Skeletal System Review

Front

What is the Distal Epiphysis?

Back

The Distal Epiphysis is the end part of a long bone that is farthest from the body's trunk. It is involved in joint formation and is covered by articular cartilage.

Front

What is the Diaphysis?

Back

The Diaphysis is the long, tubular shaft of a long bone, which provides structural support and houses the medullary cavity.

Front

What is the Proximal Epiphysis?

Back

The Proximal Epiphysis is the end part of a long bone that is closest to the body's trunk. It plays a crucial role in joint movement and is covered by articular cartilage.

Front

What is the Epiphyseal Line?

Back

The Epiphyseal Line is a remnant of the growth plate (epiphyseal plate) in long bones, indicating where growth occurred during childhood.

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 the main functions of the skeletal system?

Back

The skeletal system supports the body, protects internal organs, stores calcium, and produces blood cells.

Front

What is Compact Bone?

Back

Compact Bone is the dense, hard outer layer of bone that provides strength and support.

Front

What is Spongy Bone?

Back

Spongy Bone is the lighter, less dense inner layer of bone that contains red bone marrow and is found at the ends of long bones.

Front

What is the role of calcium in the skeletal system?

Back

Calcium is essential for maintaining bone strength and density, and it plays a critical role in muscle contraction and nerve function.

Front

What is the medullary cavity?

Back

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