Gross Anatomy of Long Bones

Front

What are Sharpey's (Perforating) Fibers?

Back

Sharpey's fibers are strong connective tissue fibers that anchor the periosteum to the underlying bone, providing stability and support.

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, often involved in joint formation.

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 is the Diaphysis?

Back

The Diaphysis is the long, tubular shaft of a long bone, primarily composed of compact bone and serving as a support structure.

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, providing structural support and flexibility.

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, playing a crucial role in blood cell production.

Front

What is the Periosteum?

Back

The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints, providing nourishment and attachment points for tendons and ligaments.

Front

What is the function of Compact Bone?

Back

Compact bone provides strength and support to the bone structure, making it dense and capable of withstanding stress.

Front

What is the Epiphyseal Line / Plate?

Back

The epiphyseal line is a remnant of the growth plate (epiphyseal plate) that indicates where bone growth occurred during childhood and adolescence.

Front

What is Yellow Bone Marrow?

Back

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