Long Bone Flashcard

Front

What is the medullary cavity?

Back

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

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 a cushion and reducing friction during movement.

Front

What is the diaphysis?

Back

The diaphysis is the long, tubular shaft of a long bone, primarily composed of compact bone, which provides strength and support.

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, serving as an attachment point for muscles and tendons.

Front

What is compact bone?

Back

Compact bone is the dense, hard outer layer of bone that provides strength and support, making up the majority of the bone's 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, containing red bone marrow.

Front

What is the epiphysis?

Back

The epiphysis is the end part of a long bone, initially growing separately from the shaft, and is involved in joint formation.

Front

What is the function of the endosteum?

Back

The endosteum is a thin membrane lining the medullary cavity, involved in bone growth, repair, and remodeling.

Front

What is the role of bone marrow?

Back

Bone marrow is the soft tissue found in the medullary cavity of bones, responsible for producing blood cells and storing fat.

Front

What is the significance of the nutrient artery?

Back

The nutrient artery supplies blood to the bone, providing essential nutrients and oxygen for bone health and maintenance.
