What is the epiphyseal line?

Back

The epiphyseal line is a thin plate of cartilage that separates the epiphysis from the diaphysis in a growing bone.

Front

Where is compact bone found?

Back

Compact bone is found in high-stress areas of the skeleton, providing strength and resistance to bending.

Front

What is spongy bone?

Back

Spongy bone, also known as cancellous bone, is a lighter, less dense bone found at the ends of long bones and in the interior of others.

Front

What is the function of articular cartilage?

Back

Articular cartilage covers the surfaces of bones at joints, reducing friction and absorbing shock.

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 role of red marrow?

Back

Red marrow is responsible for the production of blood cells and is found in certain bones.

Front

What is the difference between compact and spongy bone?

Back

Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter and has a porous structure.
