Front

What is the axial skeleton?

Back

The axial skeleton consists of the bones that form the long axis of the body, including the skull, vertebral column, and rib cage.

Front

Which bone is part of the axial skeleton?

Back

Sternum.

Front

What is the endosteum?

Back

The endosteum is a thin membrane that lines the inner surface of the bone, including the medullary cavity.

Front

What type of tissue is present in the skeleton before it becomes bone?

Back

Cartilage.

Front

What is the process of closed reduction in bone treatment?

Back

Closed reduction is the manipulation of a fractured bone into its proper position without surgical exposure.

Front

What is yellow marrow?

Back

Yellow marrow is the fatty tissue found in the medullary cavity of long bones in adults.

Front

What is the function of the axial skeleton?

Back

The axial skeleton supports the head, neck, and trunk, and protects the brain, spinal cord, and thoracic organs.

Front

What is the difference between red marrow and yellow marrow?

Back

Red marrow is involved in blood cell production, while yellow marrow primarily stores fat.

Front

What is the role of cartilage in the skeletal system?

Back

Cartilage provides flexible support and cushioning at joints and is a precursor to bone in the developing skeleton.

Front

What are the main components of a long bone?

Back

The main components of a long bone include the diaphysis (shaft), epiphyses (ends), and medullary cavity.
