Unit 2 Test -Bone Physiology Figures

Front

What are the two main components found within the endosteum of a long bone?

Back

Endosteum and Yellow marrow

Front

What type of marrow is primarily found within the red marrow of a long bone?

Back

Red marrow

Front

What distinguishes the proximal end of a long bone from the distal end?

Back

#1 is the near end (proximal) and #3 is the far end (distal).

Front

What is an example of an irregular bone in the human body?

Back

Examples include the vertebrae and certain bones of the skull.

Front

What is the epiphysis of a long bone?

Back

The portion of a long bone with the highest concentration of spongy bone and red marrow.

Front

What is the function of yellow marrow in long bones?

Back

Yellow marrow stores fat and serves as an energy reserve.

Front

What is the role of the endosteum in bone physiology?

Back

The endosteum lines the inner surface of the bone and is involved in bone growth, repair, and remodeling.

Front

How does spongy bone differ from compact bone?

Back

Spongy bone is less dense and contains trabecular structures, while compact bone is dense and forms the outer layer of bones.

Front

What is the significance of red marrow in the human body?

Back

Red marrow is responsible for the production of blood cells (hematopoiesis).

Front

What are the main types of bone tissue?

Back

The main types of bone tissue are compact bone and spongy bone.
