Long Bone Anatomy

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 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 cushioning and reducing friction.

Front

What is the Epiphyseal Plate?

Back

The epiphyseal plate, also known as the growth plate, is a hyaline cartilage plate located at the ends of long bones, allowing for growth in length during childhood and adolescence.

Front

What is Compact Bone?

Back

Compact bone is the dense, hard layer of bone tissue that provides strength and support, making up the outer layer of bones.

Front

What is Endosteum?

Back

The endosteum is a thin membrane that lines the inner surface of the bone, including the medullary cavity, and is involved in bone growth and repair.

Front

What is the function of the Medullary Cavity?

Back

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

Front

What is Periosteum?

Back

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

Front

What is Trabecular Bone?

Back

Trabecular bone, also known as spongy 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 role of Osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.

Front

What are Osteoblasts?

Back

Osteoblasts are bone-forming cells that synthesize and secrete the bone matrix, playing a key role in bone growth and healing.
