Front

What is Spongy Bone?

Back

A type of bone that is lighter and less dense than compact bone, found at the ends of long bones and in the interior of others, providing structural support and flexibility.

Front

What is Compact Bone?

Back

A dense and strong type of bone that forms the outer layer of bones, providing strength and support.

Front

What is Articular Cartilage?

Back

A smooth, white tissue that covers the ends of bones where they come together to form joints, reducing friction and absorbing shock.

Front

What is the Epiphyseal Line?

Back

A remnant of the growth plate (epiphyseal plate) in long bones, indicating where bone growth occurred during development.

Front

What is the Periosteum?

Back

A dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints, serving as a point of attachment for muscles and tendons.

Front

What is the Medullary Cavity?

Back

The central cavity of bone shafts where red and yellow bone marrow is stored, playing a crucial role in the production of blood cells.

Front

What is Yellow Marrow?

Back

A type of bone marrow that is primarily made up of fat cells and serves as a storage site for fats, found in the medullary cavity of long bones.

Front

What is the Proximal Epiphysis?

Back

The end part of a long bone that is closest to the body's trunk, containing spongy bone and red marrow.

Front

What is the Distal Epiphysis?

Back

The end part of a long bone that is farthest from the body's trunk, also containing spongy bone and red marrow.

Front

What type of bone is the Sacrum?

Back

The sacrum is classified as an irregular bone, which has a complex shape that does not fit into the other categories of bone.
